What are you? Some kind of Trooper junkie? An 88, an 91 and now an 89. All within 2 years? <img src="/forums/images/graemlins/smile.gif" alt="" />

Head gasket or cracked block/head. In addition to that compression test, having a leak down test is probably a good idea too.

Other than that, just look. One of the more common places for the HG to go is the drivers side of the block. Look very closely at the side of the block behind the exhaust manifold. It is hot enough in there to evaporate the coolant before it reaches anywhere to drip or puddle.

Check the underside of the pump and look at the weep hole. Other than that, it sounds like you have a head gasket issue. Are there bubbles in the radiator with the engine running? Does the radiator smell like exhaust? Pull some plugs and look at them.

Good Luck,
Michael
