My chevy blazer k1500 (full size) is spittin out alot of oil but I cant really tell were. It is runnin rough like its missing. Seems ok when at an idle but when I put it in reverse it bogs way down and shakes and really wants to stall.I pulled all plugs, checked wires, they look ok.I replaced pvc valve. Nuthin. Sumthin is WAY wrong.1992, 120,000 Any ideas please!
Check to see if your pcv valve actaually works, there should be vacuum at idle. The hoses go soft on these and suck together on the inside. Check to see if your oil pressure switch hasn'tdeveloped a leak, it's by the dist in back. If you can't see the leak take to a car wash and wash the engine to see where it's leaking as well.
