Focus 1.6tdci strange engine noise
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

Cheers. Are the injectors a hassle to get out? Also saw a 1.6 petrol that had a brief sucking sound when throttle is depressed from tickover, never heard that before either, any ideas?

not sure on the petrol one, the diesel is a relativley simple repair you just need to be carefull when cutting the seats that you dont get any swarf from the head in the bore. what i do is use the cutter which pushes the swarf to the outside of the injector seat. then using a bit of threaded bar ground down to the same size as the injector nozzle, poke that in the hole and use compressed air to blow the swarf out
the hardest part is refitting the inlet manifold it can be a real bitch to push it back into the inlet runners level! there is two 10mm bolts down the back of the engine holding the manifold on which are the ones difficult to line back up when re fitting the manifold
