I have a leak between the oil filter housing/oil cooler/wtfever they call it and the block. I cannot find the part, or a listing for the part anywhere! Can someone please help, the leak is getting quickly worse, and parts stores show no listing either.

 

edit: it’s a 2014 express 1500 cargo van with the 4.3

 

The oil filter adapter? Rock Auto shows a gasket for this for under 5 bucks.

The adapter itself is probably dealer or salvage yard only

 

Check the cooler lines. Often the crimped ends start to leak, and then the oil runs down them to the junction.

 

I’ve never used them before so didn’t think to look there, I might be using them now though, thank you. Shipping is a bit pricey if you don’t want to wait two weeks, I guess it’s up to what the dealership tells me if they call back today.
