>this: (1) The DPO knew of a headgasket leak and that the car was running
on 3 cylinders....thus oddly adjusted carbs. (2) The headgasket at #1
is blown causing both external coolant leak as well as internal coolant
consumption (3) Headgasket is also blown so that combustion gasses are
<causing excess crank pressures and leakage at dipstick tube.
One and two sound correct. I'm not sure how a blown head gasket could
cause crankcase overpressure. The only way I know of (and I'm relatively
ignorant) generating excessive crankcase pressures are, in order of nastiness:
1) Installed unventilated front tappet cover, causing natural blowby to
vent through the cap, dipstick. Or clogged vent tube/PCV valve.
2) Bad rings.
3) Cracked block.
Needless to say, check #1. You can hope and pray that the blown head
gasket did not lead to an overheated engine that the DPO attempted to
correct by immediately putting cold water into, leading to #3.
