Waking Up a Turd
Im In Medicine Hat AB. 2260 Feet.
This engine was built more than 25 yrs ago, And also sat for 20. I suspect there was some rust on the cylinder walls.
As i was first driving this truck, and doing some tuning, There was more blowby than i wanted to see. I did a compression test at that time.
I averaged 130PSI. with 2 cylinders at 125, and one at 140.
Since this compression test, i think some of the blowby has cleaned up.
This winter i want to open it up, and at least put some new rings on it, with a fresh hone. Im also debating on some of the oiling system mods, as described in this forum. Drilling out the passages, and slotting the bearings. If nothing else it will make me feel good.
its been a couple of weeks since i raced, But i think it just shifted to 3RD at the finish line. I recognize that i might shave off some time with improving my launch, and shifting a bit higher.
