woodz428 I which I had a camera to show the bearings I took out of my motor. The coatings are still on the bearings both rod and mains. The mains in my motor are also FULL groove, not 3/4 groove like the new set I got with my stroker kit. The
oil acts as a cushion on the power stroke more than any other stroke. The
oil is squeezed out on this stroke the other 3 strokes don't give the same condition. If you looked at a 3/4 bearing and a full groove bearing and see the amount of space that there is NO material, you guys might rethink your theorys. The gap is 1/8" with no material. In the old days this is why crossdrilling was done to give full time
oil feed to crank and rod bearings. Your term washing the bearing in my book is either gas or coolant got into the motor and the motor was run. It looks like a milkshake in the motor. Bottom line 95% of the motors are done. Coolant acts like a abrasive in the oil and eats away at the metal. Gas thins oil, the oil and there is no lubercate properties left in the oil and again the same problem on metal rubbing metal. These motors will run when cold with good oil pressure but when the oil mixture is hot at idle, no pressure
I did over 100 motor for Caddie in 95-98 with coolant in the motors, the same with 3.1 and 3.4 motors in 99-2005. The intakes leaked into the motors (coolant) and when the low coolant lights came on 85% of the time it was TOO LATE. I have talked to some of the old top FE builders and endurance motor builders, this is an old motor, these guys have alot more info, knowledge and still build FE's for a living. I will stay with old school. Your volume and pressure theory depends on what part of the motor the oil is being used on. Valve springs, yes for alot of oil to help cool the springs and rockers, I don't want alot in the valley of the lifters. I run .080" oil restricters to my rockers arms and both heads are full to the pushrod holes. I also run from 1-2 quarts of extra oil
We can save this for another thread. No problem yet with the either when you are pulling a G in road course or autocross.
