For the couple of weeks or so, I have noticed a faint whiff of burning oil. I feared it might be a leaking bevel box but there was no sign of oil there. It was actually very simple, the rocker box gaskets have gone rock hard after 7 years in the heat and sun of the south of France and are weeping onto the cylinder head sides and the downpipes. My M3W is going into its winter hibernation on Sunday, so it can easily wait until next spring to be done. I have loosened and tweaked up the hex socket screws on the rocker boxes and that has reduced the leak to the tiniest amount. As I am going to be in Baltimore, MD over Christmas, where there is an S&S dealer, (Kundratick Kustoms), I have ordered a gasket kit from them (part no.106-0622 from my 113 X-Wedge parts book). I will pay him over the phone and get my daughter to pick up, as I suspect they will be closed between Christmas and New Year, which is my stay.
As to a jointing compound. I have a choice of RR Hylomar Aerograde PL32 Medium, Loctite 518 Anaerobic Sealer or Pro-Seal high temperature silicone black. I would lean towards the Hylomar, which I have used for race engine building for the last 50 years, everything from 1430 Cooper S engines up to 3.0L Judd CV8's. Any opinions folks?
PS If anyone wants a copy of the 2019 parts book, I am happy to send them a PDF.
