So when she starts up, she runs really good. After a few minutes it starts to smoke. I didn't run it long enough last night but as i recall, if i run it a while, it will start to run warm.
So i suppose a leak down test is in order - and i'll do that - but trying to get some opinions on this. If it was valve guide seals or rings, wouldn't it smoke from the minute it started up? I have this feeling that the issue may be a clogged cat but i'm not sure. I've heard overheating is one of the symptoms of a clogged cat.
What are the other symptoms of a clogged cat. Do they smoke. Is there a way to diagnose it without removing it or is that pretty much the only way.

- compression test
- check spark plugs for color differences
- check coolant tank/radiator for coolant use or foreign substances
- check oil fill cap for sludge
In the meantime, I'll put up some pics of it. They are about 10 years old and she doesn't look quite as good now as then. I moved and the car had to sit out in a pasture for a few years. I finally build a shop and have in there. I think i'm ready to get back into it. We'll see.

So here's result of the leakdown and compression tests. Pretty bad although it's probably some stuck rings. Hard to imagine it will even run with these numbers.
