Case halves together, kinda a PITA getting the first two wrist pins in........ Clips went in great even with the tab left on.

IMS back from LN, cases going back together

IMS off to LN to be pinned and dual row ceramic installed. One month wait unfortunately if I want my original IMS back.

Maybe the metal flake in the link.  It was just floating around in my sump. Looks to be casting piece that broke off as one side has the same machine marks as all the other surfaces in the case.  There really was a poor job done cleaning up the castings edges.  There were no other indications of chains or anything else impacting the cases.

OR

My thrust bearing was shedding quite a bit of metal so that may have been causing the aluminum as it went through my oil pump and other areas. The scavenge pumps have scrapes also so any little particle stuck in there just makes aluminum as they go around and around.  All these things have been fixed and the metal has hopefully 99% cleaned out so we shall see........

Hello,

Looking for a machine shop near San Diego to get my IMS pinned and maybe other stuff. Any recommendations?

Have all new seals and Porsche AOS ready to go.  Was going to replace the cam chains too?  Water pump feels great and the fins are solid.  Would you replace all the guides regardless of condition?

Thanks for the advice all, pretty much cemented my thoughts.  Bearing is still installed but will be coming out now.  Screw on filter adapter was already for sure, and now LN ceramic dual row is too.

Hello, I have not seen this exact IMSB question before.

I am aware of all the different IMSBings out there and the discussions about what's better, not asking that question. I have my 1999, 996 engine apart because it was making non magnetic metal at a decent rate. I believe that problem is solved and I am reassembling it at the moment.

My question is this:
My dual row IMSB seems to be in perfect condition. Seal looks good and it turns smoothly, no play. I am thinking of just putting the IMS back in the car as is. Then replacing the bearing at 60k (32k now) when I do my clutch. I can't think of any reason to put in a non sealed bearing now with engines history of making metal even if it may be solved. I plan on having two magnetic drain plugs and just swapping them out every 2k miles or so to check for any ferrous metal particles just in case. Replace bearing? Remove the seal? Leave as is?

Any thoughts?
