Well I am still leaking oil even after I did a head gasket. I am thinking that it is the oil press sending unit as the leak is coming from the back of the engine. What else could it be I don't want to just start replacing parts and it still be leaking. Also when I did the head gasket the guy at the dealership said don't worry about getting new head bolts could using the same ones again be causing this problem?

If you can crawl under and look at the back of the engine, if you see oil from the HG down you know that it is the HG, if it is avove the HG it could be the oil press switch, or if you are turboed it could be where you taped for oil to run to the turbo, or it could be the valve cover....

I had an oil leak right before I blew my engine, I didn't have a catch can and it was comming from the blow by out of my breahter filter.

could be the crank shaft sensor. mine is leaking and i've already had the hg done. i still haven't changed it, but if you look at the back of the block, it's on the right side above the oil filter. you can just reach up with the car lifted and see if it's leaking.

Well there is oil all over the back of the engine and fire wall. It is also on my exhaust like it sprayed that way or something. I know it is not the valve cover gasket but that us all I can eliminate from the choices. Any other info ideas?
