head issues

[Onefast99gsx]

Does it smoke white at all?

How about oil on the dipstick, is it milky looking?

Those cylinders shouldn't be associated with one another at all. Air would have to bypass one set of rings, go into the crankcase, travel up to another cylinder and bypass its rings. My guess is the headgasket is shot.

I used a stock headgasket, and i sprayed each side with copper spray when i redid my head. Been holding up fine. Are you using ARP's? What's the most boost you hit with your 50trim so far?

ARP's, 24psi 111 octane.
oil is clean, coolant is clean

its probably blown between cylinders, even tho the car idles and runs just fine..
super weird.

Why bother checking it when it is warm? If it is bad, it is bad. Let me know when you get the head pulled off. I have only seen DSM headgaskets blow from the cylinder to a coolant passage (except for my metal one last year that melted out the back side of the head).

Did you TDC the cylinder right after the exaust valves closed or when the intake valves closed? If you try to pressure up the cylinder during overlap it will do what you are describing.

Are you sure you did the test on the compression stroke at TDC and not just at TDC?

[Enes]

uhm... stupidity at its best... proven..

not sure, i just got it to TDC and did it. yaay RTFM

Do you know how to check to see if you're on the compression stroke?

[Matt D.]

Hahah, oh man... Let's us know how that goes for you. :)

[Enes]

please advise on how to check to see if i'm on compression stroke..


;p

[Enes]

So how do i determine that Cyl1 is on compression stroke, ?
same should apply to #4 at the same time correct? or are they not at the same stage?
