Hi Listers,
I have now changed the sooty plug and going for a test drive tomorrow. It was
definitely sooty rather than oily. Regarding the PCV valve, I have installed a
rocker feed kit as sold by Moss and was wondering if that could be the cause of
a lot of oil being pushed through the valve and being dumped into cylinder no 3
causing it to make the plug sooty.
all advice greatly appreciated,
Thanks,
Chris

. I would also check the soot
on the plug--does it feel dry and fluffy, or oily? If the latter, it's
time to do a compression check. If the former, the plug could be firing
intermittently, or, there might be a slight vacuum leak at the manifold
at that cylinder.
