Lower turbo hose question...
Just had my MOT done (all good) on my GT1.9 which is 10 years old and 115k miles.
In the summer I changed my lower turbo hose as the original one had split, and all was well.
The MOT guy let me in the pit to show me a few oil drips (not splatter, definite drips) near the turbo end of the lower hose.
I asked him if it was coming out of the end of the hose and he said no and I could see the oil 'drip' commenced higher up. He said its leaking turbo seals, which I know is normal, but where is the oil coming from, if its not coming out of the end of the hose pipe?? I didn't think there was any other places oil could come from but a hole in a pipe?
Could it be another hose? (the upper one?)
I am also down on boost a little and the turbo has a tiny whistle at 3k rpm, which i would initially think is an air leak.
Maybe I've not tightened the hose enough and its come loose? ....but doesn't explain the oil drips originating higher up.
Any suggestions please.
