LS1 Leak

I have an oil leak somewhere by the valley cover/oil pump cover. Im not sure what it is. I want to get rid of all my oil leaks. I have some pics of the oily engine. Any suggestions at what it can be? Thanks

Doesn't look bad.....almost looks like dirt and grime.....but I'm sure if you say its oil, it is.

I would hammer the entire area with a good degreaser and get it shiny clean everywhere. Then drive it for awhile and see if you can better locate the source of the leak.

If you can find Formula 88....that stuff is amazing. Cold engine, it'll shine. Home Depot has it here.

Can it be coolant? It doesnt look like coolant but my oil never goes down, but my coolant does...

My bet is a coolant leak, like stated above clean it up really good and drive it for a bit, then re inspect

Are those coolant lines that go under the throttle body?

Yes.......coolant lines coming from the headers and they meet at that rubber hose, then go over to the radiator right under the filler neck.

I would clean everything. Then tighten down those coolant line bolts on the heads and maybe even snug down the valley cover bolts...can't hurt. Also, change that factory clamp on that rubber hose for a screw type clamp.
