Car stored for many years and only recently back on the road, fluids changed and engine running nicely but mechanic thinks it has a sticking exhaust valve diagnosed from the right hand exhaust occasionally sucking. It can be heard also.

Car has only tootled around on slow but lengthy runs since emerging from the dark and is due a check over as well as the timing and clearances checked in two weeks.

Now he has said a good thrashing sometimes releases them but i;m not overly keen on doing this until I have changed the HT leads and spoken to you guys in the know.

It is booked in to one of the respectable speed six garages for the timing etc to be checked but I like to get my hands dirty so any anything I can do in the meantime to help investigate I am happy to do.

Any thought other then new plugs, HT leads, coil pack?

I would check the clearances first. Maybe the gap on the outlet of this cylinder is just way out so a corrected shim will help.
