You will need to put a micrometer onto the cam lobe and see whether it has been worn down below the minimum specified value - which I haven't seen on my CD yet. If it's below then the cam isn't pushing the valve in far enough or for long enough which can understandably give bad running problems.
Would cam wear give low values on a compression check ?
To see worn cam lobes, check out my posts in the 145/146 forum in the http://www.alfaowner.com/Forum/alfa-...-2500-rpm.html
thread, some VERY close up pictures of the damage there. Any sign of a tip forming on the lobes and they should really be replaced.
Cam wear causing low compression, well in theory, yes it would if the inlet cam was worn, not opening the valve long enough to let the gases in, but if the exhaust was worn too, then that woldn't hold open long enough to let them out son also in theory they could balance themselves out and actually give the correct reading.
On the plastic top engine it's only 16 bolts to get the cam cover off and no you shouldn't need a new gasket, these rubber ones are quite reusable.
I had mine done and got 165-175 psi on all four. I did notice that the mechanic took the plugs out one at a time whereas I have read in some procedures instructions to take all four out and then measure each cylinder - can't see it making any difference myself ?
Just for info I just had the variator changed on mine. It now goes 10 mph faster (about 120 mph from 110 mph) and revs a bit better from 3-7 k but it still has the symptoms catalogued on my thread. It will redline in 3rd but is reluctant to go from 5-7k and won't go beyond 6k in 4th.
I agree with Smaky on this kangaooroing problem being a mechanical issue (rather than electronic/sensor) after I swapped all the electric stuff and the ECU and found no significant improvement.
The belts and recent variator change plus swap bits from the breaker have now cost me well over what I paid for the car. Cams from the breaker and labour will be another £300 min. Cheaper to have fitted an engine from a breakers ?
My latest thought though and as you'll have them out anyway to check the cams, is the coil packs and leads/boots, any cracks in the plastic and they'll arc to the mounting plate and loose power, any damaged or broken down leads/boots and they to will lose energy and give a weaker spark, but because the CF3 engine uses the same coil pack on the primary and secondary plug of each cylinder an earthing pack will be more prominent than on the CF1 or 2. Again there are VERY close up pictures of what you are looking for in 2 other threads... http://www.alfaowner.com/Forum/alfa-...uestion-4.html
