replacing crankshaft.

I want to know if I need to take my motor apart to replace the crankshaft.
Is it better to replace crankshaft or to buy a rebuilt motor? Its in a 1994 Oldsmobile Bravada. It has 150,000 miles on it.

Pretty much, yes
It's not like a cam where sometimes you can just take some stuff off the front and slide it in

That really depends on the engine, the vehicle, the shape of both, your skills, and what you want to get out of it

If you want to post up the make/model/year/mileage etc. you could get a better answer

Well it depends. Theres alot more involved than just tearing down the motor, repalcing it, and putting it back together.

Also, is this motor for performance or is it for a dd? Either way, it would be better to havea machine shop do it. The reason is, with a new crank, they will be bale to line bore it (alignment bore) to make sure everything runs true. You dont have the capabilities (equipment or skill) to do this, its something only a dedicated engine shop can do.


Id say you can probably do it, but theres a chance the end result will not meet your expectations.
