Question about Jeep Grand Cherokee
96 jeep laredo 4.0. replaced plugs, wires, cap, and rotor. code says cylinder 5 missing, some knocking. going through about 1 qt. of oil a week. it's definitely leaking oil from almost anywhere possible.
If you are pushing oil out everywhere, and it's knocking, first check the pcv and vacuum hose (or ccv) if it's clear, I'ts likely you have a serious engine problem...likely a failed bearing, and possibly a piston problem as well. Check your oil pressure and do a compression test to se what's going on in there.Since #5 is showing a code, pay attention to what you find in that cylinder.
