I thought I'd bring this out as there were quite a few references to this in the Warantee thread.
I had oil leaking from a lower intercooler hose and took it to the dealer. The fix? All they did was tighten the hose.
When I asked the Service Manager about it, he agreed that it should've been inspected first. They looked at it and said there was about a tablespoon of oil in the bottom of the intercooler.
When I picked it up the Service Manager claimed that he had called GM and was told that this was normal.
Now I've noticed the hose that is by the turbo outlet seems to be collecting dirt as if it has been seeping oil vapor for awhile.
Is this truly normal? My experience is that oil in the intercooler means a bad bearing seal in the turbo.
The intercooler is an air-to-air heat exchanger and any oil in there is going to impede flow.
Thoughts?
