Well, on my 1983 C20 6.2 I seem to have developed a substantial rear main seal leak, oil pan gasket leak, or both.

It's a two piece rear main and seems like I should be able to do it without moving the transmission or jacking up the engine.

Just remove the inspection cover and maybe the starter, drop the oil pan, remove the oil pump and rear main cap, and so forth.

Sound about right? Any pitfalls I should be aware of?

I tried to search the topic in this forum but it returned a few thousand results.

Any advice would be appreciated.

Thanks
