how much does it leak? a couple drops or if you keep pouring it in then it pours out. Best way to find a leak like this is to put a piece of cardboard under the engine, fill it up, then you can see what part of the engine its leaking from, that is which side, then check out the engine and see where the trail of fresh oil is coming from. Oil pan gaskets do start to leak after they get old so that is a possible cause for sure. I couldn't tell you about any chronic leaking points on that engine though.
Our Father, who art in Autos, hollowed be thy frame. Thy Horsepower come, Thy torque be fun, in Imports as in Domestics. Give us this day our daily fuel, and forgive us our hooning, as we forgive those who hoon against us, and lead us not into chrome accents, but deliver us from rice. For thine is the Cam, and the Piston, and the Rod, for ever and ever. Or until they break.. Amen.
