I have a 99 GTP with 124xxx miles and it leaks a bit of oil.. Nothing terrible though. But i've noticed it getting worse recently and now its smells as i'm driving for the first 10 minutes or so and on short trips like to work and back, i'll get home and smoke will be coming from the bottom side of the engine.. I was told it was just the oil pan gasket leaking but it seems to be worse when sitting on an incline and the last time I was under it the whole backside of the engine had oil on it so that makes me think valve cover gaskets.. Any ideas?
