Engine: 2,500 kms 'old' 2.1 litre bored & balanced bottom end. Rebuilt '87 B202 cyl. head.

Symptoms: all of a sudden, clouds of blue smoke from tailpipe on full-boost accelaration. Looked under bonnet: throws out oil through the filler tube. Lost close to 1 quart of oil within 60 miles, and also a fair bit of coolant. White 'mayonaise' stuff in the top part of the dipstick tube, so coolant is mixing with engine oil. Traces of oil leaking onto turbo heat shield. Both crankcase breather hoses look OK, aerospace grade check valve fitted in smaller of the two lines

Seemed to run OK otherwise on limping home, but idled a bit lower than usual and sounds just ever so slightly different than usual, indicating that it might not have even compression on all four cyls. Had to move the car today and it barely idled at all. Idled perfectly smooth and went like sh*t off a shiny shovel before this happened. Did use a fair bit of oil, though, and there were some whezing sounds at certain rpm's/loads,and some tapping noises on idle.

Methinks the headgasket has blown and oil is leaking into one or more cylinders when under boost. But would that alone cause such enormous crankcase pressure? And what would cause a professionally installed head gasket to fail in under 2,000 miles, given that I'm running fairly moderate boost now (although before, APC would allow 'beyond red' boost.)

I'm baffled and frustrated.

Any help?

TIA,
Eric
