Discuss LT1 Horrible Leaks out of nowhere!!!

[TheBoss]

Hi everyone. let me start by thanking you for taking the time to read my post.
I have a 95 z28 a4 car that has just hit 90k miles. Around 10k miles ago I had engine rebuilt not because of a failure, solely for performance. It was bored 30 over, eagle 4340 forged steel crank, srp pistons, eagle 6 inch rods, Afr 195 cylinder heads and lt4 intake. also was full balanced and blueprinted. car has all arp hardware including head studs professionally installed.

Here is my problem. Last weekend at the local 1/8th mile dragstrip I was on my third pass and shifted the car around 7600 rpm. Ran a 7.45 btw all motor baby. lol. Anyway when I got back to the pits a buddy informed me that the car smoked a little during the pass. I figured it was a hose or something that came loose. Anyway I started it up and drove home everything was fine. The next night I took the car out and noticed smoke coming from the edge of the hood right at the windshield when I stopped at stop lights. When home and popped the hood and was horrified. Every spark plug was soaked in oil. ALL 8!!!. Also on top of that the engine was soaked with oil around the base of each cylinder head. Lastly and best of all there is a 2 inch wide burnt brown stream where coolant has been running down the block right between the cylinder head and the oil filter on the driver side. BTW my car no longer has the oil cooler. Have any of you seen this much of a catastrophic head gasket failure all at one time? I mean every plug was soaked in oil. 2 weeks ago this engine was clean enough to eat on now I feel like driving the car off a cliff. Should I just pull the whole engine and start saving for another rebuild which I cant afford for awhile???:
Any advise would be greatly appreciated.

Have u spoken to the builder of the engine u mentioned professionally installed do they back there work up and u don't have to save for a rebuild you'll need a set of head gaskets for sure tho but not a full rebuild

[TheBoss]

Yea I called him yesterday and he said I must have ran it so hot that it baked the gaskets and warped both heads but the engine has never been over 190 degrees since rebuild. I can take it back to him but I will be paying full price because its been 2 years since he did it.

[Scrub88]

Well I wouldn't take it to him if u just need top end work and your positive your heads popped wich sounds like they did . And 190 isn't hot at all . 3 passes at 7600rpms what head gaskets did he use

[TheBoss]

he said mls but from wht i can see from the edge of the heads looks like a black paper type gasket.

[Scrub88]

If your capable of doing it yourself it be a lot cheaper . Just get your heads checked/decked and some high quality head gaskets . It's not the easiest job but worth not paying a guy the price of a motor build has your oil and coolant mixed ? Milky oil

[TheBoss]

no mixing of any fluids. only smokes alittle white smoke on cold startup. however is loosing coolant pretty quickly and like i said there is oil around the base of each head and water has been running out the driver side head at some point. I just cant understand how this happens to both sides at once?? any engine builders on here seen something like this before?

[Scrub88]

Over rev can kill a set of gaskets bottom end built to take it but the gaskets protested

You sure?

Did you drain ALL the oil and inspected it?

I think you better.

Your builder gave you zero warranty?? How many miles since the rebuild? How did you pay?

[TheBoss]

Yes I just drained the oil yesterday and it is clean. Also I talked to engine builder again and he is convinced that whatever happened was my fault. Its only been 10k miles but most of those have been over 6k rpm. Also its been 2 years since he put it together. I think me and my brother will pull the heads off tommorow and get a good look at the head gaskets. I didnt mention the car is 11:5:1 compression. Ive ran it on a mixture or 93 and 110 nearly every pass at the strip.

Be interesting to see what type of head gasket he used I'd also check the torque specs on the heads before u loosen them up just to see if they are close to spec or looser than they should be

I agree with this, for head gaskets to blow that bad it sounds like someone didnt torque the bolts down, as many head bolts as we have This shouldn't have happened.
