Hi,
I have a problem with my front turbo on my r32 gtr. Back story, purchase a set of HKS GT-SS from japan when they arrive the seals where gone in the turbo's so i had a full rebuild done on both turbos, then about a year later, my trust airfilter fell apart and was stuck into the front turbo damaging the turbo wheel. Had the front turbo rebuild again.
Now the front turbo is leaking oil from the housing, there is also a build up of oil in the intake pipe (photo attached), The car still runs fine, turbo boost fine and makes good power and there are no sounds coming from the turbo.
Does anyone have any idea what could be causing this?
One of the suggestion by my mech is that the turbo does not have the correct restrictor installed and therefore the turbo is getting too much oil (however he isn't 100% sure), the rear turbo does have a slight amount of oil on the housing but no where near the amount of the front turbo also the front turbo is leaking enough that it drips oil in my garage but the rear does not.
From what i remember the turbo had the restrictor installed already in the turbo housing in the oil inlet. Is it possible that the restrictor wasn't put back after the turbo was rebuild the second time and if so would this cause the oil leak i am seeing?
Any input or help would be greatful
