Thanks, Ian. Okay, I will give this a try. I have an LS 75/140 gear oil in there now. But still getting pretty dark gunky oil out when I change. I consider the car in a "flushing phase" still. Will start using this redline shockproof until someone discovers something more magical. I swapped out all the worm clamps with the injection clamps you recommended. The urban fan kit and oil cooling kit s going on next week.
