My gsr turbo is pushing a lot of white steam out of the valve cover breather hole.
My compression test reads like this from diz. 90 / 120 / 180 / 120.
I get white smoke from the valve cover breather hole, and out of the hole in the oil dip stick. Very small white smoke from the exhaust.
No over heating, no bad idol, nothing different, only water level goes up and down on the reservoir.
does any one know what this problem is?

 

Possibly headgasket.. any white milky stuff in the oil?

Could be rings.. add a bottle cap of oil to each cylinder and recheck the compression. If the compression goes up, then your rings are fried.

But its definitely one of those.. Your compression numbers are too low and too much variance between them.. Are you sure you did the compression test properly?

 

the compression test was done right. i have done it before on other cars. its wiered normally there about 10 to 20 off.
i will try the oil on the piston compression. see what happens.

 

keep us updated

 

could it be a valve??? maybe its could be a lil burnt on one side, and just letting enough air around it to put pressure in the head??? just a guess... good luck

 

Well once he tries the compression test with the oil we will be able to see whether its the rings or not. If its not the rings then the only way to fix this is to pull the head off..

 

Im almost positive that is either the rings or the headgasket. Thats the only way he will be having an excessive amount of gasses coming out of his block/head

 

this happend to me on my LS/VTEC turbo integra. the stock pcv system couldnt keep up with the boost and the power the car was making so i upgraded to catch can and had the lines run from the back of the block, into the catch can, and then out of the catch can and back into the other port on the back of the block. it fixed the problem instantly, it was just a pain in the *** to have to keep draing the oil that filled up in the catch can.

 

ok heres the update, its a ring. maybe a headgasket, i need to replace it anyways.
i did the oil on the piston trick, and sure enough the piston that had compression of 90 went to 180, yea wow.
the pistons that were 120 went up to 160 and the piston that was 190 held.
akandok thanks a lot bro, good looking out,
rebuilt time, low compression pistons, rods, block guard. sleeves are too much for me.
