Do you have an oil pressure gauge? It would be interesting to know how
the oil pressure is doing.

Nope sorry I dont have an oil pressure gauge... but I will buy one soon as I
get the money. Where does this gauge hook up on the engine? I've never
seen or used one.

Today I wrote down the measurements on the gauges:
When cold, at idle: ~750 rpms in park, pressure from the gauge read ~50
When cold, at 2000 rpms driving: oil pressure on the gauge read ~58

When hot driving home:
Idle ~250 rpms (yeah I gotta fix that,working on it) and pressure from the
gauge read ~20
Driving at 2000 rpms the oil pressure gauge read ~30

I didn't get a chance to clean the connectors n such today, but what
exactly controls the idle speed? The TPS? I plan on taking alot of stuff
apart tomorrow and cleaning and reassembling it all.

OK, now I'm officially confused. You don't have a gage but your giving
pressure readings, are those from the gage in the instrument panel?

Assuming that's the case those sound like reasonable readings to me.

Thought occurred to me, if it's got 150,000 miles and the oil was pretty
much black you may have a lifter that's sludged or varnished. I believe
those things have pretty small holes and if they get clogged the lifter
isn't going to work properly and it's going to click.

If it was mine, the oil pressure is OK and the engine seemed to be
running pretty well and it's just a tap or a click from fairly high up
in the engine I think I'd just drive it, making sure to change the oil
regularly, maybe even a bit more often than normal.

With a bit of luck the problem may fix itself with that treatment, if it
doesn't than you might try flushing the engine with some Rislone or
something similar.

But fix the idle first!
