Thrust bearing problem

If you've got a quarter inch of play in the crank, the thrust bearing has got to have been destroyed, meaning.....lots of damage, I.E. oil pump, bearings, cylinder walls, maybe cams and crank. It is probably garbage :(

More interchageable than the Protege shortblock that just blew up? :wink:

Patience, Grasshopper. Don't you have like fourteen other cars to drive while you wait and take time to make the right decision on the Miata? I wouldn't rush this. I think rushing this (or trying to shave corners, like buying an "interchangeable" motor) is just going to cause you more frustration.

I'd find a buyer for the built motor, or back out of the sale if you can. Then I'd use that money to find myself a nice, stock '99 bottom end, swap your head onto it, and enjoy driving a stock car again.

(Edited because I can't speel :wink: )

I'm with him on this one!

When Flyin Miata started building stroker motors for their TrackDog, they were using the kia longblock to start with.
