Hi I need help, I have just changed the Camelot on my xf jag all working good took it up the motorway for a test drive got up to speed then it coughed and spluttered then stopped . Won't start again , got it recovered home , thought it might be the belt  so I stripped it down again to check-out the timing marks, all as it should be, any ideas please.

Hi Nigel,

 

It does sound like a fuel problem.  I am guessing that your car is the 2.7 Diesel, and there is a process that has worked for others who have had a warm start problem.  Look up Terraclean on google.  Tis is a process that cleans out the fuel system etc and did a good job on my car.

 

Let us know how it goes.

 

Peter.

Hi Peter a bit more serious, had a guy look at the car seems to be an ECU fault ,coming back with better software  hopefully will sort out problem will keep you posted.

Hi update on the car even more serious found out that the crankshaft sprocket had moved and chucked the timing way out not sure if the engine is valve safe looks like the heads have to be removed big job will  keep you posted.

Ouch, hope it doesn't turn out too bad for you. Fingers crossed.

:(Cheers Colin spoke to the mechanic Friday when he comes back Monday he is going to reset the crank and timing marks where they should be and recheck the compression if the readings is high then I have got away without valve damage my engine bay doesn't  look very pretty at the moment.

Update on the xf took the cam covers off today not a pretty sight some cams have come off the valves on one side and all the followers are loose.that's one side the other side same again also the cam chain has snapped and gone missing cannot see it hopping it's in its recese and not gone down in the sump not good at the moment

Hi Nigel

As owners and drivers, I think we all feel your pain, let's hope it doesn't get any worse. As Colin said, fingers crossed, and good luck.

Steve

Hi Nigel,

 

I hope it gets sorted out for you and the worst scenario does not happen.

 

I know the feeling as it happened to me once  ---  but the saving grace was that it was a company car!

 

Good Luck,

 

Peter.

hi peter it isn't a company car. I wish it was. I just hope I can find the chain  lol ,

sorry to hear off your problems with your car nigel. modern cars nowadays have electrical problems, and the hand built cars are the worst. really hope that you can get t fixed and not to much cost, liz x

hi started stripping the engine down , lucky I have found the chain, but valves are bent . camsharft  holders were loose with a broken bolt some cam followers are broken and floating around the head  not a pretty sight. I have got 2 replacement heads coming so will help I think what was a repair job is now a project, keep you posted,

all new bits have now arrived ready to rebuild the engine does any one know  if no 1 piston should be at tdc or before tdc  It doesn't tell you in the manual even called local jag dealer they don't know also went on the net can't find an answer it  is a 2.7 diesel  i appreciate  a quick answer .cheers

Hi guys car is all back together and up and running , I can now say it was the biggest car job I have done in the 40years I have been working on cars, there was a bit of name calling at times, due to the fact some of the components was hard to get to because of the confine space in the engine bay, I was lead in it sometimes not a pretty sight, I was told by jaguar they would have taken the engine out and replaced it with a recon one cost over £4000 , it cost me £1500 and gained at lot of knowledge of the 2.7 diesel engine, and also a lot of back ache , would I do it again, no. Cannot wait to Finnish putting last bit of trim back on and using it again. Still the best of all the jags I've had.

Well done Nigel

im sure she will have been worth the back ache
