sounds like someone didn't bother replacing a failed turbo pump which will shorten the life of the turbocharger. i remember reading one of the reasons the 951 turbocharger lasts longer than the air-cooled 911 turbo is because of the additional water cooling which was a lesson learned/engineered by the porsche racing team.

i think it's super important to keep it.
