I registered my Navigator yesterday so it is street legal for Germany!
Today I made a 10 mile test ride. Stopping for a nice photo spot I noticed oil all over the bike. So no photo but going back to my workshop.
Oil is coming from the cylinder head ( I guess). I used a cooper head gasket and it needs more annealing. I torqued the heads already after some enigne idling till it was warm.
Will pull the headsand birng the gasket to the local blacksmith for heating so it gets softer.
I wanted to take the bike to a meeting on Sept 21th so ordering a new composite gasket through NOC will take too long.
Now I know what the styling panels are good for: preventing the oil from splattering over the rear of the bike. Clever engineering!
Hi Ulrich, you have my sympathy after all that hard work but don't be put off, once it is sorted and run in a Navigator is a lovely bike - and yours is looking immaculate despite the film of oil! I seem to remember you have had head gasket blowing problems in the past so it is natural to suspect the oil leak is from the gasket - however I would carefully check the rocker oil feed pipe, it's banjo joints and the rocker box gaskets first - they are all prone to leaking. In my experience a leak from any of those areas can trickle down between the heads and then appear to be coming from the head gasket. I apologise if that is stating the obvious but it might just save you a lot of work and the cost of another head gasket! Good luck with finding the source and cure - it may take time but it can be done!
Hi Uli, good to see it’s nearly there, I echo Nicks comments about checking the source, it took me ages to find where mine was coming from, which was a combination of the rocker covers and banjo bolts.
All the best
It was the same for me on my Jubilee, leaks from the banjo bolts on the rocker feed and the rocker covers. I needed gaskets AND silicone sealant on the covers. Also, i found one or two new stainless cap screws on the rocker covers were bottoming out before they pulled tight on the gasket. Either they were a thread or so too long or the threaded holes were plugged with dirt. I used a parallel tap to clean the hole threads and a washer under the cap bolt heads where necessary.
I agree that a head gasket leak is unlikely to be the source of so much oil and I would look at banjo bolts and rocker covers first.
