- Q:I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.

- First off you are suppose to take your bike back to have your valves adjusted after 500 miles. Anything later can cause problems. The motor is already broken in. why did you wait so long to have them adjusted ? Your vibration is the tire is not balanced right , take it else where. good luck
