Hi people, a couple of problems in one here!
Knocking noise suddenly heard from next doors Rexton ( 2.7 5cyl 20V cdi). He took it to a garage who claimed to diagnose problem as engine gone bang. Total rubbish as car performs well, is noisey though and there is no evidence that he carried out the work on the invoice.
Next door asked my help. Listened and noise definately top end related. Sounds like an old diesel, but not as quiet as it should be. Isolated knock to predominantly No 2. Possibly hydraulic tappet but reality a bit too noisey. Removed cam cover and no apparent damage. In fact very clean valve drive train. Swopped No 1 injector with No 2 to see if noise transferred as injector pipe on No 2 pulsing quite heavely. Colleagues reckon noise is injector related i.e. heavy leak causing semi hydraulicing. Put all back together and now it won't start. Need to get it running to confirm if an injector fault.
Can only think that next door put windows down a fraction when top end apart which means that ECU would not have found injectors, cam position sensor, air flow meter and manifold pressure sensor so has shut itself down.
Am I on the right track as have double and triple checked everything and nothing should stop it from running. Even gone to extent of manually bleeding a self bleeding system.
Interesting one this so any ideas welcome!!
Thanks.
