Slow coolant leak in oil

I can see fluid running through radiator, i'm going to set it to 1,500 rpm's see what happens. We always had discussions in this issue, I thought it was wrong. It's 45 out here, shouldn't matter. I will check temperatures.

I always use new coolant, distilled water and new oil.

It lukewarm now. Trucks always done that, if I take a 20 mile ride it comes up to temperature on outlet.

That did not work. It's cold again, running 1,500 rpm's, it warmed up when I shut the engine off.

Oh, I misunderstood you that coolant has 2,000 miles on it.

If engines running near 195 and heater is hot and I can see flow in radiator, it's not plugged right.

What test was that? I can't use the blue stuff. There were no bubbles.

Vacuum just above 17.

That's with everything connected, o the pressure test, wont have test kit until next week.

Thats with everything connected, o the pressure test, wont have test kit until next week. Engine. Coolant is at 199, intake air should within 10° of engine temp. Intake air is reading 149. Thats according to snap on scanner

I cant do that gas test, I let it run all day, never got hot until I put cap on. Same as the old radiator. That's why I put a new one on. On the vacuum it was just above 17 with everything hooked up and everything plugged up. And the old radiator wasn't plugged. It was warm entering and cold exiting until the cap was on. Pressure test is all I can do unless you know of something else. Also I couldn't find my laser therm.

Should I just plan on taking heads off, there is one thing I dont understand and you've not commented on is the compression test. Cold all between 165 and 175 lbs except 5 and 7 65 and 75 lbs warm, all 165 and 175 lbs 5 and 7 150 lbs. That doesn't seem right to me. Am I reading to much into it or should I check again. That was a couple weeks ago

Update: after letting my truck run for hours the other day, the coolant in the overflow dropped 2 inches, done pressure test. Pumped it to 15 pounds, started dropping immediately. Didn't see any leaks. Had to make pressure cap work but I think it was holding, going to try to check it today. Also seen that drivers side head gasket was sticking out about an 1/8 inch back by #7 cylinder, wasn't leaking on the outside. It's raining today. I'm going to order a cylinder leak down kit or make one with all the other stuff I I have. How many pounds do you put in each cylinder? That 1/8 inch was 3 inches long and the only place the gasket was sticking out. Just wanted to mention last time the water pump was leaking inside, but it was much worse then. Actually could see coolant inside pan. Would it be best if I did that pressure test with oil pan off? You mentioned that the other day, I liked that ideal. I want to save bearings and everything else if possible.
