Do not change showing us the detail and truth. I learn so much. It changes how you think about things. Nothing like reality, not fantasy. In racing you cannot lie. The lights tell all without prejudice of any kind.
4.20’s on a 3600 lb car, on any car for that matter, is flying period. Especially one you can drive to lunch or the store or 1000 miles. Amazing numbers and an awesome car. Keep up the amazing work.
Steve is like a teacher I had when I was studying mechanical engineering: a man with practical experience, in for a joke at a timebut still very serious, never afraid to be humble, and always asks the question “why is it that way” at the right time, and wanting to teach everyone what he has learned to those who are interested. This teacher gave material science, construction calculations, and a heck of a lot of other subjects, and restored harley davidson gearboxes as a hobby. In those years he had done more than 150 gearboxes. Steve, Kyle and crew, you guys are amazing, and please never quit teaching us on things you learn along the way of failure or success!
I use to work on a top alcohol team. We killed 2 engine with 1 broken valve in the same way. It broke, pieces bounced around, then went up into the supercharger (we didn't look up in there). Take the blower off put it on another engine. Go do another run, have another boom. Find the broken valve from engine 1 in engine 2. Not fun.
@Ayedidyae LMAO Forza kids okay bud. There is an intake manifold that the supercharger sits on. We didn't always unbolt the supercharger from that manifold. Just unbolt from the heads and move to a different engine. The piece of the valve was in that manifold. That stayed attached to the supercharger as we swapped from one motor to the other. Simple enough for you to understand?
@@Jtheman497 I really can't stand keyboard warriors who want to discredit people who TRULY work on this sh!t. I've had a valve break and send debris all over both banks before. Through a single plane carbed manifold on a 454 dragster. This dude has no idea how stupid he makes himself look when he decides to speak. Overlap reversion is a real thing.
33:10 is one of several reasons I enjoy watching Steve Morris. Earlier he explained the piston/valve overlapping as the piston is coming up and valve is still open. Then shows it actually happenin with the scope. I’m not gunna lie, I’ve learned a thing or few watchin his vidjas!
As a field service engineer for GM I have had a piston break, put in a complete new engine, when parts of the piston downstream in the exhaust, come back up on restart and hurt the new engine.
Ouch. Did the dealer make you do the re repair for free due to not properly diagnosing and/or repairing the initial repair? I only ask as I have heard dealers commonly do this to their mechanics.
WOW! Broken pieces of piston making their way out of exhaust port and sitting there waiting to do destruction to the replacement engine. Never heard of that one before.
I have. 4.3 v6 catalytic convertor break to pieces and keep running the engine.. Told em not to usey truck.. Assholes.. .took it whe I wasn't home. Destroyed the engine..
I appreciate your transparency and you take time to explain in so much depth that even someone that's not a gear head understand and show everything it takes to have a streetable 5 second ride or wagon
thanks steve for the attention to detail on everything you do. i dont think that there is another person out there that explains & shows the public real diagnostic finds & fixes. keep up the GREAT WORK. GOD BLESS
keep up the great videos and don’t stop showing everything going on. Helps all of us that are trying to learn. Also it’s awesome to give a company a compliment when there product works. Too many only mention the bad things never the success of products. I’ve had no problem with motion raceworks products as well.
Steve, you may want to clip a mirror on the end of the borescope. A piece could be imbedded in the cylinder head. Waiting to drop. Edit. Sorry, I made this suggestion without fully watching the video. I know you are more thorough than I was giving you credit for. My apologies.
Many years ago I worked for the Chevrolet dealer in Middleville and I was working on a 6.5 Diesel truck. The end of the glow plug had broken off while I was trying to remove it. I told my service manager that the engine would need to come apart to remove the offending piece. We argued about the damage that could result by running the motor with that big of a piece in there. I gave in and put new glow plugs in it. Imagine my surprise after it ran for a bit that I would find the glow plug tip laying on the floor right under the tail pipe.
Worked on a 6.2 that the glow plugs were so old some the tips had flared. The pieces broke off upon removal. Thankfully I was able to retrieve them with a magnet.
Dewey's like a ferret sneaking through that tiny opening. LOL As far as borescopes go, take a peek at the VEVOR articulating scope/camera. They're like 85 smackers and you can actually rotate the lens 180 so you can check valve faces when you don't have the time to pull a head..
Yeah, I have to say Snap on lives on the name. They are not spending money developing any new tech. Just charging way too much for old stuff. I would definitely check into other manufacturers EDIT -EVOR Triple Lens Inspection Camera with Light, 5" IPS Screen Industrial Borescope, 8X Zoom 1080P HD Split Screen, 10 LED Lights Scope Camera for Automotive, Plumbing(16.5FT)
@@j.sarnak1391 We rely on some of their hand tools but look to other bands that suit a particular requirement. They're spendy for sure but have to disagree on the development of new tech. Their diagnostic tools are used by technicians that earn a daily living with them. Cheers!
Steve,you take it to a whole different level,don't change your approach and manner of solving a problem and explaining thr how,what and why of it. Your wagon is super bad,top notch,I love it,and I do hope to shake your hand again someday. I really enjoy your videos,your shop is a dream palace,keep up the great videos. You were so gentle Dr. Procto with the turbo exam.
Sir you’re showing me what I want to see, Great job. Thanks for taking time out of your busy day to make videos for us. I’m a SBF guy so I’m really digging Kyle’s videos too. Thanks fellas nice work ! Be safe.🏁
I know a guy that runs a 454 Chevy, it dropped an exhaust valve, the majority ended up in the header, and pieces went to all the cylinders and made dents in every piston top.
I had a shop rag make it's way through an engine. The rag was in the intake to prevent junk from falling in but was not removed before the carb was installed.
Really amazing the tech that is involved in the "wagon". To be able to explain it so that most people can understand is even more amazing. To put it out there for all to see (even your competitors) is a breathe of fresh air.
That title made me think about the screw that hurt my engine from a throttle body a few years ago... I really like how motion welds their little screws so they can't back out that's what I've been running since
Okay you got the same throttle body as me it looks like if you don't have the updated ones where the screws are tack welded send them back to motion and they will send you the new updated ones ASAP .. Cleetus already had an icon throttle body screw go into his engine well they were testing the product when it was about to come out so they've been welding them ever since
Back in 1991 I had a cat-ass-trophic failure of #3 piston in my 440 Mopar at right around redline (6,200 rpm), and it was AMAZING the places the bits of aluminum made it into..the guy I was running stopped on the return road while I was waiting for a tow and yells "Dude, I think your whole engine just ejected out the left header!" Not the WHOLE engine..I spent a couple hours with a dental pick removing aluminum that was packed into my carburetor base plate... Ain't NUTHIN' an infernal combustion does that surprises me after that episode.. Glad your junk ain't hurt seriously...give 'em Hell at Race Week!
I saw a Craftsman truck series engine back around '08 that let go on the backstretch of Daytona that had a piston swap holes. It's amazing what can happen with so many pieces moving so fast!
Don't change, Steve. I really appreciate you showing us how everything works and what happens when it doesn't, that's one of the big reasons I follow you. Not many guys out there do what you do. I've learned a hell of a lot from watching you.
My mom used to have a 1974 jaguar v12. The engine is setup with 4 side draft carbs, 2 for each bank. The two banks are completely separate from eachother except for what they call a balance tube or something like that which basically a piece of roughly 3/4 steel tubing that balances the 2 sides as the name implies. One day the car dropped a valve seat in one cylinder. It got beat to pieces and some of those pieces migrated to another cylinder on that side as well as some pieces passed through that balance tube and took out 2 cylinders on the other side as well. Upon tear down only 1 valve seat was missing but 4 cylinders were absolutely beat to crap.
Just a plug for Snappy,that camera looks a lot better than the Snap On one I have,but I’m also looking at diesel pistons that are lookin in a black hole. Yes please don’t quit explaining what you are doing and seeing,it is very helpful,educational and I feel it helps me as an mechanic,take my time,look closely and feel good about my work,Thank You Steve 😊
Learn something new on this channel every time. I had no idea the valves opened up that far. Sounds like you need to be careful when you have the top off the intake, Duey might slip down in there as he did with Tom's engine in the back of that van.
Just for a chuckle, Steve. When I first came across your channel last year, you were talking about "Drag and Drive" without any real context. For weeks I was trying to figure out what was a Dragon drive, was it some kind of transmission or fancy differential. I finally figured it out and boy did I feel stupid.
We won severalraces with our SC1 (or C3, I don’t remember) Yates Ford NASCAR head, Fontana block, 18:1, mechanical methanol injected midget, AFTER an air cleaner screw came loose and passed in, and out, and back in, and eventually out of our motor. The top of thx #3 piston and combustion chamber looked like someone when after after it with a hammer and punch, but it didn’t care. The ring lands were solid, everything sealed, and it still made 350 N/A horsepower out of a 166cid 4 banger that also throttled really well, like a real wheel to wheel racecar should.
Steve don’t let the internet trolls bother you !! Love your informational videos always! You can tell they get to you sometimes , your a smart successful man , there will always be haters
I don't think it's the haters that bother him so much as those who think they know more than they do or just don't pay attention. I've lost count of the number of comments I see on his (and other videos) where people say "you should do xyz" or "use xyz tool" when he clearly has in the video.
I'm sure you have heard of them. But the boroscopes we use at work are super cool. The tips can spin and move all around by button on the controller. It's really awesome. Definitely aren't cheap though!
years ago i dropped the 1/4 inch nut some place, thought it hit the ground someplace,, motor sounds fine. it went down the carb and was sitting on the bottom of the intake and didnt know it, Made a run and it ate it, sbc, piston grabed it and slamed it in to the head, burried it in the piston and beat the hell out of the head and cracked it. that was the end of that weekend.......
Steve I have to say, you're a extremely humble man. I don't know how you are always so calm about literally everything. Your car is killing it, from your continual grinding and keeping after it! I can't imagine your front side can get much better. I honestly wonder if there is any data on the fastest 60' on a 3600# car?
Steve. If you ever need to scope something again there are ones that the head can tilt around using a control so you can see better. Tons of options on endoscopes.
Back in the late 80's I built a 68 Olds w30 rocket motor for my 77 cutlass supreme. I was fairly new to building as this was my 3rd ever. One of the main bearing clearances was at the edge of the spec but still good. Broke the motor in good n proper and had run it for about 3 months as a daily driver. That one bearing had moved just the slightest and the piston started touching the head so lightly the machine ring marks on the top of the piston were showing on the head but not hitting hard enough to flatten them out of existence on the piston. I probably would have never known there was an issue if the oil hole had not covered about half of the journal hole and spiked oil pressure enough to blow the fill cap off the motor and spew oil all over the windshield at 70 mph on the Jersey turnpike. It is amazing what something spinning that fast with constant air pressure changes inside can handle or even do to parts flying around in it. Glad your motor lives to run another day.
No need to split the housing on the TB. Slide shaft in, install throttle blade and tig into place. No screws. Sorry if it seems like im just running my mouth. Not my intention. Just seems like a stronger method. Would add rigidity to the shaft as well. Just an old man thinking out loud. I can take criticism, in fact, I'm looking forward to it! Have a great day y'all.
@richwood8650 its posible to do it your way. Only? even spot welding can deform the shaft. But thats the same for welding the screws. Second? now you have a fixed unit. If it get damaged its junk, trow it away and put a new one on. And you get ,,rough,, weld spots. Air passing wil start to swirl and flow less easy. But also this is the same for the welds on the screws.
@@henkoosterhof5947 No sir. No need to throw unit away. Only replace shaft and throttle blade if necessary. A small Dremel would make short work of removing. If using the proper materials and heat gel, I see no issues. As far as rough welds causing a disturbance, many people can weld precisely enough for this application. Under boost, I doubt you could find an issue.
Steve, your honesty, integrity and humbleness are never forgotten. I believe you have helped Motion raceworks to make their product that much better. Keep pushing the limits!
My old snap-on bore scope came with little mirrors you clipped on the end so you could get a good look around. It was always a little sketchy just because they could fall off but they were a nice tight fit. The camera was terrible though, mind you it was used when I got it probably 12 years ago give or take. Things have come a long way since then.
Yeah they used to have a magnetic tip attachment for those as I recall. We learnt very quickly that unless you put a bit of masking tape around the clip it would turn int a case of "The old lady who swallowed a fly"
FYI, I'm an old gear head, and I don't reace. However, I'm an engineer, and I watch your channel because your videos are interesting from an engineering point of view.. What is my area of expertice? I design industrial desalination plants throughout the caribbean. I also like watching you guys go fast.. Unbelievable how things have evolved in racing.
I can remember being about 16 years old and trying to figure out where the razor blade went.. if you rev it up hard enough it will actually just burn up whatever's in there. If you get lucky
Back in the 70’s I worked at a truck repair yard. A big GMC dump truck was in for a brake job and while we were working on it, the owner of the truck decide to do a tune up on the 478 CID v6. An hour later he asked if we had a junk box of small screws. Later when he started it there was a horrible clatter. So he gave it the full Italian tuneup and it suddenly got quiet. So the guy smiles to him self and declares victory. We had to wait a additional day for parts so we stayed late and pulled the head , which led us to drop the pan . Turns out the piston was broken all the way to the skirt. It probably would have lasted 5 minutes on the freeway.
The size of the cameras has really shrunk over the past 20 years with these things. A 4mm camera with light used to be well over 1K just for the bit on the end. A bit like the Infra Red temp guns. The first one i saw was back in the 80's and I kid you not they wanted 8.5K for it.
Steve they make a scope that you can turn the camera in any direction. Even 180 degrees to look back up at the head. Eric at SMA uses one once in a while . Might be a good investment.
My buddy lost a 1/4 cab nut down a stock 289. It moved from bank to bank without even driving it. Pulled both heads to inspect. You guys rock. Thanks for the video.
You can say you have a Special Angel that watchs out over you Steve Sir. After all i have seen You and that SMX go through in the past You can say you have a Angel that watchs over You and the SM Family. Hope you all at SME are having a great weekend
correct, the valves he put on it could not react fast enough, and it pressurized the intake tract when the throttle slammed closed, and things broke. this is why i asked the question back when he changed the valves out, will they react fast enough. now we know!
@95turbostang21 and that's why I could never have a RU-vid channel. He couldn't have been more clear about what broke the throttle body, yet here he is having to clarify once again because some dipshit went off half-cocked. I have no patience for that level of stupid, so kudos to Steve for his monumental restraint.
Some of the shrapnel transfer in Detroit Diesel two cycle engines I worked on just amazed me. Pieces migrated everywhere. Pretty cool that you avoided major damage.
I love your channel. I was a mechanic for 45 years, 30 at a bmw dealer. I dont miss the business but I do miss being around the cars. You are really fun to watch
Everyone loves your honesty! Don't change a thing!! BTW, Amazon has horoscopes that can swivel 180 degrees so you can go through the spark plug hole and look at the valves and head
