Compression blowing out the head? Need Advice Please

[F-1]

Well Guys… I guess I am still in denial… I went to a local cruiz-in and the car ran flawless.. It was only 5 miles away to I decided to Beat the Piss out of the car.. 25-27lbs of boost ZERO knock O2’s in the 800-820 range.. and the car never skipped a beat or neither did the temp gauge move off of 168… (beautiful night down here in FL 65deg) I must of did this a ½ a dozen times…. Yes that annoying noise was there.. not till the upper RPM range and over 20lbs of boost.. Even came a cross and younger kid in a new GTO with some work done.. He picked on me and I ruined his night.. (even skating with my 235 60’s on the back!)

If it is blown, it was blown at the track and I didn’t hear the noise because of my helmet…

Thanks,

Denial Dave

Update..

Update…

The noise to me seemed to be getting slightly more prevalent, so I got motivated and started taking the pass side apart..

I think I forgot to mention, when I re-torqued the pass side I was too lazy at the time to pull the header/turbo ect… off to get to the bolts.. I just did the top ones, because at that time I thought the noise was coming from the drivers side.. Driving it more now sounded like the pass side..

First thing I noticed when I pulled the Valve cover off was a small drop of antifreeze, see pic… The lower head nuts (after I moved the header out of the way) seemed to get some pretty good movement @ 85# torque… So I am going to loosen all of them and re torque to 85#, put her all back together and see what happens.. Wish me luck… With less than 500 miles on the Cometics, can I pray for a miracle?

What do you think??

one side note, do yourself a favor and loose the antifreeze. We're in Florida, dont get cold enough to need it. Just to to an autoparts store and get a bottle of anti-rust from prestone or such and go with that and water. Antifreeze = major enemy if you start a leak into the oil passages.

Let us know how it turns out. Were on the edge of our seats with our fingers crossed. Good luck...

I agree with losing the antifreeze...it will cause you more grief than it's worth...I have been running distilled water only with a little RMI mixed in for many years...AZ(where I live) is like FL...never gets cold enough to worry about the water freezing in the block...

The Verdict is in!!!!

Well Gentleman… The Verdict is in!!!!

Just buttoned her up and went for a ride….

I will now be a firm believer of re-torquing heads, (studs, no studs, gaskets, no gaskets who cares)… It is fixed…I guess it says a lot for the Cometic’s… I have had the boost between 22-26# on several occasions and a few hundred miles trying to figure out what the problem was, and they held together..

I am going to the track next Sunday and I’ll give her a beaten…for all the non-believers of re-torquing here is a good example..

Thanks for everyone’s input… I can now sleep tonight.. :biggrin:
