Polished rocker

Been doing a bit of maintenance for the saloon and preparation for the GT6 by servicing up a couple of sets of rockers for the six cylinder engines. A problem I had been having with the saloon was accurately setting the valve clearances; this was in part due to a slightly worn rocker shaft, but largely due to the worn faces of the rockers.













New rockers are available, but seeing as I had the time and inclination, I decided to service the ones I had. First off the shaft was stripped down and the components left to soak on paraffin for a couple of hours before being scrubbed clean using a wire brush on a drill and any oil ways cleaned through. The ware face was then carefully polished using WD40 on 600 grade glass paper, taking good are to alter the polishing angle as I went along, to maintain the radius on the face.
The rocker assembly was then re-assembled with copious amounts oil on a new rocker shaft.















Back on the saloon after the clearances were set, the valve train sounds a lot quieter now, so a successful job then, which was then proven with a trip over to Carmarthen to have a look at a MkI GT6, the new owner of which has also started a blog.
