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 ....

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.
