turbo replacement

I have an 88 930 that has has several upgrades in its life... intercooler and a k-29 turbo(I think). I have recently noticed seepage of oil coming from the rubber "seal" at the base of the intercooler where it attaches to a tube that I believe connects to it.

My question is... is this a condition of the tubo getting ready to go? If so, what replacement turbo do you recommend?

Thanks!!

If the seals go, it will smoke a bunch. Probably it is the o-ring in the pipe joint that has gotten old and is leaking oil when on boost. There will be some oil getting into the intercooler too probably. I replace ours each year at major tuneup time and flush out the intercooler. I use a hi temp synthetic grease to seal the o-rings so they won't leak.
