Blown valve or oil seal? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Well today I started my redtop sr up, let it idle for a few minutes then left my house. I get about a block away, I'm in 3rd going about 25 and I hear a popbam! and a cloud of blueish whiteish smoke comes billowing out of my exhaust. I limped back to my house to inspect it. The smoke smells like gas and now it wont start at all.

Any ideas?

Well I started taking it apart...there seems to be gas/oil in the #3cyl only because the plug was wet. Theres also a bunch of oil in the exhaust housing of the turbo.....

does it knock when running?

Do a compression test

Check turbo

figured out the problem, it was the piston rings and a valve seal.
