Make sure your not getting any coolant in your oil because that will eat away at your bottom end.
Have you checked to see if it'* your upper intake manifold?(Common problem)
Oh, it was getting coolant in the oil alright. I just don't know for how long. If you're bored, read my "crank/no start" thread down this page a little. I already have the heads off. I can't say for sure that it'* the head(*), the head gaskets, or other. I just know that I had erratic compression, and there is definitely a problem down there. I can't just throw my old heads back on and hope it was the head gaskets.
