My compression test

[alundra]

Hi,
After a fresh rebuild (Nissan head gasket, head verified for skimming or not), my car smoke some white one throught exhaust.
So i check the compressions (motor on heat):

cyl1:

cyl2:

cyl3:

cyl4:


In order to fix if the turbo leaks some water in the exhaust, the water line which feed the turbo return to intake manifoild.

Still smoke, at idle, at middle throttle.
I notice some smoke -grey- in exhaust gasket area (head/exhaust manifoild? or manifoild/turbo?)

No shaft play at left-right a few front-rear about my stock T2.

What do think about?
P.S: i'll order sooner some nissan exhaust gaskets, any better one?

how much running in time/miles has the engine had since the rebuild?
when i built my current engine with pistons and re-bore etc, it did smoke a little to start with whilst it bedded in. also there was some oil to be burnt off that i used to lubricate all the internal parts when re-assembling the engine.

it soon settled down and stopped smoking as the rings etc bedded in

Less than 5kms

might be moisture in the exhaust

Why did you rebuild it?

[alundra]

Thanks guys for your attention.
Head gasket blew after a track session.

Where did it blow?


Is the smoke oil or water. Put some tissue over the tailpipe and then check the residue

Between 3rd and 4th cylinder exhaust side, in the thickness of the headgasket.

mine went on number 3 cylinder, but i think the head was'nt true.

both enigines ive had have blow 3rd to 4th must be a weakness, also on my thread martin said that No.3 is the hottest of the cylinders, so more prone to detonation, rather than blowing hole in piston, it prolly eats away at the headgasket instead.
