Right time to bring you all up to speed on this. I have got to the bottom of the really bad running.

Cambelt was 2 teeth out on two cams, 3 teeth out on 1 and the last one was 4 teeth out!!! how it ran at all I'll never know. All reset now and re-did the compression test and all is fine. PHEW!!!.

However I still have a couple of issues. I still have two fault codes
MAF and Air intake sensor. I've got to pick my new MAF sensor up on Monday but I have replaced the air temp and it's still there.  :'(

I'll wait for the MAF before I start chasing wires could the MAF cause the ecu to flag the Air temp as faulty?

The other problem is the car still wants to idle at 2k rpm. I have traced this down to ICV valve being 100% open all the time. I swopped it for another one but it did the same. If you squeeze the ICV hose the idle starts to drop and you can get it all the way down to 600 rpm. So it's not air leak related, for some reason the ECU is telling the ICV to open right up. Now could this be because of the MAF or do you think something else has now gone to poo?

I am sure if your timing was 3-4 teeth out you would have bent valves  :o

I can, And did. ;)  I can vouch for the fact that the 3 litre can run when 4 teeth out at the cam sprockets without bending valves :y The symptoms  this car was displaying were very similar to my own experience.

 Have you found out WHY it jumped?

Yea. I found a ball bearing in one of the camshaft wheels. As I have removed and checked all the tensioners and they are ok it could of only come from the previous belt failure. It was doing it's best impression of a hamster in a wheel bless it  [smiley=laugh.gif]. I'm just hoping the ECU I have fitted isn't duff now and causing the idle problem  :-[ :-[ :-[ but I won't be beat on this one underneath all the grime  there's a good car which doesn't deserve to be scrapped or set fire or shoot or driven into a lake ( I have thought of all these options to sort out my problems)

Thats exactly what happened to mine!  And I thought it was a one in a million chance :o

 Let both cases be a warning to anyone reparing a v6 after tensioner disintergration to make sure you find ALL the bits :y
