leak in back of head causing low pressure?
There's also a oil leak all over the starter.
I bought a oil pressure gauge(autometer electric) and i found out that my car gets only 25psi of pressure and drops slowly to 20 when its warm. If I rev the engine up, the max it would go is 25psi.
I took my motor out and going to change the oilpump and inspect the bearings and replace them and the rod bolts to see if anything is damaged. But could this oily portion of my motor cause it to leak pressure?

Tracer makes mine, and it's been a lifesaver.
As far as your current issue, I think you two. 1) I think your oil pump is on its way out - I honestly don't think your leak would cause a drop in pressure like that, unless you're spewing oil everywhere as you drive. 2) You need to inspect your oil sensor inlet, and all around the manifold for leaks.
Hope this helps,
Vince
