Please be patient, I should already know the answer to my own question but I like to get some good and valid opinion from experience people and Not just Furom Typical answer about internal.

I have a 95 accord ex sedan
I have h22 Dohc Vtec Turbo with Hondata s300. 9psi (at 7000rpm) all stock internal.
I drive my car daily, never get up to 9psi.

The problem is, when I start, it smokes really bad (Burning oil) after I left the car setting for 24 hrs.
After I drive the car for over 10 minutes, it does not smoke at all until I accelerate hard.

When I remove spark plugs, piston 1 and 4 looks wet, 2 and 4 looks dry.


My question is, Could this be Head gasket, valvle seal, pistons, or what? LIke to get opinion before proceed with repair?

 

leek down test will help Tell you why you are burning oil.

 

possibly the turbo needs to be rebuilt

 

thanks for the input. However I have stripped the motor apart. I know I was having an issue with the pistons but wasn't sure.

The problem are (not Is), Broken ringlands, tons of chipping in the cylinder wall, and warned pistons rings, so as U can see, it's multiple problems.


This is the reason why my car was burning oil, Not the turbo.

this is why people always said "Build with Sleeve on H22 turbo". People are Correct about that.

Now I know.

sucks about your h22 man... however, there are plenty of people running less then 10PSI on stock h22 internals that have no issues at all... on a "conservative" tune you shouldn't have had any issues either.

 

its all about the tune up to a certain psi ... after that you better bullet proof your block ... good luck with that
