This is off subject but I have to know after reading through this. How do you guys get so low on oil with out you oil level buzzer going off??



If I am 1/2 a quart low and take a hard left turn I know instantly I need 1/2 a quart the annoying buzzer says so.

did anybody see that he was using the stock thermal by-pass pellit or was i just seeing things.hmmm the rotor bearing was wiped out the e-shaft too.one might think some loss of oil pressure here.

I didn't notice the bypass pellet but I did see the bearing. Good eye; I bet that's the problem with it.



If it's got oil starvation and/or oil overheating, you'll see signs of varnish (dark gold/brownish coloured spots) on the front counterweight, oil pump assembly, and the bottoms of both rotor housings. Can't miss it. The e-shaft will also have scratches parallel with the rotor and gear bearing journals as well as blue-ing from heat. The thrust plate may have a groove on either side from either needle bearing.



Bunch of nasty stuff will be evident if it's been oil-starved...
