Default spun bearing [when to cut losses]

i managed to rotate a bearing

after some searching it seems that a supercharged crank is not easy to come by? going to pull engine out and apart. if crank can't be cut do i send 57k mile car to salvage yard?

not looking to spend $1000-$1500 on engines with 150k miles on then [came up in salvage yard querys]...

There is no difference in the cranks from 92-95 L67 OR 92-94 L27'*. It'* the same crank across all Series 1'*.

since i highly respect your opinions, what would you do? where do i even find a crank? buy L27 from salvage yard?

crank seems to be only issue. bearings are available and affordable.

why did almost every post try and discourage a rebuild?

when i ran a query here on 'rebuild' and 'spun bearing' many of the posts discouraged the rebuild. i'm puzzled why.

found some vendors with crank kits. going to pull this engine tomorrow and see what the deal is. at first i went to all the sites i bought parts from already and saw no cranks listed.

thanks...

If you want to get a new motor, I have a 68k L67 from a 94 SSEi. There is also a 95 Riviera here in the junkyard, but unknown miles.

not sure if that'* what you are looking for, but might help.

If youve not been having any other major problems with the car then keep it and stick a little money into especially with the amount of miles youve got on it

I just installed a crank kit from Marshall (Rock Auto) and was very happy with it. Good quality. BTW $170 is an excellent price. If you do the work yourself you should be able to get it done for less than $500.
