Great Great video!This is what young racers need to see what it takes to run a on a buget and not just being on a buget but getting your hands dirty and doing the work them selves most young racers would just take it to a shop and have them do all the work I love seeing this as always second to none JOHN TURBO GREAT VIDEO keep the awesome video's coming look forward to them good luck on the heads
Proof is in the pudding...you go damn fast for working on a budget and making do when you got to...hell that video I seen you gluing two main bearings together I thought would never hold...it did...and went damn fast too...so if you say it will work...I believe....
Now if you have my up most respect for being as fast as you are with your backwoods repairs on your engine. This is what makes it a great sport is the ingenuity that goes into the repairs
You guys definitely get it done. On a budget no less. It could have been a flawed valve. Or it could be fatigue. They're only good for so long when you are running extreme. I wouldn't run even decent stainless valves in a high rev big boost motor more than two seasons on a shoestring budget. This channel is the best, I love the level of competition. Man oh man you make competitive runs most of the year. Fast as hell and the chassis is dialed. Other people have to get involved. Racing is expensive but it can be done at top level wisely. Turbo John and his crew are as impressive as it gets for a team. You have guys spending 10 times as much that can't be consistently fast. Or fast at all.
Great video John, it's easy to replace but to repair is better. I have been an auto tech for 30 years and it seems today some people have forgotten how to repair a head just go buy one yea right lol just wanted to say the seat line on your valves looked good nice to hear it explained 👍 Best of luck !
Weld'em up and repair them until they are used up and don't seal anymore, then glue them on with JB weld, and run them again! Haha!! No point in scrapping them if they can be repaired!
With the intake valve gone the next intake stroke of the next cylinder sucks the shrapnel into the intake then it's free to go down any cylinder until it's shut down.
I have a set of aluminum hemi heads I needed to get checked out, took them to company X to get them checked out. Company X said they were junk and I'm thinking aluminum heads can be repaired. These were the first set of aluminum hemi heads from company X I guess they thought I was going to leave them with them. N0! HELL NO!. I got another company to look at them and found their wasn't anything wrong with them. I'm sitting here looking at your video and thinking to myself if anything was wrong with them I can fixed them myself depending on the damage. Thanks!
My mechanic recommended me to get a new engine instead of changing just the one cylinders head thats misfiring what do you think about what he told me ?
Great content as always! Thanks for sharing. John doc had a video where they went to TKM I think it’s called. It sounds like they can fix heads like this too. I knew you could weld them but never knew they would be still good enough to put boost on them. Always learning.
I’ll put money on. The seat fell out. Valve hung up. Piston took out the valve. I bet that’s what happened. Kinda what it looks like. Or the valve coulda said. No more slappin up and down I’m done and just snapped off.
I don’t see any reason why it would’ve broke the valve other than just bad metal. You know what I’m sayin, when the metal came outa the furnace it had a flaw. I’ve seen several different things happen to valves and H-beam rods because of a casting or machining flaw. Love how you all do your own work 💯
Really enjoy your channel. New Subscriber and love seeing your work on the Gen 1 SBC with turbo. Curious, what head gasket do you run with the block being o-ringed? Also, do you really run zero water in the block and heads?
Thanks. I run Clark solid copper gaskets. Only water is in the heads to prevent hot spots and cracks. This car is usually pushed to the starting line and after a pass.
These are cast heads right? Mind telling me what filler wire you used? Have a project I'm thinking about doing. Have welded up a cast LS oil pan in the past and it was very finicky with filler it seemed I think I used 4043 to start but it's been a while dont recall what I used to finish it 👍
Hey John question for you have some black stuff in my oil filter no shaving just looked like transmission clutch material the black stuff in the bottom of the pan in my oil filter would that be bearing material running king coated bearings.
He does exactly what i do used parts is best i can swing stuff is to expensive these days..been 5.40s on all used stuff 2 years still going strong...knock on wood
I don’t think the valve was the cause of the problem. From past experiences I would would say the insert dropped giving the valve no choice too either bend or snap. Just a view from an ageing mechanic that spent a bit of time engine rebuilding, wouldn’t hurt to get your head repairer to give the other inserts a tap test to see if any others are loose. May have been a bit hotter in that cylinder? Injector ok? Thanks for the great vids have been a bit time poor to be able to watch them of late, keep up the great work.
It's insane how parts go flying in the engines when something brakes. It had to have gotten pushed back up the port then sucked down. Imagine when they brake at 7000rpm. That piston is going up and down 116 times per second..........That's crazy
Valve breaks on the intake stroke of the bad cylinder, immediately followed by, what should be the compression stroke. With no valve (it broke) it just blows the air back up the intake tract taking the debris with it. That air, and debris is available for whatever cylinder is on its intake stroke to ingest. It’s actually a bit more complicated than that, but that’s the basic idea. Hope that helps.
I’ve seen crazier. Like piston and ring stuck in the throttle blade threw a LS3 intake. At full throttle. You kill one cylinder. You usually kill at least 1 or two more from the debris.
Oh man. I just threw up a little into my mouth. Sorry John but I did. I tried to keep it down but...the seal between my stomach and mouth failed and ain't no amount of tig gonna fix that seal. Fuck if you had a Hemi, I'd send you a set of one of our old heads for free. Straight honesty. We have two older sets from BAE that we upgraded from that we're never going to use again and I don't have the energy to play fuckery with turbobullet and shit so they're sitting in sealed bags in our parts room at our shop.
Hey big guy sorry to be a bother with questions but would it be a good thing to maybe bite this situation in the butt while u have it apart a d put some manley hd valves on intake side and a good set of titanium valves for exhaust side (best for heat and boost) and maybe a good set of nextek springs and some stud girdles? I dont remember if you said you had a nasty cam and if it was a roller or solid or hydraulic but figured maybe throw some good valves and springs in it repair the head valve guides and valve seats put it all together and it should be rock solid and reliable for pass after pass after pass of 40+lbs from that big 102? Just a question is all please dont take offence I am trying to learn still and we had a BIG roller with a 4-7 swap in my nova and a decent set of girdles and we only had to adjust valves about every 4 passes and most of the time only a few actually had to be adjusted it i know it's a diffrent beast then the ls based engines but just a thought while you had it out bto have a good day
These are pac 1226 springs, it’s a solid roller with a little over .700 lift so it’s not too radical. Luckily, I don’t have to adjust valves often on mine. Now Randy’s is s different story!
That's what size i have in my aluminum brodix heads and i had to put titanium valves in them because the big roller cam i had with all that spring pressure mushroomed the top of my valve stems and i didn't want to go with the titanium caps so i just bought the valves
Hey John question for you have some black stuff in my oil filter no shaving just looked like transmission clutch material the black stuff in the bottom of the pan in my oil filter would that be bearing material running king coated bearings.running e85 for fuel and 20/50 oil
This is exactly what young racers need to see. Demystify head repair.
I am 23 👍👍

Great info.Especially for those of us that aren't made of money. Thanks again TJ.
You repair is coming along fine John. Please keep us informed.
Cylinder heads roll down a mountain...
Turbo John: "We'll get them fixed"
Best comment ever. Lol
Yes, lol
God bless your heart, I would never look at that head and think it could be repaired...... but I'm not as experienced as you either.
You guys definitely get it done. On a budget no less. It could have been a flawed valve. Or it could be fatigue. They're only good for so long when you are running extreme.

The car God's will bless you with boost again brother, keep digging

So happy I found this channel. Love the content, keep killing it!
Thanks
This man deserves all Jon DOC subscription and money you need a Chris in your pocket lol
Big boost on a budget, love your attitude and knowledge keep it up Turbo John, following from Tasmania 👍
Thanks
Love the intro John!! Where we break em. Fix em and break em again. Love it
lol
Wow those heads been through a war
Our budget does not allow it lol, love your videos, I learn a lot.
Weld'em up and repair them until they are used up and don't seal anymore, then glue them on with JB weld, and run them again! Haha!! No point in scrapping them if they can be repaired!
Great vid! Thank God for good welders!
Great update video John
With the intake valve gone the next intake stroke of the next cylinder sucks the shrapnel into the intake then it's free to go down any cylinder until it's shut down.
Need some tapper around those valve guides for support and flow

Did I hear you correctly when you said a piece of the valve stem wound up in the cylinder next to the one it came out of?
Yes, it was crazy!
That's an impressive amount of destruction, sir
That's what I was thinking? Just.... how?
nice boat anchor for the coffee table, Head bytes would fix em
Bro your fast as hell on a budget!
Thanks

It’s fun, and the only way I can keep it running.
Turbo John I’m the same way lol 🤣

I don’t remember the wire number, I’ll look on the box next time I’m over at the shop
I love the smell of race gas in the morning!
Hey John question for you have some black stuff in my oil filter no shaving just looked like transmission clutch material the black stuff in the bottom of the pan in my oil filter would that be bearing material running king coated bearings.
with the 18 degree heads ive always cut the guide down
1 butt whipe with thumbs down...why cant people just enjoy the free knowledge
They're probably screaming at the screen "BUT YOU NEED TO BUY NEW HEADS NOW OR YOU'RE WASTING YOUR TIME!" 😄

Thanks, that cylinder was hotter a few months back! I’ll get him to check!
John That’s a nice valve spring compressor. Who makes that one
I got it off amazon, but kegs and summit sell them also. Very easy to use!
Awesome video!!
Thanks
@@TurboJohnRacing you're welcome
I wish I had the time you have to devote to cars. So jelly
So your saying you have a small knock in your engine...
Good morning
John you are so destructive lmfao messing with ya bro it happens
Jhon what type of valve spring compressor is that, and where can i get one?
I got it off amazon, but summit and jegs sell them also. Very easy to use!
4:54 just wanted to know how the piece that broke off ended up in the other cylinder… trying to learn how I broke my car too 🤣 TIA
It's insane how parts go flying in the engines when something brakes. It had to have gotten pushed back up the port then sucked down. Imagine when they brake at 7000rpm. That piston is going up and down 116 times per second..........That's crazy
@@TurboJohnRacing that is insane to think about and it makes a lot of sense, much appreciated
Ide say no no no on undercut valves at those rpms and pressures. Im at half your hp used manly sraight ones on mine
How in the Hell does a chunk of valve end up in another cylinder???
Valve breaks on the intake stroke of the bad cylinder, immediately followed by, what should be the compression stroke. With no valve (it broke) it just blows the air back up the intake tract taking the debris with it. That air, and debris is available for whatever cylinder is on its intake stroke to ingest.

@@johngrabowski2957 thanks, I've just never heard of it before.

What is the ballpark price to get heads welded
Would probably cost 300-800 for all of it done, welding , surfacing, new seats, guides.
What kind of heads are those John and what specs
Profiler, 23deg, 210 runner
Oh man. I just threw up a little into my mouth. Sorry John but I did. I tried to keep it down but...the seal between my stomach and mouth failed and ain't no amount of tig gonna fix that seal.

looked like an old crack on the valve stem

What size are the valves in your heads?
2.08/1.60
That's what size i have in my aluminum brodix heads and i had to put titanium valves in them because the big roller cam i had with all that spring pressure mushroomed the top of my valve stems and i didn't want to go with the titanium caps so i just bought the valves
Overall, I'd say that head was in horrible shape. lol
Recycling at its finest. Its hard enough to weld dirty ass combustion chambers , so i don't think you did so bad.
They never get completely clean, but good enough to weld mostly
Hey John question for you have some black stuff in my oil filter no shaving just looked like transmission clutch material the black stuff in the bottom of the pan in my oil filter would that be bearing material running king coated bearings.running e85 for fuel and 20/50 oil
I have never seen that. All times I’ve killed bearings, it looks like diamonds/gold in the oil and pan.
Probaly black rtv from intake china rail so one ..ive seen that before
