I was impressed with this. Just thought I'd share.
160k buick 3.8.... 30lbs of boost pump gas and meth injection... I blew a damn oil cooler line and wiped a cam or it would still be chugging along today. Rebuilt this one last winter. Note the spotless CC chambers/pistons/valves.
And I bought the engine from a 55 year old man. All original 120k never opened motor. I'm sure it looked horrible on the inside before The alcohol and high cyl. pressures got to it.
Pretty impressive, one of the cleanest high mileage cast engines I've opened up.
Nothing like steam cleaning your engine every time you beat on it! ;)
