we found where the oil was coming from... it's NOT good! can we get it back together soon?! 

It is badass to see Jackie in front of the camera laughing and joking. Much love and respect to you both ❤️✌🏻

Big Chief is so lucky to have Jackie. She's inspirational when your not feeling great and seems to look on the positive side of things. Also, she's always there to lend a hand when you need it, so cool Jackie, keep up the good work. Big Chief needs some extra love until he finds his way.

We need a Midwest Street Cats T-Shirt 😂

The perks of running *Nitrous* !!! (Rod and or rod bearing checked out a pass or 2 prior) The final burnout was the icing on his cake!

Loving you guys and your content! Jackie keep Chief grounded, Chief keep Jackie’s head in the clouds!

Big When will you return to racing, I didn't find any of your races from 2023, I'm your fan, I live here in Brazil 🇧🇷✌️, big hug.

It appears Caddy Jack got scared thinking about Tommy Hopscotch and the Ranchero lining up in the other lane. 🤣😅

I am very much pro a “Midwest Street Cats” t shirt. Thank you for all the kittah footage!! 😻😻 Sorry the engine broke!

I think Jackie's on to something with the 'collar, no collar.' Probably led to the valve decapitation.

I see what happened 😱men are from mars women are from Venus and the rods are from scrappy dooo 😮 lmao 🤣 always have me laughing on your vids thanks 🙏

Now I see why Jackie does rev limiter burn outs, finds the weak parts before the pass.

Sucks…. Part of learning a new combination. Not knowing what it should run in different weather conditions. If you guys had a better handle on it, probably could have pulled/cut the filter and found a problem before it let go completely. I think I’m going to invest in a system 1 filter for the Malibu. Sorry Jackie. 🥹

Love how you guys take care of the cats as much as you do!! Wishing nothing but the best of luck for you guys. I wish to someday see caddy jack spank them newer Camaros…

You guys are so awesome to watch. I can’t tell you how much I enjoy the chemistry and banter you have with each other. Couples goals. And fast hotrods to boot!

Lol, the rod put in his 2 weeks notice 🤣. Unfortunately I think we all know that feeling to some extent. Big ups guys, love the vids as usual 🙏🏼.

SHE SAID.... NO YOU GOT LUCKY, IT AINT MY MOTOR 🤣

Lol, Chief fixing to put a burnout switch on the back bumper... lol

Was literally just rewatching the war in the Woods video. Really cool seeing you giving Kyle his 💐. Winning the whole thing was a plus. Yall keep doing you if it makes you happy 🖕em.

WHAT DA F---K , I Wouldn't believe it If I didn't it, sounder so solid up to the Gernade, THAT SUCKS POUR RODS OR BALANCING SORRY Jackie n Big Chief Have a Better day God Bless America 🇺🇸🙏🇺🇸

Jackie always finds the bright spot of a situation. That was the best place to break it.

Shit I'm getting old, I died laughing at Jackie's price of a chimney joke. Like cracked up at it. Thanks for the laugh, I could always use a good laugh.

That's a tough one! It most certainly looks like oil starvation on that rod journal. Unfortunately, I have had one that looks like that before 😂 I'm not super familiar with the SBC oiling system, I'm a weird small block dodge guy, but I think that rod is fed off of #4 main?? Maybe the higher than normal oil pressure is an indicator of partial blockage or restriction. Maybe the main bearing has a story to tell when you get further into it. Or if there isn't a blockage to be found, maybe rod side clearance is too tight? If you can't get the oil out fast enough, hard to get new oil in on the rod journal. I'm not sure, just brainstorming ideas. Looking forward to what you find!

With all the craziness/insanity that Caddy Jack has provided.. Y'all still can smile and laugh about it without blowing up! From the last vidja, who would have thought a rod went stage left... Bet CV pressure bounced off the zero peg HARD!!! YOU GUYS ROCK! Pull CJ's pants back up and boil some more pavement! Prayers and Blessings to you both!

This channel and you guys are so much more relatable than the other 405 channels. No flexing or performing for the camera, just 2 down to earth people sharing their passion and knowledge for racing.... and Cats too. 😉😂 Peace 🤘🤘

Jesus man, did you let Kamikaze loose on that motor with a few tubes of silicone?

Does your data logger record during the burnout? You using a some kind of two step on the burnout? It sounds really high rpm to me, like either valve floating on burnout or up on the limiter set at 8000+. Valve float @ around 8500, 9000, part throttle so very little downward pressure on piston = very hard on con rods. I'd keep the burnout rpm 7000 max. It's still very unlikely that would cause a rod failure though. Until you can rule out lack of lube on the bearing by finishing the tear down, this would be my second guess following lack of lube. Third guess, that piston was installed backwards cause how it was rotated during removal, and it wanted out lol.

Perhaps the bearing clearance was to tight? One thing is for sure is that you’ll get her back up and running kicking ass!

That oil emergency exit will never keep oilers woking lol nice window though, good job , do you have a the 2 inch relief pipe from the crank case running out the trunk , just check out Morris on his fix for blowing up pro mod / all drag cars lol ,,, BigAl California u rock , thanks praise Jesus Christ grace amen 🙏

So nice to see that the cats are happy with you guys! You really take care of them ❤ I wish you find out what's the issue with the engine because I'm sure it had nothing to do with your driving style Jackie.

Chief and Jackie I love your videos you do things totally different to anyone else and don’t hide shit!! That SBC issue is just shit luck.. A few times in previous videos even from some of the 1st passes it’s sounded a little strange in the burnout especially at high rpm it changed note and sounded different.. was it over reving in the burnout at the point there’s no real load on the engine as the wheels are spinning? Not enough valve spring? Or even too much? Or just plain and simple too many rpms??? I had the same thought also from how short the conrod broke to the piston?? Keep up the great work! Sending positive thoughts from the UK , cheers Dancey

🤣 TOOK 6 MONTH'S TO GET TOGETHER IN THE CAR... 45 MINUTES TO RIP IT OUT

I would just think if you can't logically see a reason, I would think you had a bad rod, weak. Just saying 🙂.

Another great video, sucks that happened and I'm certain you all will figure out what caused it. Looking forward to Gerald's thoughts on it on the next video. Keep do you guys cause everyone is watching

Jackie mentioned "the oil pressure was really high".. more so than normal by the sound of it. Also, it looks like that one bearing was starving for oil. Is there any chance the rod bearing was blocking the oiling hole so oil couldn't flow through the bearing. Which would raise oil pressure due to blockage AND kill the rod bearing?

Sometimes parts just fail...with the rings being in such good shape, it doesn't appear that cylinder was starved for oil, unless a bearing spun on the rod journal causing it to lock on the crank and snap the rod...

It will be interesting to see what the crank and bearing look like for that cylinder.

You guys don't have great luck with used engines. Can't trust used race engines. BTK learned the same thing the hard way. I dont see anything you guys did wrong and I don't think you could have seen it coming short of tearing the engine down before putting it in Caddy Jack.

Nice to see Jackie on the other side of the camera! I’m sure the rev limiter burnouts had no effect 😂😁

There's some blockage in that block. Internal oil issues. Get you a new block brother.

Nice to see you guys doing your thang if I could afford it I would take my P.O.S car to you guys Jackie is lucky to have a master genius who knows his stuff. Miss Big Cheif on TV but the videos help a little, good to see you both smiling and keeping grounded much love to both of you. Chief do you ever age? LOL always has that glow to him that's pure happiness I hope❤❤❤

Damn! Seeing that slop job of sealant on the rear of the intake & the “back of the heads”? What’s up with that? I think seeing that would have made me do a 6 second turn & burn away from that engine! Makes ya wonder what kind of job was done on the inside of that engine?

Love you'll keeping us updated. You'll are our favorites

I've heard cat hair reduces lubrication for rods......👍🏁

Roofing jokes are expensive but I’ll give you the first one on the house! 😫

I'm no expert like you but my theory on why caddy jacks slow down the way it did on the previous passes is because that rocker arm failed or was failing I just can't see anyting you guys were doing causing the latter to happen first .. there's absolutely no way I can see you leaned on it enough for a rod to Just let go.. I get it it's a race car and parts fail sometimes but that's just a little suspicious the way it's slowed down before that

So glad to see Jackie back being herself!! Rooga rooga

Ya well the flux capacitor released too many Tacion particles and it shit itself. There done! Now you know!

Soooo friggin bummed for you guys, I was soo wanting to see caddy jack dole out some sweet Ole fashion azz whoopin soon.... Thank goodness it didn't happen during a full pass on the bottle. Nothing but love to you guys and can't wait to see it fixed and running again. Thank you for sharing, everyone keep yourselves and love ones safe and healthy and remember to SMILE 🤪😜

Put a stop on the throttle like a top fuel car , if you don’t have the oil relief pipe or pipes I think it’s one pipe from the crankcase to relieve all that oil fume pressure from agitated oil on a run then that could maybe made thing tighten up , just make sure your crank case relief pressure pipe is free of all rodents and debris flows the over pressure from the crank case out through the pipe in the trunk at the top of the trunk ok thanks it’s just her life and some work , good vlog ,,,BigAl California thanks praise Jesus Christ grace grace amen 🙏

Ms Jackie , Mr chief will fix that deal !! Please don’t change the burnouts they are on point 💯. Good job on the videos. 👍👍

Bad rod casting mabey . Check your bearings see if they were starting to waire weard but in the pattern like when you pulled it down the first time,. Check rod clearance between compared to rod journal with on crank mabey a harmonic thing traveling up the rod.i think it let go on deceleration.but your dad was with u mabey he seen something an chose that was the rite time not cople sec later God bless

I love this series yall are makin. It's informative and wholesome. Thank you!

We had 2 rods fail last week and neither us nor the builder, the manufacturer have an actual reason why it's happening other than bad batch. Just really strange

Can't wait to see you guys get it straightened out and make some good, clean, fast passes. The limiter burnouts make me cringe! Lol

So glad to see y'all doing this y'all look Happier then ever

I Always start from bottom to top with an oiling issue. Assuming that's a gm cast block I would be looking for cap walk, cylinder distortion or cracking in the main webbing or block itself.

I got to the shop this morning an there was a guy there drinking brake fluid.. before I could ask what he was doing, he held up his hand and said "don't worry, I can stop anytime."

This motor always sounded wrong on the 2 step and the limiter to me... It just sounded wrong.

Chief you won the best joke 🤣 My heart goes out To and Jackie. Hopefully it is easy fix 👍💯🤙

Should mention... Clean that piston and rod, both of you sign it, and put it up for sale. I bet someone will buy it!

Just want to thank Jack for breaking during a burnout and not 4 seconds into a pass.

Manufacturer issue? Steve Morris lost all 8 rods in his wagon, just a bad batch he said

Love ur technique as a mechanic myself. And glad to see Jackie back in videos

I'm going to lean towards it starving for oil and stacking the bearings then welding itself to the crank throw causing the rod bolts to break thus causing the rod to twist and break itself. 🤔

She has a good eye on stuff that doesn't look right 👍. sorry that happened guys but glad she wasn't in a pass when it happened could have been a crash . great video guys keep them coming I can't wait to see what you do next

Maybe too much oil pressure and lifted a crank bearing.

Great content you two! My theory is the piston broke. Lol

Just my two cents worth is it was know ones fault. It looks like the rod just gave out. Have seen a lot of rods in my time break in the same place and be a tired rod. Keep good spirits is the ticket.

Crank & bearing inspection is a must. I was always taught start at the bottom and work your way up on the engine. Good luck guys...

So most of the lifters have offset cups and do they have a flat side to keep them from spinning, looked like some of intake pushrods are really close to head, It's hard to tell from video are chamfers on rods facing wrong way on that journal? Like ya'lls videos nice to see you two back at it. Was that the other motor that came with the corvette?

Glad that the block looked okay, and the heads were relatively intact. That's a good start. I would still tune the rev limiter differently. And the mysterious stutter on the fast pass is still unsolved. Right before the finish line. On a high compression engine, the risk of hydro lock is always present, and in this case most likely culprit. The rod didn't look like it had catched the rod bearing, it just got beat up. BUT this is also a mystery engine. So although banging against a hard limiter is never a good thing, there's still oil clearances, mismatch rod pairs, and the simple harmonics created by the rev limiter. There was also a lot of fuel in the oil, so the cylinder could've got dry and heated the piston. What if the excess oil pressure is due to clogged oil passage? And even with the risk of losing the heart, when running carburetor(s), flooring it on the leave is more benefitial than having it floored in the beams. This way there's more air velocity and thus more fuel in the system at the launch. This way you can arm the nitrous based on pedal position directly, and the delay comes naturally. Also, rich mix at the start on low rpm creates softer combustion. Although the initial hit on the tyre is harder, it is also softer. Was it just the driving? No. Was it just the tune? No. Was it just the engine? No. It was like it always is, a combination of all of these. Again, it popped the intake way back when second outing at the street. It also hopped the tyres when the rear was too stiff. All of these are the seeds to the rod failure. Every fallen dam had a tiny hairline crack first. Also I would like to thank you for proving me wrong last week, and uploading two videos on YT. That was amazing. And I would like to buy a hoodie, but I'm flat broke. Maybe some day when I get over the poverty line, though not gonna happen in near future. From Siberia, with love.

Think that hard hit on the nitrous when the hz were off hurt the rod and it was just hanging on ever since. Finally decided to let go. Just glad it wasn't down track.

Does it run the same rpm in the burnout and making a pass because it sounds like during the burnout it's gonna come apart?

Joke of the day was great..... Not blowing up in the middle of the run and Jackie is safe even better. Salute.

Hate to see it, hope it's obvious what caused it and easily fixed.

It spun rod bearing then locked rod to crank, broke rod, piston made contact with valve, valve couldn’t open, rocker said we will see about that and broke. I don’t know what oil you run but it looks like rust color. Strange but not the cause of spun bearing.

🎮 My business on my gta game is midwest St cars 😁😁👍👍👍

Man we all know it’s apart of racing anything competitive… But man to run a legit nitrous set up your gonna need a machine shop by your side to get you in and out. And we all know how long motors take.. idk I love nitrous but I mean shit…

Do you use a mechanical oil pressure sensor? Over rev in the burnout...

So was I right about the horsepower from long time ago just curious 🤔

Engines be weird some times. Made a pass one time in Jack Black, puffed smoke on the big end, engine sounded fine. Drove it on the trailer, a group of 5-6 of us around the truck nobody heard anything weird. Got it home and pulled the engine, hole through both sides of the pan and 2 rods said "Sayonara, Amigo!" Like how the heck? Aliens, I guess

I’m wondering if the spring on that cylinder weakened and floated the valve kissing the piston sticking it open a little and causing detonation in that cylinder. As for the rod journal on the crank not having oil I’m wondering if the previous pass is when the initial damage happened and caused bearing damage causing zero oil on the next pass when the motor let go. 1,000 different things could’ve went wrong but it could be the simplest thing that caused it

Oh my! So lucky you shut the car off when you did. Glad the motor can be redone and you are safe. Those fast passes and the tuning were getting too fast and luck ran out. I know ya'll were checking plugs each run and it's sad they didn't show anything prior to this mishap. I believe the valve shoulder comment should be looked at closer. 1.) Maybe wrong valve order? 2.) Or maybe after the prior aggressive passes the valve lash needed checking/tweaking? 3.) Car warmed up enough? Or maybe hot engine expanded piston/ rings dimensions too quick for adequate lubrication causing friction on piston and resulting in failure? 🤔 Very intriguing since things seemed to be getting closer to being dialed in. 4) mentioned that one pushrod was hitting other rocker arm... was this rocker arm ( the one with the loose pushrod) loose?, pushrod shorter than required), bent or snapped and then hitting the other rockerarm? ( curious). I know you guys will figure it out and I hope to see you in the 4's very very soon! ;) ya'll rock!

Mistress Jackie. the rev limiter dominatrix

Sorry guys i know this sucks big time, how many passes did engine have?? 👍👍

Thanks for the awesome content. I have to say that I am able to give you two thumbs up. My sister owns a fire TV. I have a plan with. Straight talk phone. So I'm able to give you two thumbs up. Not able to buy merch sorry about that. Because of the president of the United States. But at least it's something from RU-vid. I know you guys will get it together.

Is there any way one of the rod bolt where not torqued All of the way down

Hope one here can help you so we can se that badass car on road

“because I’m petty” that was priceless! Sorry to see this but glad you didn’t scratch that gorgeous Caddy! Onward!

loving the vids glad the jokes are back lol

That bearing spun, tightened up and blew the bottom of the rod off

May have had a tight bearing clearance 🤷🏽‍♂️ wasn’t a problem till the bottle, that may have been enough to hurt it. Hope you fix it soon, so hooked on the channel.. think you guys are awesome together

LIKED THE VIDEO BIG CHIEF AND JACKIE HOPE YOU GET A ENGINE BACK IN CADDY JACK PRETTY QUICK SEE YOU NEXT TIME STAY SAFE

DAM CHIEF YOU AIN'T RIGHT ( CAN'T FIND HOME ) FUNNY.

great content... I'll take a hat to help with the rebuild... is this just a NO2 thing? or single unit failure???

Ole lead foot sally there 8800 in the water box

Y'all do what you do that's all you can do fix it.

I can hear chief now. "Yeah lets build a nitrous engine she said" It'll be fun she said "

Jackie I don't think it was driver error

Big Chief I would be looking through the oil passages on the crank to make sure they are clear. On that rod double-check that your holes were lined up on your mains. I know what you thinking there would have been other ones affected top half of the motor to but I like to check everything. Then I would probably just be curious that maybe that rod bearing turned a little in the cap like you said that rod put it's two weeks in or the bearing did! Maybe the tabs broke off the bearing and turned spinning during the first run an most the time blocking the oil Passage to that rod. Had to guess I would say it happened in the first run when you lost power. But like yourself I would have to inspect every inch of that motor to come up with the best conclusion so I know how I would want to put it back together. Can't wait to hear what your conclusion is. Good luck bro.
