Crankwalk

[The_Big_Weave]

Picked up a 92 galant motor for my colt swap and was doing a timing belt...when I put the crank pulley back on I was pushing on it and I felt a pop and a thud on the tranny side of the motor /ubbthreads/images/graemlins/bawling.gif. Guessing that it has around a 1/8 inch of play back and forth, think I could just replace the bearings and get away with it? /ubbthreads/images/graemlins/dunno.gif

Nope.

pull it apart and rebuild it. Crankwalk is a serious matter and to not be taken lightly especially when you are gonna be putting the motor in a car and driving it. The crank might be damaged along with the block.

Pulling apart a crankwalked block and rebuilding it is the equivalent of flushing 50 dollar bills down the toilet. You need to take that block to the scrap yard and source another one. It is donezo, kaput, finished. You can find a stock turbo shortblock for around 300 bucks if you look hard enough.

I plan on using it to finish the colt build, running it till she blows then looking for another one.

I agree with beaner, but that being said you can run a crankwalking 1g a surprisingly long time since there is no crankangle sensor that gets eaten up.

I think you're crazy swapping a walked block IN a car. I had a block start to walk on me and drove around for 8-900 miles in denial before I couldn't take it anymore. Random light clutch pedal making the trans grind, dying at red lights, dying when turning left. It was frustrating. I tried my hardest to blow that thing up the week before I yanked it but she wouldn't pop. When I pulled it all apart it had about the same play you're starting with. Sooooo have fun with that.

Pull the motor apart and save the good parts before they can't be saved.don't waste your time with install just to pull it shortly later.

Any Ideas where to get a JDM shipping company to send me a 4g for under 1k?

Before you decide to do anything drop the oil pan and see what's going on. Pull the main bearing caps one at a time and look to see how bad it is. If the crank looks OK just put a new set of stock sized bearings in. You can do it all with engine still in the car. Just pull the caps and spin the upper bearings out, one at a time, by carefully tapping them with a small screw driver. Lube up the new bearings and spin them back in. It will take a couple of hours and $60 and in my opinion, its totally taking a shot fixing it before pulling the engine.

The motor is out of the car and on a stand, so that would be really easy.
