alright well my b20's actin up again after i just rebuilt the head after a bent valve issue. so this time now its idling rough just like when i bent a valve but dosent make any noise like it did before, plus the oil light is flashing on. but when its cold started i glows slowly then it starts to flash, and it spits out oil out the exhaust, or gas. and if i take off the oil cap there is a lot of air blowing threw. and runs very rough.


oh yah i do have a oil pres gauge and its around 50 but it may go up like 5 or 10 or down 6 or something with the idle.

 

um usually that oil spitting out of your exhaust has to do with pistons rings after reving up to a certain amount of RPMs it shoots out oil . but the rought idle idk what that could be to tell u the truth .....

 

blowby usually means piston rings, oil out of the exhaust also means piston rings

 

do a leak down and compression test and go from there

 

ugh i was afriad of that. cause its spitting oil at even 1k rpm. most likely is the piston rings are gone, but i duno about the rough idle

 

sounds like a hole in a piston.

 

anyone think it could be bad gas? how would i check for that.

 

bad gas no sounds like piston rings or valve seals seems like your getting blow by and the ruff idle could be oil on the plugs might need a rebuild

 

^^^ yah thats what im thinking now... ugh not agian.
