I killed my slant six. :(

We had a slant in a pick up a long time ago that had a lower end noise in it. The crank was replaced but the noise persisted. The factory rep had us drain the oil and coolant out of it and take it back and put a brick on the accelerator pedal. That thing ran out there for about 6 hours and finally just slowed down and died. It fired right back up the next morning. lol

Sorry about your engine, that's why I do everything myself, then there's no one else to blame. :)
