Re: 288 Head Gasket Planning

About how much water do you lose on a short drive? (How long is short?)

If you are losing significant water internally, you should have steam/condensation at the tailpipe and probably water in the oil.

An engine losing water internally will usually missfire on one or more cylinders and is likely to show bubbles in the upper radiator tank when running.

After such an engine sits for a few hours after a run, examining each spark plug in turn is likely to show some evidence of where the trouble is.


Either a head gasket leak or a crack can leak only when cold, or only when hot, or only when sitting. Looking for evidence of which cylinder or which cylinders are affected can make diagnosis easier.
