Exhaust valve was stuck open the other the day, i took the head off and cleaned out some carbon build up on the head and valve. Valve works fine now but now i have exessive smoke and it's blowing some oil out the exhaust. any help as to what it could be. it was running fine till the exhaust got stuck open.

 

it's blowing oil out the back??? as in you can see it.. or only if you put something in front of the exhaust?

 

if you place your palm behind the exhaust you see the oil on your palm.

 

you probably damaged a valve seal or valve guide when you had it apart

 

Or the rings are shot. Excessive carbon on the valves was probably caused by deposits from previous oil consumption. Do a leakdown test to determine. I say it's the rings.

 

Thats right..I would lay money that you need to change your valve seals and guides on both valve..just dont do the one that is bad..there cheep to do..and you can do it yourself..So change both..and i bet you your prob will be gone..
