Anyone suffering from poor performance from a V6 following a cambelt tensioner failure or after finding that the cam timing was 2 teeth out?
I think i have got to the bottom of why my project car is so slow, and its not just because the previous car was a 3.0.
If this has been seen by others I will write up a diagnostic how-to but its a bit long winded as its a case of eliminate every possibility and what you are left with means an oily weekend.

Just a wild stab in the dark, but maybe the balves on the passenger side bank may be slightly out - maybe 2 thou or so, thus a drop in compressiona dn a wildly varying vacuum? Probably just wants some new valves. Am I close? ;)

Now either that is a piece of deduction that would be impressive by even Marks standards.... or you 2 have been chatting!
I wonder which it is .... ;D
Oh and you want to pick up your voicemail! ::)

My 3.0 has had poor performance before and after a cambelt change and the original belt was out on the left bank of cylinders but when I replaced the belt I am pretty sure I got it right.

Can you do a vaccuum check, record the value at idle, then open the rear multi ram by hand and see if the vacuum changes.

I think I can see where you're coming from here. :'(

There's a couple of heads, with nice clean valves etc, on ebay at the moment

I wouldn't have a clue how to test the vacuum tbh :(.

Thats not a problem the old girl can still pick her skirt up if she has too, its the fuel economy or lack of it thats the problem ::)

Are you still down in Slough, Pete?
I've got a vacuum gauge if you want to give it a try.
