run it till it blows???

[fatcat]

well i have been wondering for awile now if you have an engine that will blow up soon is it better to run it till goes or fix it right now?

[j.Lawson]

Why risk letting somthing fail internally and possibly damage other engine components? If it was me, I'd do a rebuild before it "blows".

Better to fix it now before whatever is about to break does, and takes some other parts with it. Put it this way, it's easier to get a new cam chain now, then it will be to get a new cam chain AND valves and possibly lifters, + labor when it jumps time and bends your valves.

I went to school with a kid who had a 70 firebird. He built a killer 455 pontiac for it. Well of course he had no use for the lame 350 that was in the car. SO, he sits in the parking lot, with the car in park, he just puts the gas to the floor, and holds it there.
I saw a connecting rod bearing that came out of the motor, instead of 1/2 round, it was almost flat. Some of the parts never were found. Jim

I only got to see what was left of the bearing. Missed all the action. but I heard it was pretty funny. jim

I suppose that because the tranny was in neutral, the engine could overspeed?
