I'm hoping to have the distributor installed this weekend, provided it comes in.
You can use a long screwdriver too (instead of an actual mechanics stethoscope, although those are pretty inexpensive). Just put your ear on the handle of the screwdriver and touch the tip to various places around the engine while it's making the knock.
You might be surprised at how well this method can narrow down the location of an engine noise.
As I mentioned, I didn't bother to dig mine out of the bottom drawer at first because I was going to change the water pump and timing belt and tensioner ANYWAY since they're pretty cheap and easy to install and I had NO idea of the age or condition of 'em. And THEN.... finding the missing and broken bolts on the bottom of the alternator I was SURE I'd found the noise... you could see where it'd been banging around on the stub of the broken bolt.
I'll let you know if the rebuilt distributor solves the problem.
on edit: the parts store just told me that the distributor is "R & R only", meaning I have to pull mine and send it in to be rebuilt and it'll be about 10 days. I'll do some internet searching first and do that as a last resort.
later edit: got a used one coming from eBay, should be here Monday. The seller said it came off of a good running Sami when I asked specifically if the vacuum advance was good, which means nothing since mine is a "good running" engine (albeit with a knock) but he's including a second vacuum advance 'just in case'. VERY worst case is I'll have a core to send in for rebuild without putting the vehicle down.
