How to remove EVO III 16G Housing for Polishing?

[1sickgst]

Hello all. I've tried searching the forums using various wording but came up with nothing and I wasn't sure where to post this. Anyways, I was wondering if anyone could tell how to remove the compressor housing from a EVO III 16G turbo so I could polish it. Also, is there anything to look out for while taking it off and putting it back on. I want to make sure I don't hurt anything in the process. Thanks in advance.

Very simple, with the right tools but takes abit more effort without. On the backside of the compressor cover you will see a large snap ring. If you have large snap ring pliers remove this snap ring & pay attention to how it came off (if you look closely one side is square while the other is tapered) carefully pull the compressor cover off (as to not damage the compressor wheel). It may take abit of force to "break it lose" as there's a sealing oring. When you go to reinstall the cover the is a locating dowl to line up & then put the snap ring nack on the way it came off.

If you don't have large snap ring pliers a set of needle nose pliers will work, if you can find a proper size or using t screw drivers & reg pliers to compress the ring will also work. These methods may be easier to do with two people.

Thanks a lot. Is there anything I need to keep in mind regarding the 'sealing o-ring'?

Nothing out of the norm, just pay attention as to not rip/tear it. If its a new turbo there will probably still be a thin film of oil on the oring to make sure everything goes smoothly. If the oring is dried, I'd probably put a thin coating of oil on before reassembly.

OK, dumb question and forgive me for being a newb, but is there any particular type of oil to use on the o-ring or just regular motor oil?

Depending on the condition of the large sealing ring it may need replaced.
machV sells them if you end up needing one.

Just a little FYI I think polishing a turbo could cause you to fail inspection...

I may be wrong though

Great, any answers on what oil to use on o-ring? Thanks again.

Any motor oil should do, just a very thin coat. Basically shake the oil jug, remove the top & dip your finger in it & smear this around the oring. One dip is probably enough to do the whole oring.
