Hey any help here is greatly appreciated... I have a 1988 toyota pickup 4x4 that has no power and when i remove the oil filler cap smoke pours out of it. it has the 3.0 v-6 with a 5 speed tranny. not too sure whats wrong. I bought the truck as is. I tried running it without the cat because i thought it was plugged. Right now i took the air filter tube off and oil drips out of that. The engine is fuel injected and has overhead cams. Please help me!!
