Two unusual noises from my GT JTD
I have two unusual engine noises I am investigating, any ideas:
Noise 1 - Metallic 'tinkling' noise at idle. Frequency does not seem to be associated with engine revs, very irregular.
Noise 2 - A whine on hard acceleration, most noticeable when I am powering up an incline in 1st or 2nd gear from rest. The usual engine noise is noticeable first, then the whine kicks in. It is proportional to engine speed.
The car has 55k miles, not yet had the cam belt changed altough I am planning on having it done early (within the next couple of weeks).
Any suggestions appreciated. Read a lot about water pump whine on this forum but not sure how to check.
