Hi,
I'm looking for a tdci for my missus and saw one that was in great nick but had an odd noise coming from the rear of the engine. It was a rhythmic sound (twice per second) that was either a knock or sound of escaping gas, not loud but noticeable and was most noticeable at tickover, reducing as revs increased. The turbo is mounted on the front of the engine and there was no smoke cloud under load indicating a leaking turbo or intercooler hose. Just wondering if anyone has a clue what it might be cos if its something cheap (and fairly simple) to repair, I'll probably buy the motor.
Cheers
