smoking out breathers

[dodgee69]

hi was hopen u guys could help me out iv got a turbo 3.8 i started it up yesterday went 4 a drive and car started fillen up with smoke when i hit boost so pulled over poped bonnet had a look when i give it a rev smoke bellows out the breathers what could that be

[VN_Luke]

something is most likely burning a lot of oil, and that smoke is coming from the crankcase.


you could have a smashed piston, whihc would cause oil to burn via combustion...

you could have a spun big end bearing or something, causing a heap of heat, and then as it swings through the oil it cooks whatever it touches.....

first step to diagnose it would be to do a compression test on all the cyls and report back

I had this problem when i got it on the dyno, started smoking out the Breather on the rocker cover, then i blew a head gasket not long after it, or it was already on its way out, not sure if it still does it hope not.

Its either your valve stem oil seals or your piston rings are gone

[Bz Kn33z]

I think the valve stems where gone, i have put reco s2 heads on now. and havnt seen the problem, but will be looking out for it.

[delcowizzid]

also could be a line to the inlet manifold still plumbed in like the one under the throttlebody to the manifold will blow boost clean through the bottom end

[Bz Kn33z]

Yeah, i made sure i put a Bung on the T/B and then i just have a breather coming off that, but if the breather is off the Rocker cover it wouldnt be attatched unless he just drilled a hole in the Rocker cover cap and put it on there for the s1, s2 its on the manifold.

sounds like a head gasket.

[delcowizzid]

it is most likely they allways blow into the valley and smoke like hell

[Bz Kn33z]

Still got 154rwkw and i had a feeling the head gasket was letting go abit, not long after that it was dead. i think on my VID of my car on the dyno you can see the smoke abit.

i had i feeling it was going to be something along those lines im getin compression testd tomorrow
this wiil be second motor first one i blow both head gasets cracked two pistons and blew rear main seal

[delcowizzid]

does it have bigger injectors and a tune or it is allways gonna happen

doesnt sound good

I also blew the head gaskets on NO3 and it melted the Manifold gasket and then popped out the rear main seal, lucky no piston damage, that i know of
