Smoke and Mirrors


Then I inspected all the various parts of the head to see what could be causing the smoking problem. I found many things wrong. The smoke issue seemed to be caused be wear or carbon build up on lots of components with the accumulated result of poor combustion rather than any single point of failure.


The rockers had bad wear in the pads. These are meant to be smooth and should not have holes worn in them like these


The valve stem tops had grooves worn in them as can be seen from this photo that shows one of Annies original valves:

The valve stems also had significant carbon build up on them as well as shown here when compared to a brand new valve.

otherwise setting an accurate valve gap is impossible


I used a valve spring compressor to remove all the valves from the head in order for me to inspect the valves and seats. The valves, springs and collets were placed in freezer bags and labelled for future reference.
