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

[@Voltuh]

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!

[@ChrisSullivan69]

Thank you sir 🤝

[@shaun9156]

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

[@gilbertahsam643]

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.

[@wilbready]

Sounds like the lifter tap I had a month ago on my Ram 5.7 Hemi. I had 117k and the hydraulic lifter failed taking out the camshaft. I caught it that same day but the damage was done. I’m sure you found it early enough to save the internal parts. Great videos, Chris! ~WilPaul

[@snipersteve378]

Something in the valve train hope its a simple fix!

[@keithczerniawski]

That sounds about right and he put in the bio that he did find the issue at the end and it’s fixed, I think he said that anyway for now, but I’m loving the progress on this build. Easily one of my favorite underrated channels out there right now. Every car is one I own or one I wanted to own I unfortunately couldn’t afford a Cobra especially not a terminator one. So awesome and crazy the market value on these cars are crazy.

[@Turkey-Tickler]

Completely agree. Makes me wonder if those header flanges have a warp in them. They were pretty rough…

[@gilbertahsam643]

@Turkey-Tickler sometimes the gaskets are the reason and when the weather is cold they come loose after the engine gets hot. But this guy he's a wizard and will find the problem real quick.

[@CarpentersandCars]

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!

[@ChrisSullivan69]

Thank you sir 🤝

[@SVTVasquez]

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.

[@jlioi1017]

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 💪🏼

[@ChrisSullivan69]

Thank you sir!

[@MrCecilbag]

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

[@ChrisSullivan69]

Appreciate it+

[@Jkerb720]

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 👍🏻

[@bobbydouglas16]

yup

[@Peter_Gozinya_]

Damn just watched the most recent video and this guy knew exactly what was wrong lol

[@jacobwaters5845]

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.

[@ChrisSullivan69]

Awesome!

[@stephenblanco5872]

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 .

[@ChrisSullivan69]

It's a rollercoaster of emotions lol

[@juliomora7353]

@@ChrisSullivan69 can only imagine. Love your videos and teaches most of us the challenges it comes with building an engine. Hope it’s an easy fix tho. 💪

[@TrendyBromando]

I can't even imagine the butterflies on an engine build like this... I do big car stereos and its always butterflies before the first test but its nothing even close to an engine build! Respect to all engine builders out there its not easy

[@Bazarre27]

Been binging this blue cobra series. Knowing from the thumbnails of future episodes, I'm curious or interested in how you keep motivated and not demoralized about the upcoming issues. Great channel, I enjoy the content and the flow.

[@01Snorky]

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

[@NoSleepTilGitmo]

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!

[@ChrisSullivan69]

Hope so!

[@thesearch9048]

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.

[@ChrisSullivan69]

Can't all be sunshine and rainbows lol

[@SicilianSVT]

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!👍🏼

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.

[@ChrisSullivan69]

Fingers crossed!

[@MrMulli0303]

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.

[@acrocketsfan]

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!

[@ChrisSullivan69]

Appreciate it!

[@Nitroxdude]

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!

[@ChrisSullivan69]

Appreciate it bro 🤝

[@Wraith-tu3ri]

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.

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.

[@jeffedmisten6576]

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.

[@babaoreally8220]

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.

[@ChrisSullivan69]

Yes proper coolant bleeding is critical on these 4V engines

[@calebjefferson7639]

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!

[@Lethal_Venom]

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

[@MrShawnsvtconv]

Fo a guy who is not a professional technician. I must say you did a great job. Especially with timing that engine. Im a ford master tech and I have seen people in my dealer improperly time 4 cylinder engines! My hat comes off to you

[@ChrisSullivan69]

Thank you 🤝

[@romanthecobraguy]

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

[@alexdavis6566]

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

[@brummy444]

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

[@celsogarcia1882]

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

[@ChrisSullivan69]

🤙🤙

[@chevyracing1080]

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.

[@ChrisSullivan69]

Thanks. Not really the case here though. It's a brand shortblock from a reputable local machine shop and the issue isn't anything to do with that.

[@justin.c_svt]

I look forward to all your cobra videos. Hope it’s just a top end issue. Maybe a roller or hydraulic valve lash. Keep up the good work.

[@ChrisSullivan69]

Thanks 👍

[@superbeeblaze]

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

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

[@jeremyt6234]

Build series has been pretty sweet.

[@jarrodhopkins4521]

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.

Sorry to hear that tapping noise but you're the man and will get it right in no time...hopefully it minor fix. An off topic subject...get yourself a snow broom.

[@bonecrrusherSS]

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.

[@ChrisSullivan69]

Damn it could have saved a couple hours lol

[@bonecrrusherSS]

@@ChrisSullivan69 yeah man - no more horrible leaking cap. Plus the red plastic looks horrible against my engine bay. Funny thing is - I am actually using a Mustang Moroso tank where the stock battery went. It clamps down using the battery tie down. I moved the battery to the back and had the tank powdercoated black so its a super clean under hood ice tank now.

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.

[@brian2359]

Jesus Chris! All that fantastic work to have a tapping. I’m guess a rocker popped off, probably popped loose when you were spinning it over before it built oil pressure!

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.

[@AlexPerkins252]

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.

[@alexvogel370]

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

[@ChrisSullivan69]

Ain't out of the woods yet lol

[@_Machine631_]

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

[@TheBBodyBuilder]

Chris my heart sank when I heard the tapping sound…almost sounded like something snapped…is it a timing chain tensioner? Hope it’s something simple and inexpensive. Love your attention to detail…you did an awesome job resurrecting the Old Cobra.

My first thought is lash adjustment but either way man you definitely kick ass don’t let it get you down. Keep the end go on site and I can’t believe you didn’t run it on the engine stand or take it to a dino before putting it all back in the car.

[@Joeybot]

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

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

as many have said, its got to be top end, to me it sounds like a big exhaust leak so something with that valvetrain maybe. you would think it would take much longer run time and abuse to get that loud of a rod knock (unless if engine was assembled without a bearing which very unlikely). good content man, i miss my cobra, thats what brought me to this channel

[@RayRyan1123]

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.

[@MrSmokin04]

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.

[@midnight347]

Lots of guys fun 5w30 on these without issues. The newer 07 up gt500 have Ford gt heads so they take 5w50 stock I run 10w40 in mine without issue at 750 rwhp. These engines were spec for 5w30 originally only reason Ford changed to 5w20 was emissions and mpg crap.

[@GameOver321]

Cant tell you how much i love this series. Sound like a wrist pin, had that on my 03kb cobra. I could 100%be wrong. Could even be exhaust leak. Either way, the car couldnt be in more capable hands. Good luck, can wait to see the diagnosis. Man you really dodged a bullet with that 10mm bolt in cyl 7!!!

[@ChrisSullivan69]

😅

[@bigshots27]

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 !!

[@WildcatWarrior15]

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 🤷‍♂️

[@Kingdominspirations-y6t]

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

[@ice44567]

I think you'll be alright, the noise got worse as the engine warmed up and oil pressure decreased a little. My vote is a rocker that wasn't properly installed, or some kind of restriction in part of the head's oiling where the offender(s) reside. Hopefully the cam is okay and you're good to go!

[@ohpigzz6029]

dude that killed me i was so hype for that to tap you got it chris no need to fear

[@anonymous..-]

I was relieved you found it on the top end.

[@svtpower03]

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.
