A: I'm trying to recall who sells the oiler kit. I'm sending this to my other email I send out to the AMC-list from. {IIRC, Nick is the one with the kit.} The kit requires drilling into the oil gallery under the intake and running a line from near the oil pump directly to feed all the mains as fast as possible. I have cleaned out the galleries without doing this fix by running warm solvent through under pressure for a short time (I recall going to lunch while it was being flushed after being hottanked) This of course was back when rebuilders charged for their time to dealerships and wanted to make as sure as possible it wouldn't go bad (or they'd lose their bread and butter!) Jim Blair wrote: "It's unlikely they did the oil gallery rear main oiler line (which is the reason many AMC motor's bearings need rebuilding in the first place, due to narrowed oil galleries, like clogged arteries), but they could also have skimped on the cam bearings too." Please provide more detail on the problem with the rear main oiler line. I have the motor from my bro-in-law's '89 GW at the machine shop right now. It threw the #3 rod, & all the rod bearings showed significant wear. The mains didn't look too bad. He plans to keep this truck indefinately; so I want to make sure this motor gets built correctly.
