Hey guys, I have a massive oil leak on my Chevy 350. I can't find where it's coming from but it's on the front passanger control arm and engine cross member. I don't think it's from the timing chain or the pan, but where else on the from of the block?

There is a bolt that is supposed to be in the front of the block near the timing cover that seals off a threaded hole going into the fuel pump push rod inside the block. I've seen these loosen up and leak. Also check the fuel pump and fuel pump mounting plate gaskets. Good luck.

This oil leak came after I got on the motor pretty hard, what could've caused that?

That sounds exactly like a pan gasket leak. Try to clean everything up as much as possible. Scrape, then brush with hot Dawn soap solution. After that dries off spray everything down with a couple cans of brake cleaner.

That will give you as dry of a surface as possible to verify where the leak is actually coming from. Good luck!

Possibly pressurizing the crankcase with blow by?

Pam gasket, valve cover, is there a breather on that side valve cover? Any senders on that side that could have blown out?

On the passanger side the valve cover only Has the oil add hole with no breather, driver side has the breather. My motor definitely burns a little oil and I know it has some blow-by. I'm going to take a look today, I was so tired getting home last night I didn't even take a look. But I think it's is the pan gasket.
