Hi Guys
any pointers on this ?
had one injector chuffing away, so pulled it out, re seated, new washer and re-assemble, that went ok
started her up, fired up straight away, made small rattle sound,so turned off, tried to start again and just turns over, wont even try to catch. tried some easy start as though maybe just needed to pull diesel through as been off road for 2 months wont even run on easy start, sometimes it will try but just for a split second.
put the clip on and have a few errors,
DF019 - flow sensor circuit - I have the MAF & air box disconnected DF022 - Ait temp sensor circuit - CO1 - old fault DF052 - External Temperature sensor - CC - again think this is old fault but comes back after clearing DF085 - Water Temp - CC - old fault like above, Pre heat relay circuit CC1 - this is an old fault and always been fine with this even in cold weather
I did have to charge the battery as went flat being left standing for two months don't think it holds charge like it used to, its probably 3 years old now at least
checked the following via clip
Pressure in gallery 4 Bar - thought this should be higher ? rail pressure loop variation 298 Bar gallery pressure valve RCO - 5% engine speed when cranking varies between 220 and 280 RPM, sometime with easy start is tries to catch and RPM went to about 1500RPM
Not sure what the RPM on cranking should normally be so removed TDC sensor as known problem not very dirty, but cleaned up and refitted, but no change in recorded speed
when switch ignition on you can hear the low pressure pump run, and also you can hear the fuel running through the high pressure pump , would this be normal ?
reading through old posts someone said cambelt slipped on theirs, would have thought I would have got error for TDC + cam not matching up
also wondered about high pressure pump, but would have thought would have run a bit on easy start
any pointers for me to look at ?
cheers

Cheers Brian It sometimes did smoke on start up but after a quick burst it would settle down to be clear as I said its very thin oil, mixed possibly with diesel though it could be there was only a small amount of oil and its mostly diesel and its just picked up the oil that coats the inside of the pipes If it was oil coming from the turbo would it be thin like this ? or just normal thickness don't really want to scrap it, love it too much even though its getting a bit ragged round the edges I was thinking about cleaning everything out, suck out anything that might have gone into cylinders (oil etc) fit new gasket set and 2nd hand injector and then see what happens, that's about £60 so not too bad if still no good got covered in it when I took the rocker off as I lifted it off and turned it over to look inside for any cracks etc and it poured all over me ! think it was in the expansion box part of the cover (rectangle shape at the front) there might have been more than 1 pint in the intercooler pipe, so don't think it would be able to suck any air will try and look at it again tomorrow Age

cheers Will clean the cover up and check it properly hopefully this should be links to the gasket damage and the damaged injector am wondering if the tip on the injector was damaged or blocked and the pressure blew the end off and I guess that might have been the rattle sound I heard when first started Its certainly a big hole in the end of it now , and you can see the needle http://i186.photobucket.com/albums/x199/ab9000/injector.jpghttp://i186.photobucket.com/albums/x199/ab9000/gasket.jpgjust noticed there is a dent near the tip of the injector, see photo below I'm not sure if it was there before I refitted or not. http://i186.photobucket.com/albums/x199/ab9000/injector2.jpgI remember when I took the injector out I rested it on the slam panel, and forgot I did then it started to rain so I closed the bonnet (not slammed but I think I did push is closed properly on the latches) so I could have dented it then, maybe causing a fracture to the tip which then blew off due to pressure or maybe there is a damaged valve which then hit the injector If a valve was snapped I would have thought it would be very noisy on turn over, where as it seems fine. not sure if I should go the whole way and get the head off as well, though don't fancy all that
