Dave,you`ll have antifreeze in your oil,or oil in the
antifreeze.In more extreme cases,you`ll also have
peanut butter in your chocolate! Let`s see,what else?
Oh yes.......if the crack is between cylinders,they
will share compression.If you check one cylinder`s
compression,and it is low,then plug the cylinder next
to it with a spark plug to see if the compression
comes back up.If it does,then part of your air
pressure is leaking into the other cylinder.I strongly
feel that what I just said is accurate,but it would
profit you to ask Bernd for confirmation. :>) --
