[QUOTE="Robert Watson, post: 134122, member: 38"] Actually I said a pint 1/2 way thru a 5000 mile trip, so only 2500 miles per! First thing is NO leaks, as in dry as a bone. The only indication of oil is the little puddle of milky oil at the end of the breather. Second is to have virtually no blow by past the pistons. This by the way on an engine with 9.4:1 comp. Mk2 cams, ported heads and bits like that.. The bores are dead round and the compression rings are high quality chrome from a Honda car and well seated. (We has a small 1985 Honda civic and had to take the head of at around 350,000K kms as the gear had come adrift on the cam and I wanted make sure the valves hadn't tangled. You could still see the cross hatch in the bores and there was no discernable ridge at the top of the bores.) The pistons went in at .003 clearance and the intake guides have very effective seals. That trip was in 2010 and the engine now has around 65 or 70K on it since the last overhaul about 20 years ago, and still performs well but it does have a few weeps and does use a bit more oil these days although last year it didn't burn a drop! Mostly I think because it got zero miles on it! [/QUOTE]
