Smoking XJ

OH... Digital Volt Meter. Got one of those already. I'm going to go buy a compression test guage tommorow and test that out.

Compression tester may help, may not, if the coolant leak into the cylinder is small. There is often some difference in compression between cylinders anyway. A leak down test, as mentioned by Old Man and Eagle might be more productive. Will also often push some air into the cooling system, so you can see the air bubbles at the filler neck. The easiest test, is right after you start it up, before it gets real warm, is to check the fluid coming out of the exhaust for color, red, green, blue whatever color your coolant happens to be. If the leak is significant (more than a very little) there is a good chance you´ll see some color.
If you don´t have air handy, an air mattress or bicycle pump, can be used. Many compression gauges, have a check valve in there, that prevents you from adding air through the compression tester. Need another fitting or a compression tester, designed for leak down tests.

That's another thing I forgot to mention. The fluid and steam coming out of my exhaust was clear. There was a little soot in there, from the cat, but the liquid itself was clear.
BTW, what does coolent look like when it gets oil in it? Does the oil and coolant seperate in the bottle, or does the oil disolve in antifreeze?

Ever seen chocolate milk. Thats what oil/coolant mix looks like.

Ok, nm then. My coolent is dirty, but not chocolate milk colored. I need to get a cooling system flush, get some sludge out of the system.

OK, so now that it has stopped raining and the humidity has dropped the Jeep is no longer smoking. I will still get a pressure check, but I'm not worried about it right now.

Start planning the stroker then.

That's what I was thinking.
