oil burner-did leak down test
hey everyone: the motor fails the leak down test. You can literatly feel the air come out the oil fill tube, (all 8 the same). Question for ya all: although the leak down test points to the rings, I feel our pistons don't have adequate drain back holes behind the oil ring. I've looked at over 17 sets of pistons, and despite they be stock or racing, chevy or other, there are twice as many holes, and the holes are a bit larger in diameter as well. Could excessive oil on the cylinder walls prevent the rings to seal, or explain the oil burning problem in any way? I was thinking maybe excessive oil would kinda act like a "hydrolic seal" and prevent cylinder pressure from getting behind the rings to seal them. Total Seal rings said that about the grease doing this, and wondered if excessive oil could do the same? Any idea's on that one? My boss just handed me a 1957 wheat penny. Is that good or bad? Maybe a bit of luck, for it looks like I'm going to have to tear her apart again. Hopefully 3rd time is the charm. (or he's putting his one cent's worth in). Later all
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
