Some of you already know that I blew my motor last week, and some of you wanted to know how or why it happened. After some inspection and discussion, we think it was the head gasket and studs. The gasket stretched out and allowed coolant to mixed with the oil and in turn break the oil pump. So all in all we are going to see if we could put the engine back to stock if the cams haven't created to much damage, or I'll buy an EVO 6.5 motor w/ turbo and make it work and go from there.

 

Sorry to hear that. Can you answer a few questions for us?

Do you think it is the HKS 264in/272out that did it, or you think you should've upgraded your retainers and springs as well? Were you floating the cams?

Did you have a raised rev limit?

How hard is it to change the head bolts?

I am planning a to upgrade to an HKS/JUN valvetrain and raise my rev limit up to around 8500-9000.

Thanks!

I hope you get her running soon!!!

 

How much boost were you running on it?

 

I was running 20 psi. To change the head studs is pretty much like changing cams. No I don't think it's the cams but just the fact that I didn't upgrade my head studs. As for the other questions, I'll find out for u.

 

Hey! Thanks for the answers, but where are you around here!

Did you raise your rev limit? Also, a member here was talking about changing the rod bolts as well because when they were diagnosing his engine when it was getting rebuilt, they seemed to be strained as well.

Lets spank those STis!!! ( I bet you they'll like it, which is why their rear ends are so high off the ground !!! - sorry, had to let that one out ).

 

Wow that sucks...sorry to hear. A good reason to consult a really knowledgable 4G tuner...

wtf bill!!???

i thought your car was all fine and ran some sweet times at the track!!??

dang! i also saw you scratched the side up and wing pretty nasty...

so you're f.c.u.k'd then.. u gotta get a whole new engine!? g'dang!!

sorry to hear it man, it was such a sweet and fast ride bro!

i'm starting to think it's actually good that i'm not laying down so much power yet.. so i can get these "insurances" (as big all calls em) taken care of first!..

c u around bro!..

Please keep us updated on the status of your engine. We hope its not too bad.

The STi **** are going to have a field day on this, but you did push the motor a lot.

Also let us know if the rods are forged!!! (So we know if we need to get the forged pruven ones in order to keep the boost at 22psi, with a stronger valvetrain of course!).

 

Badboy.. you know you can get your engine built how you want over at AMS as well, right?

 

I actually have a good friend who is a very good mechanic, but I will drive to AMS if he is too tied up. Well, I'll just drive up there anywayz too meet all EVO owners in the aera and check out their shop!!!

 

I wonder if detonation may have contributed to the headgasket failure?

 

I don't get the gasket stretch? It sounds as if the head bolts lost their clamp (stretched) and the head gasket therefore leaked. I am suprised this would have happened at only 20 psi. The oil pump is a gearator pump and whether it is oil or water it is pumping it will still pump it, save the loss of lubrication. What broke on the oil pump? If you don't pin down the true cause of the failure then you may end up in the same situation again after fixing the car.

 

To replace the head bolts with studs is a bit more complicated then cams. You will need to remove the intake and exhuast to get the head off. You have to replace the gasket if you unbolt it.
You can not reuse a head gasket or head bolts. Studs are re-usable.

 

Like the rod bolt change the head bolts could be done in the same fashion.
Remove one bolt at a time and replace it with a stud/nut. I don't see any reason to remove the intake/exhaust system or a headgasket change unless i'm missing something?
