The Built Engine In My SVT Cobra is ALIVE But There's a BIG PROBLEM!! 

Engine: TAP TAP TAP Chris: That's not good! Hemi guys: First time?

It's a minor problem. Sounds like a rocker that out of adjustment. It's not a rod because you would know that sound. Another thing might be exhaust leak. But you are the guy that knows the best because you are the best of the best on cars. Have a blessed day and l know you will fix this problem.

I have a ‘98 cobra with 32k miles, and watching your videos makes me want to take it apart for no reason 😂 sick garage, sick cars, sick content!

Thanks for showing the good with the bad. Working on cars never goes as smooth as some other channels make it seem. I enjoy the long videos compared to the 5min to 10 minute videos that make it seem like the builds are just perfect and smooth. Hope it all gets worked out good luck keep killing it.

Definitely sounds like a lash adjuster failed and lost its prime causing the rocker to move. Should be able to lock in the chain with a timing wedge and remove the cam for replacement. Definitely a bummer after all of that work- appreciate the detailed videos 👍🏻

The 03-04 terminator is my dream car. This build was actually how I was introduced to your channel. You did an outstanding job! I don't know a lot about the overhead valve system but that has to be something simple. I could see the emotion in your eyes. I would have felt the same. Thank you for all your content it has been educational and inspirational!

Only thing more intense than the pre-first start butterflies, is the pit in your stomach when you hear that unknown tapping noise , but anything can be fixed , hopefully is something simple like a tensioner or rocker .

Hope it’s an easy fix for ya man! Car has came a long way and all your hard work is not overlooked. Always wanted a sonic blue terminator and love watching you save this one 💪🏼

Damn. After all that hard work, that's a hearbreaker. With all your attention to detail, that can be disheartening. Keep the motivation my man, it will work out. Love the content

You guy remember SPIKE TV on a Saturday morning,This is that good if not better ‼️

Nice work! Sounds like it spit a rocker though. The long format is awesome!!

Love the progress! Hope the tapping is something minor. Appreciate you showing the highs and the lows of a build. Lord knows something always goes wrong on my projects.

4V's are SUPER sensitive to oil weight brother. That sound is a collapsed lash adjuster (or two). If they're not Ford GT lash adjusters (which ran 15W-50 oil), you MUST run a 5W-20 (or 0W-20) because the orifice size in the Cobra LAs is too small for the thicker oil. I'll bet the rockers were about to come off...or they did which would cause a ton of damage. Swap to the thin stuff man. Sorry for the pain.

Sounds like a lifter, loose rocker or maybe timing chain? Top end. Good luck man

sometimes things happen, i know the issue will get fixed and we will be seeing fun videos of it driving soon. kudos to you my man can’t wait to see it running, my cobra blew the diff so we just got a built solid rear axle

Watching you work on your car motivates me to get my 03 GT back up and running. Picked up a mark viii engine and swaping that in.

You do great work. My heart is tapping with that engine, damn.

I’ve really enjoyed watching this build. It’s come so far from the beginning. Hope it’s an easy fix man. Can’t wait for the next episode.

The ups and downs of a new build can be frustrating for sure, thanks for keeping it real. Hoping you figure it out quickly and it's nothing bad, Godspeed!

The suspense is killing me.... i cant wait another week to see what was wrong.... Chris, Don't do this to us! We need the fix video immediately! 😂😂😂

Great build, hopefully the issue it has is an easy fix, looking forward to seeing what it is

Another great video Chris. Full confidence you get this corrected!

Glad i stumbled on this channel, been watching the build from the day you bought it. Hope its an easy fix and doesnt have to get torn back down. Great work all together including the vlog so we can see alot of progress each video.

The tapping/ticking kinda sounds like a lash adjuster or roller follower to me. I have a 5.4 and its got the same thing. Can't wait to see it on the road!

Awesome car, and i agree, it is not a rod knock and im sure you’ll figure it out quickly and get it resolved. I’d love to see more on the building of this car. Great work so far!👍🏼

Shout out to harbor freight for always having something we need for the right price and I like the beats you choose

Use a black Sharpie to touch it up. Easy. Love the videos man and keep it up!!!!!

I feel like Chris is what Captain America should have been 😂 I can imagine his routine: up at 6am, pours a coffee that lasts the whole day aside from him drinking at regular intervals, and rebuilds engines all day with sprinkles of dry humor throughout. The guy is clearly a superhero

Dang man. As a fellow car enthusiast, been there many many times. It's always something. Keep us posted and keep up the amazing work!! Your channel kicks ASS.

i would've relocated that battery.. anything beyond centerline of the axle leaves improvement.. ya did everything else

I could feel the defeat after being so meticulous on putting it all back together. It happens, hopefully just something in that valve train that makes itself evident. Great work so far

I wish I had an answer for you but after watching all your vids I am sure you will correct the problem. Amazing talent Chris.

Hoping it is a easy fix, great to see that beast back together again. Engine bay is looking very tidy indeed!!

It’s fortunate that you know that to properly fill coolant in these,they must be filled thru the coolant bung on the crossover tube with engine running and all air bubbles stop coming thru the bung.I would suggest a coolant temperature gauge in lieu of their idiot light.Installed a billet oil pump in mine,also.It was great that you mentioned and addressed all of the problems encountered in your install for us viewers to know what to learn from.You gonna have fun.

Love the way you go about getting things done. Keep the faith. One step at a time. Good luck with the troubleshooting.

Man all your hard work and dedication is so much appreciated you have no idea , all the people watching this build taking this roller coaster ride of ups and downs , all rooting for you man in hopes that it all turns out good for you , really have this beautiful machine looking amazing! I my self just sold a built 03 Sonic blue terminator hard top few months back , and watching you work on yours makes me miss mine . Looking forward to the next video drop brother you have some amazing rides and putting in the long hours and hard work , after all that you can sit back and rest up and admire all you’re awesome accomplishments in the garage ! Rest up brother!

ME AND MY FAMILY WATCHING, LEARNING AND ENJOYING YOUR NEW VIDEO CHRIS❤❤GREETINGS FROM SONORA MEXICO

love the content brotha, also love that your inner teenager shows drifting around in the snow having a blast!

Watched the whole video, just coming back and commenting that i I'm waiting for the next video to see how its running. No rush, just can't wait

A realistic video Chris showing the highs & the lows.......you will get it figured out...keep up the good work

You will overcome this issue. It's this way in life...ups and downs. Love your channel. I've learned quite a bit just watching you. Keep it up!

That oil is waaaaaaay too thick. If you’re running 80+PSI at idle then the pump is already bypassing oil at idle flow. Thinner oil may fix the lash tick too.

Dr.!!!!! It's alive Great freaking job Chris Never doubt you bro... For some reason this cobra has me hooked on the built Looking forward on the next video

A Chris Sullivan upload? Today's gonna be a good day! 😁

Keep at it man. I admire your meticulousness. You’ll find the problem and sort it out quickly. Building oil pressure that quickly + s steady idle is a good sign.

It’s a bummer that the Cobra is tapping but I know you’ll figure it out! Excited for the next episode 🤘🏾

I just can't get enough of this great content/channel! 👍

Great job Chris I'm sure you'll figure it out you very good at it 👍stay motivated

holy cliffhanger lmao. Looking great. The tone of voice with the "ohh yeah, ok, oh my god" doesnt sound terminal so thats good.

I used to do a lot of work on cars with a friend and often talked about what it would be like if you had your own garage and could do work at home. What a dream you have there. I hope the next video comes as soon as possible.

Thanks for the update. Looking forward to the next one. Hoping it’s not a major issue. Peace out!

Love the content as always! My first car was a ‘94 z28 Camaro and second a ‘04 cobra. I had that same tape previously on my c5 z06 when my dad and I did a cam swap. Turns out one we forgot to tighten one of the pushrods and hopefully that’s all this is. Keep up the awesome work!

sorry to hear the tapping...you did all you could along the way..hope it's not too bad...thanks for sharing the good and bad with us...enjoy the channel...

Im on the edge of my seat. Need the next video Asap. Great content man.

Haven’t watched the whole video as of typing this just hearing the clip at the beginning, however it sounds like a top end tapping sound not a bottom end knocking. Best thing to do while you’re ahead is pop the valve covers back off.

Keep the cobra content coming🎉

The dreaded tapa tapa. You got this! Such a sick build.

I was smiling for most of the video, and then the end hits you in the nuts. Crossing my fingers it’s an easy-ish fix man. Can’t wait to see the next upload.

Really hope you can get that figured out. Wishing nothing but the best for you man. Can’t wait to see the next video.

Damn bud, what a bummer, i know you can figure it out and fix it, at first i was thinking a bad header leak, but it was not, seems to be in the top end, by your reaction at the end of the video, good luck Chris, hope it's not bad.

Excellent video!! The noise sounds high in the engine. Valvetrain, as someone stated below me.....😊

Keep on keeping on your determination always prevails. Good luck and envious you will have another Terminator! May have a rocker popped out they make that horrific noise with a new build.

Sorry to hear.....Keep on Keepin on. Love watching your videos. It'll all be worth it, right after I watch you button up the engine, detail and roll that sweet sonic blue out of the garage for some lucky owner after purchase (and a test drive:) !

I felt the feeling when she turned over! Never gets old! But man… that TAP… FML… keep your head up, doing great. Hopefully something simple

Love your videos - I had literally mentioned to a buddy of mine I would never put in an unknown to me engine that I didn’t proposition someone to build for me because of this exact reason. You’re basically rolling the dice it was done correctly.. great learning lesson here for everyone.

Sick rebuild , thanks for the content

You know way more than me , but I'd be draining that 15w-40 diesel oil straight away and putting in something closer to the specified for that engine. Good luck Chris , hope it is all good.

Glass Half Full: I guess that’s one good thing about OHC, you can access every bit of the valve train from under the valve cover and don’t need pull the intake manifold 🤷‍♂️

Love following the channel. Sounds like you found the issue at the end. I was first going to say it was a valve guide. These cars are bad with valve guides wearing . U need to replace them with bronze valve guides. I had that same issue. I have a full rebuild on my channel. GL

Build series has been pretty sweet.

Another masterpiece of a video. Keep up the great work brother 🫡

Love the content! Keep your head up! Hoping it is an easy fix!

Great series on this cobra! Hate to hear the valve train noise

Good job. Keep it up. Big fan of your work

Love this project, fantastic job on the motor. Can't wait for the next video.

I’m sorry you’re having those problems but I really do enjoy your program I know you’re smart enough to get it figured out I’m looking forward to more programs Thank you Mark Reid.

Thanks for always showing the good and the bad! This is the real stuff! We all run into problems

Great video! Valve train noise for sure….Something simple I really hope bro! Doesn’t diminish your work at all…..Great job as always!

Motion Raceworks sells a 12 bolt cap/flange for that intercooler tank. I replaced the garbage plastic cap for a billet/anodized black one for my 2650 setup on my c6.

I am looking forward to your follow-up video. Suspense can't wait to know if its Top end valve trai, hopefully just a rocker or broken spring. You do great work.

The teaser at the end, nice touch!! Had us on a cliffhanger…

Never ceases to amaze me how good you make these cars look🤌🏼

sounds good regardless. that just sounds like the typical 4v valvetrain tap. probably starved for oil.

I’ve just subscribed, watched all your cobra videos. Really enjoy them. Hopefully you fix the tapping noise soon. I was thinking it’s maybe a lifter or rocker

Keep it up man, you're almost there. Sometimes ya gotta take two steps back and then one forward.

Another great video! It sounds like a stuck lifter. If these are new lifters, then I would let idle a little longer to see if it primes itself. If it’s not a new lifter then I would buy all new OEM lifters, pre-soak in oil then install.

Watching from Louisville, Kentucky Sunday morning

My sister’s car made that same noise after a new engine, it was a 4.6 3V. The problem was a dead lifter/lash adjuster that wouldn’t pump up. Put in some fresh lash adjusters for the offending cylinder and the problem has stayed away.

Sounds exactly like a lash adjuster. I can’t remember if you put a new set of adjusters in but if not, get a complete set of 32 and new Ford “GT” cam followers. I think LMR might have a complete kit. Sucks now that the engine is in the car as getting the drivers valve cover off is a pain but on mine I just took the clutch cable out and lowered the k member and I just barely got it out. I have been there dude, with that exact noise. It’ll be fine just don’t run it anymore so it won’t beat up the cam lobe. You got her spanked though! So exciting it runs good !

Have a 99 cobra sounds like the slack adjusters(lifters for the mod motor). Had a light tapping when I bought it turned out the motor didnt like the 10w30 previous owner had in it. Switched back to the recommended 5w20 and they quieted down they dont like to pump up with the thicker oil. But hope you get it figured out, have enjoyed the build on the cobra.

Awesome stuff dude!

Another great video. That sound definitely makes the heart drop I’ve been there haha. Hopefully it’s a lifter that isn’t pumping up with oil or maybe a rocker is loose or even maybe fell off I’ve seen that before. Definitely sounds like a top end noise in the head.

Chris hang in there, outweigh the good vs the bad, if building an engine was easy, everyone would do it! I am sure its something minimal and once its fixed, you will be back on top. Id say before taking the valve cover off, scope the cylinders first to see if you can see any wear. Ill keep an eye out for the next video !!

Hope the issue ain’t bad man. Saw that you caught it already so fingers crossed 🤞🏼 Best of luck always

Damn, glad I stayed all the way to the end. Can't wait for the next video.

Def feel you with the first start up heart pounding feelinglol also Being that this is almost identical engine plan build i have for mine i enjoy the build and content and attention to detail! Keep up the great work man! Looking forward to next video

Love watching your videos buddy you really have been inspirational keep the videos coming

I was relieved you found it on the top end.

Hard to tell from the audio through computer but I was originally thinking it could have been a bum injector since it wouldn't be a collapsed lifter due to the whole not having pushrods thing. The fact that there is a preview of pulling the valve cover off makes that a moot point.

Your videos are so dope I’m always checking to see when your next video comes out I’m a huge new edge fan I have two of them a 2004 Mach 1 dark shadow gray and a black 2000 gt but even your other build are cool to keep up on right on man keep it up
