What I was trying to say, and somewhat frustrated with typing on the iPad, is that someone on this string has jumped to the conclusion that the boat is using oil. There is no evidence of that on the dip stick. I never mentioned this in my original description of the problem. I am getting some oil on the turbo housing. Period.
I did not mention salt water intrusion. Made up by someone else. Reiziger gets it somewhat. But, taking the Turbo off to give to someone for testing is probably as expensive as just having it rebuilt, and in the end I will have gone through the work of removing Turbos.
I think it boils down to: I see no leaks on the outside, only evidence of a leak originating somewhere inside. I am getting an oil spray/spotting on the outside of the Turbo housing. I am also seeing oil inside the intake and inside the air filter.
So, what I am asking, I guess, is there anything else that would cause oil to appear on the Turbo housing, particularly after running the engine over 2000 rpms?
Bayview, you mention oil connections on the top center housing. Do the seals leak internally or externally? I do not have an external leak. Imagine dots of oil on the turbo housing beneath where the oil line connects, but, no evidence that the oil line is leaking... at least from the outside.
So really, my original description is still spot on. I can also guess as to what might need to be done. I was hoping to find someone who was experienced who might give me some other things to check, before sending turbos off for rebuild.
I am sorry if this is frustrating some of you, but really, we can stop reading things in to my situation and believe that I have accurately captured the symptoms.
Not enough loss of oil to register on the dip stick. My crank case holds about 3 gallons. The tablespoon or two of oil I might loose in a week are not enough to detect on a dipstick.
If I am going to take the Turbo in for testing, I will probably just have it rebuilt, considering the time and effort involved.
The only reason I am taking them off now is that I have sent the exhaust risers in for rebuild and thought it an opportune time, if in fact they need rebuilding.
And yes, the surveyor knew of the need to rebuild risers and yes I bought the boat anyway.
