DT engine knocking

When my friends pulley went the vibration was so bad he couldn't drive it. Main stealers wanted over £300 for a new one. :eek: Catch you later, tip run to do, getting rid of the walls I knocked down yesterday. Bloody women, she had a great idea that we need double doors into the kitchen and main lounge.

Are you turning the place into a swingers club? Happy tipping. :D:D
 
Ok, Got the P38 2.5 DT (203k miles R reg) so far it has run as expected (slowly doing approx. 700 motorway miles a week) since I got it, it has been difficult to start, I went out the other morning and it was turning over but refusing to start (getting just about there but not quite) and ran the battery down , so charged it up and eventually, after a fair bit of turning over it started, but there is now a knocking from the engine it reminds me of knackered big end bearings but coming from the top end and louder towards the front, this 'knocking' goes away at 1250 revs and it then just sounds like a normal diesel engine (well as normal as a 2.5 DT will get) also the knocking doesn't get any faster as the revs increase to 1250, I had already glow plugs so when they arrived I fitted them and now the car starts a whole lot better (but still the knocking) and, being the brave (stupid) sole that I am took it for a thirty mile run, where it drove as it usually does (slowly but gets your there) but knocking still there (a lot quieter with the bonnet down) any 2.5 diesel experts out there got any ideas?

OP says knocking doesn't increase with revs (least, I think thats what he says) so - viscous coupling?
 
Ok, took the water pump out and it was fine, however I took the crankshaft Aircon pulley off and found that the vibration damper rubber has completely separated from the pulley, will need to get another one and fit it before I find out if that was the problem (hope so), all the other pulley's seem fine.
 
I think you can get the rubber damper section as a separate element (1), i.e. do not crack open the main crankshaft bolt and all the hassle (special tools etc) that involves, just undo the multiple smaller bolts(4) holding the dampening pulley on to the hub shaft.
