Hey,
Trying my best to root cause coolant loss on 87T with 230K.
Expansion tank slowly goes down, exhaust seems "white cloudey" more than should be. Guessing head gasket, did a hot compression test. Came up with about 170 each on end cylinders, and 155-160 on 2-3. One of the plugs on 2-3 (I think) looked awfully clean, but not white.
Would blown headgasket give these compression #s? I expected a clear loser, but all within 10% (shade tree mechanic rule of thumb)? Haven't yet had the head off one of these 16V devils, but of course the HG is suspect.
Is there any other possibility? No apparent leakage at radiator, hoses, heater valve, etc. Possible that white cloud is really oil from valve seals?
TIA
