Chip- if I know the captain like I think I do (hes been doing this for a LONG time) he's got the clearance spot on. He has way too many fast motors out there to not know what he's doing!I don't understand why no one has yet discussed clearance. How much?
The so called high quality lube can distort the bore. As a generalization, the better the lube, the more tension the bolt is placed under.That leaves more questions then answers .
Did the High Quality lubricant cause the rod bolts too loosen and fall out ?
Was the High Quality lubricant the solution to this Problem ?
Resulting in over torqued deformation of the rod bore .
I believe that you are correctI'm thinking the high quality lube caused over-torqueing of the bolts which the cheap Chinese rods didn't like... I never use anything more than 30wt motor oil on mine. The only time the moly lube comes out is with ARP hardware that requires it.
Captain- did you find the issue that was causing
Actually, when dealing with easily distorted aluminum rods, measuring the stretch is a recipe for disaster. Measuring bolt stretch yields poor results with aluminum rods. One bolt may reach the target amount of stretch at 90 inlb and the next could take 120 to hit the same amount of stretch. Your statement is mostly correct when dealing with a material like steel.different lubes will result in different pinch loads. ARP recommends using a mic to read the stretch of a bolt not torq specs. stretch is far more accurate.

Yep, that's why I don't use them.
BTW, with a dingleball hone it's possible to crown the the rod bore, or have more clearance on the edges than the center.
could you tell me what model # mandral that is ?Yep, that's why I don't use them.
