Cast Aluminum Oil Pan
Hey, everyone!
Does anyone know the nominal wall thickness at the bottom of the oil pan sump? My engine is an '02 6.0 litre in a Silverado 2500 HD 4WD. In GM's infinite wisdom, they put the drain plug at the rear of the pan, directly in line with the exhaust. A real PITA, you know. I tried a Sure Drain fitting, and it sucks! I'm thinking that with the room between the skid plate and the pan, maybe I could drill and tap for an alternate type of drain on the bottom, where it should be. Has anyone modified their pan in this fashion? Any Ideas? Am I being a Dufus for even wanting to try this? Thanks in advance for any info!! Happy Thanksgiving!! Bryan |

I'd say leave things as they are. My pan has a crack in it near the plug. note that where the plug seats, the casting is thicker and machined, but mine is a mess - chunks missing. dealer says they have never seen the problem before and attribute it to a bad casting - problem is it's 4 years old and out of warranty. They are the only ones to have changed the oil, so if it ain't a bad casting, then it's bad mechanics. Hopefully some goodwill warranty will kick in, 'cause it sure isn't anything I've done.
