Pacific raceway tomorrow with new motor!

Dialed in an extra 0.5 camber in the front. -2.75 to -3.25.

Also raised rear ride height 0.125" and went from 8 degrees aoa on the wing to 7.

I'll see if this helps with the understeer I'm having mid corner

So track day today didn't go so well. I'm pretty sure I have a blown head gasket(s).

A few laps into the day, car suddenly snap oversteered on me. Thought I blew a tire or something then when I got into the pits, tires were fine. Walked to the front, saw coolant coming off my splitter. Pop the hood and coolant everywhere.

Upper rad hose connecting to the radiator slid off about 1/2" and some coolant was coming out of it. Don't 100% remember if coolant was coming out of the overflow or not. But I did see bubbles.

Did a coolant pressure test and found that the stock spring clamp on the rad hose wasn't tight enough anymore and was leaking coolant. Changed clamp out and all is good. Holds 17psi for more than 5 mins.

Drove around, boosts fine on the hwy, streets, etc. Thought to myself it wasn't the head gasket that blew and over pressurized the system so much to make the radiator hose slide out. Was relieved until I came home, popped the hood with the engine running and saw bubbles slowly coming out in the overflow.

New sleeved block by dan benson (say sleeves will never drop).

Freshly decked heads but they were repaired. Pretty much a polished finish on the heads.

Not sure of the finish on the block. Cometic .040 inch head gaskets. ARP 625+ head studs @ 110/105 ft.lbs

Cometic's to blame? Finish on the block wrong? Head repair wasn't good enough and bad sealing? Was fine at 25psi on the dyno for a few pulls but once I hit the track, 25psi for long periods of time made it go? No clue....

Only 1200 miles on the motor. Very frustrated!

I've always heard such mixed things about cometic gaskets.

^Me too, Some say the get burned so easily.. But I have cometic since 2010 (knocking wood) but the car only sees drag, 1/2 mile run events and weekend drivings with occasionally road race.

A very respected Suby builder I very well know only uses OEM gaskets.

There was some intermittent mis-firing at high load. I think it was my IAT sensor going as I've gone through like 3 of them in 4 years.

The mis-firing may have caused the hg to get damaged but I can't believe it was that easy.

This is the first time I used cometics because oem doesn't make anything thicker and now I have this issue

My previous motors had gone through much worse and never had a hg fail on me.

What IAT are you using? Is it the oem together with the MAF sensor?

Arthur do some more trouble shooting before you come to final conclusion, maybe do compression check? You just scared the **** out of me now because i have same engine setup!

Pretty sure it's hg. Bubbles coming out of overflow ain't good. Unless one of my rad caps are bad.

I parked car for dinner on my way home from the track last night and it started a little different from what i remember. Possibly small amount of coolant in cylinder...

I'll check upper coolant tank today after work to see if I lost any coolant with car sitting overnight.

That sucks man, it seems that is either the cometic gaskets or the sleeves..... I would say the sleeves since you were running custom age head studs.

That sucks to hear man, road racing is hard on engines! Kinda scares me to road race mine even though It's just a Peewee old vf39

Question for ya though, the other day I finally broke my 5 speed and I'm putting in a 09 6mt so it had the longer gears like your 07. How do you like them for road racing? Moreso back when you had the old 2.5? I'm a tad worried I will bog in 2nd out of corners with the longer gears?

You won't bog that's for sure. Depends what track you're at too. With a small turbo you're going to have a lot of torque down low so I wouldn't worry about it. The 2nd gear on pre 07 sti's was super short. You literally stay in it for like 1 second when you're driving on the street lol.

Yeah much cheaper. I don't know why they keep breaking. People say its from the vibration the element is subjected too with high air flow. Some people fill the base of the sensor inside with a sensor safe epoxy to prevent vibration of the element inside. Hopefully that will fix it so I don't have to keep changing this thing!

And sorry guys for all the posts. On my cell at work and can't multi quote lol

Head gaskets crapping out for no reason would be pretty low on my list of possibilities.

25psi doesn't seem like nearly enough to stretch headstuds, especially extra beefy headstuds.

If the engine didn't get overheated, then I think warped heads aren't likely and you're left with the sleeves.

What does "repaired" mean on the heads?

Yes, never overheated.

Previous pistons had a crown piece break off damaging the heads a bit. Pitting on the quench area on the head. The holes were welded and head decked to make it as smooth as possible. It turned up pretty nice actually.

I think there is a post of the pics a few pages back showing the damage.
