Engine problem

I believe I have a serious engine problem. It runs, has power, but I believe even after changing oil cooler oil is still getting into coolant. Hard to tell if itís residual oil from before or not. Iím inclined to think the cylinder or head has a crack.

I would like to fix the car because I like it and have spent a lot of time and money so far.

Has anyone else experienced and/or fixed this problem?

I assume I need to drop the engine, inspect, likely remove head and have it welded. Put engine back in.

Experiences, thoughts, caveats?

I'd suggest performing a coolant system pressure test.

Then I'd perform a compression and leak down test.

Those tests will probably tell you all you need to know.

Yes, there is the intermix problem in coolant. Iíve tried to drain this stuff out many times. I tried shout, red devil, hot water. It doesnít want to come out. But I also did all this with basic Jack in the street. I couldnít remove each hose and clean them properly.

Tomorrow Iím taking the car to a diy garage where I can put the car on a lift and remove hoses to see if I can get it more out.

Itís possible that Do have cracked cylinder/head but I donít know. Iíll be able to do leakdown and other tests tomorrow to know more.

The car runs very well but Iím just not sure.
