ok. so i just got my rebuilt engine on my truck and on the road and i've got a pretty severe oil leak - i've leaked about half a quart in almost 500 miles. there are three leaks - one from the front of the oil pan, one from the rear, and one from the oil cooler lines. the oil cooler lines i can take care of - no big deal. in regard to the oil pan, however... when i installed the oil pan, i used the gasket in my gasket kit - it was just one of those flimsy paper-like gaskets. i'm wondering if that's my problem. should i drop the pan and use silicone instead? it's frustrating b/c it's about time for it's first oil change (only got 50 miles to go) and i'm going to install amsoil - too spendy to be wasting on asphalt!
