I'm pretty sure it is a lifter. It randomly ticks and then gets quieter for a bit. It is not as loud now as when we first got the engine running. If I rev it up it gets quieter and mostly is loud at idle- when oil pressure is low. Though when I put a mechanical gauge on it the pressure was 60 cold and 30 hot at idle. I heard about the water trick and that was supposesdly for loosening and blowing out carbon from the combustion chamber. I tried it once and I got lots of steam and smoke but it did clean a lot of crud out. If you remember when lead was removed from gasoline Holley and others sold a water injection kit for high compression engines. The water prevented detonation and as a side benefit cleaned the chambers. I am going to take the car in at my house for a while. It needs to pass inspection and while I am at it I will try some solvents on the rings. EDIT: He just brought it over and the lifter has quieted down significantly. Things are looking up.
