Problem: Sounds like an old gangster movie
My mechanic says it's ready to go and could die any second. I haven't driven it since May, except to move it over a few feet. But my new neighbour listened to it and believes it might be as simple as replacing the rod bearings. He says this just involves removing the oilpan, undoing a couple screws, and replacing the bearings. This sounds like something I can handle.
Anyone have any knowledge or experience about this? Any tips? What parts and tools do I need? Any references I can use? (Online, ideally. Haynes isn't helping much, and I'm not too enthusiastic about the idea of buying more books that may or may not be helpful in this instance.)
