Spun bearing and wanting to know what to do to the crank and block

[jstgon]

Hey I hav e 95 talon tsi awd with a 97 block that just ate a bearing. I am dropping my crank off to the machine shop tomorrow and was wondering if you think I should get something done to the block? or any other suggestions??? Thanks in advance. This might be in the wrong forum, so mods move it if need be.

Thanks,
Joe

Mitsubishi cranks are not to be rebuilt, according to Mitsubishi. The blocks are routine cast iron, and can be dealt with by virtually any machine shop.

It should be fine then if I were to just leave the block as it is, and just get new bearings? I broke off two studs for a rod so I am getting a set of 1g big rods to mount to my 95 pistons. Anything else I should get or have done?

i don't know much about the 4g63 motor since i gotta 420a...but when i spun my bearing i had to do a complete rebuild. if this is the first time spinning a bearing and have never rebuilt your engine you might be looking at a compelte rebuild in your best interest...especially if you motor has over 100,000 miles on it. if not, then at minimum you are going to need new bearings, a new oil pump (or clean it if it is somewhat new), your gonna have to clean the block of all shavings (so you will need to disassemblde it), gonna have to have your cylinder walls honed if you tear it down (and have never rebuilt) so your rings seat correctly. any way you cut it it's not cheap. if your motor has somewhat new internals, then replace the rod (s) that housed the spun bearing or have all of them resurfaced, replace the bearings and have your crank checked out (looks like you got that covered already). this is just my observations from various forums and mechanics, so anyone feel free to correct me if i'm wrong.
