I developed an oil leak at the back of the block and at first, I thought it was the oil pan gasket so I replaced the gasket and also checked the oil pan with a straight edge. It is still leaking but only when the car is on and motor revved.

Is there anything on the back of the block that can leak over time? I checked all the fittings before the motor went in so I know that isn't the problem. I'm going to replace the oil filter just to make sure I didn't get a defective one.

Anything else I can check?

Was it leaking from the oil filter?

Check the Pcv chamber. Its a black box that connects to the back of the block, its purpose is to re-circulate blow by gases from the block back into the mainfold to be consumed.

make sure your old oil filter gasket didnt stick to the block, what motor?

Check the oil pressure sensor location.

Good call. I found that my Oil Pressure sensor was cracked and leaking.

Thanks.
