    Engine/big-End Failure?

    Hi guys, cheers for that, yeah unfortunately it's going. I've had 2 other people contact me directly, they've had failures very similar, so I'm starting to think the VM Motori 2.8CRD's might have a bit of a flaw in them. That'd explain why others have had a lot more out of theirs with the Petrol or different engines. No more GV's for me for a while, going to a Zafira (I know!) as need low mileage and something cheap to run/fix, not nearly as interesting as my old GV though. Sorry @@BumBle02 I've not been back to my parents yet where the GV is sat looking miserable on the drive, when I do I'll get you the o-ring sizes for pickup, there were definitely two O-rings on it though, one just visible when installed, the other inside the fitting.

  2. Ok @Admaalzo66 Ok I take that your Fuel Filter been changed recently, if not change it b4 you will do anything else. 1. Remove the plastic engine cover x3 10mm 2. Buy or get ~0.5cmx 1,5m or longer hose 3. At the end of the Common Rail pressure pipe undo the return hose and try to block it with a screw for example. https://www.youtube.com/watch?v=m5FnOU4MiIQ 4. If you on your own you will need long hose - Connect your hose to the return valve ... and put the other end to the bottle (secured place to avoid silage). 5. Start cranking engine as you do (in the morning pref - on cold) and watch if there is any fuel going out of the return valve - if yes - replace the valve at the end (Bosch only) ~£50 - £60. 6. If no leak on cranking or running engine, try to rev it to 2.500k (max allowance on P gear) and watch if the valve is letting any fuel or not if yes replace if not go to no.7 7. Remove inlet pressure sensor (Bosch part) 4 pin plug x1 hex nut bolt - its in the inlet not far from the common rail (ref. to the picture attached) 8. Use brake cleaner to clean in from any deposit - refit and test the cold start on car after few hrs. 9. If not any better, buy new sensor (Bosch I paid ~ £25) Also good tip to improve cold start is to buy set of new glow plugs, they are cheep as chips these days £10 each all you nee id long 10mm socket to replace them. You need to remove alternator to get to the 1st glow plug. Hope this will help. Good Luck
