oil leak

Asked by Aug 15, 2019 at 04:44 PM about the 2003 GMC Sierra 2500HD Standard Cab LB HD

Question type: Maintenance & Repair

I'm working on a 2003 GMC Sierra 2500 HD. It was leaking oil when It rolled
into the shop. I checked under and found it was leaking from the aluminum pan
that the Oil pan bolts on to. My question is do they sell that part of the engine
separate and if so how much would it cost. I tried looking for that part but I can't
get a description on that part.

Note the picture, that is 6.0L engine, long block, where is it leaking? Found the picture in parts book. Is it the timing cover that is leaking? Other than that, I can't think of anything?

The engine is a 6.6 liter and it has the smaller oil pan. Your picture doesn’t show the part I’m talking. The part I’m talking about actually look like another oil pan but it’s aluminum and the smaller metal pan bolts on to it.

The oil pan bolts to the engine block. Can you post a picture of what you're looking at? Jim

As you can see I took the oil pan off. The aluminum that’s left is where the leak is coming from “not cracked” coming from the top where it should be sealed. It looks like some one tried using high temp sealant on it .

Look at the oil pan for your engine on Rockauto.com, there's supposed to be a baffle in the oil pan sump. Could that be what you're looking at? Maybe this has been apart before and someone else didn't know where to put the baffle. Just a thought. Hope that helps! Jim
