[vitesse 6 running on 5]

I have swapped plugs and leads about to no avail. The wetness is definitely oil not petrol and the firing order is correct. I will check the valves as soon as I can. Thanks again. Russ

Checked the distributor today and there isn't any wear, all plugs firing. Number 6 is oily though but all the valves are seating correctly. Compression test showed slightly higher in number 6. Also did an air leak test on 6 and could hear some leak through the dipstick. What else can I do? Russ

It is number 6 that is not firing and it is pretty constant. I will try the distributor tomorrow and check the points. Thank you all for your help. Russ

Thanks Pete. Air leak check was ok, tappets adjusted and plugs changed more than twice. I was thinking a piston ring had broken. Running out of ideas. Russ

Hi, I have a 1965 vitesse 6 that is running on 5 cylinders. I have changed plugs, leads, distributor cap and rotor arm. I have done a wet and dry compression test and all is good. The next thing to do is remove the head unless anyone has got any ideas? Would the piston come out top or bottom without removing the engine? Yours hopefully Russ
