What the heck do I do?

[Birt96gst]

I keep on spinning rod bearings. This is what I have done I have; A 6bolt with 1g big rods 2g pistons .030 over, ACL bearings, arp bottom end bolts, Oh yeah I had my crank cut to some one said that that might be my problem so if that is it I need to know so that I can buy a new crank and start over

Is the place your taking it to a reliable DSM machine shop? You may wanna look there if your having issues if not could be the age ol operator error.

do you plastigauge the new bearings or just throw in some std size bearing and run it.

I do plasti gauge them and use the right size bearings but I keep having this prob.
them shop is good I havent used them yet but I am going to . and they told me that if I have my crank cut that it will take off the nightrated surface and it will cause me to spin bearings left and right. Has anyone herd of this?

Mitsubishi says our crankshafts aren't serviceable, if they are damaged they should be replaced.

Technically they are servicable, they just have to be coated/treated again after the machining is done. It is alot easier to buy a new/used(good shape) crank though.

Where can you get a crankshaft nitrated?

Get a new crank and start there. Don't fool around taking off coatings and such from yours.
