A: Oil Pipework Fibre or Dowty washer?

Has anyone tried a Dowty washer instead of fibre washer 448 where the T30AS oil filter assembly screws into the oil tank. I don't have one to hand to make a judgment . It could be an upgrade giving a more positive location.

Thank you, V B.

I’m a newcomer to Vincents but I’ve started using Dowty washers on my Rap banjos without a problem (yet). I don’t think I’d hesitate to use one on the connection to the oil tank when the time comes but I as I implied, I have little experience and I may well be shot down by our more experienced members.

l have been using dowty washers for years without any problems or oil leaks for that matter! They can be used several times over before you start to get a mist around the joint which basically means time for a change. On the rocker feed pipes fit M6 dowtys instead of the copper washers but retain the fibre washers between heads and pipes for an oil tight joint. Buy on ebay in bulk for the best deals.

The French Dowty seals I find better as the rubberized portion covers over the steel washer further or make my own style with an "O"ring in-cased in a very thin S/S or aluminum parted off shallow pipe rings. Most of my oil quills are undercut in the lathe and an"O"ring fitted, same as sump plugs. All being drilled across the flats to fit a short length of s/s Morse control cable bent in such a manner as to clip behind something utilizing the tension in a tightening direction. Omega style clips I find useful for wiring pairs of bolts like the rear bolts on petrol tanks or under series "A" tanks. It is far easier to re-wire things up again. Cometic gaskets I consider very expensive when lapped surfaces are done to both sides a paper joint or a smidgen of sealant does an equally good job. My rocker caps have been "O"ringed since before leaving the H.M.Dockyard Devonport 1968.

Bruce, thanks for that, unfortunately all l get is a blank page? Marcus, l understood everything up to the morse control cable and omega clips? Any chance of some pictures? Like yourself l can cope with gaskets, sealants etc but they can be time consuming and these days l would sooner ride than work so if these cosmetic gaskets save me workshop time like dowty washers, french, english or whatever l could well be interested. As for being "o" ringed since you before you left HM Dockyard Devonport l cant say l am surprised! Yours puzzled and braced for a salty reply of West Wales..................

Marcus, as you were on the morse cable ie lockwire but still intrigued re the omega clips? Yours only slightly enlightened of West Wales..........
I thought about what Marcus meant by the Omega clips. That would be a piece of wire shaped like the greek letter Omega. You can insert one end of the Omega in a hole in one bolt, one in another and it will lock both. I have my tank bolts lockwired togehter because you can't have those tight. Whenever I take the tank off I need new wire. If I had his clip I could re use it.

Bruce, l did indeed click on the orange rectangle and f, nothing happened, oh poo! Craig, thank you for the information which both fascinates and intrigues me, however l have but one question which is, wait for it, if fitted dry ie no grease or oil on mating surfaces do said gaskets stick and then self destruct or merely separate from said surfaces in one piece? If the latter is the case l can indeed see some of my state pension going to a worthy cause as the arthritic hands are fed up with faffing about with poor fitting gaskets, sealants and my short mental fuse is often in need of a reset after finding oil seeping from whence it should not. Clearly l am not the only person a tad confused by the omega ring, even a google search failed to clear the brain fog that had descended like a cloud before my very eyes. When l made an enquiry with a son who is employed in the motor trade he suggested that perhaps the said ring answer might be found on one of the various adult sights that infest the internet? l have therefore decided to await a definitive answer from ringed of Devonport, over to you monsieur Bowden. Yours cosmetically enlightened of West Wales at an unearthly hour thanks to spring lambing time, oh the joys............

Old Bill, the Cometic gaskets are just what we need. They don't stick and can be used over and over with no issues. There must be some limit, but if one has their timing cover off and on that often, there are bigger problems involved.

When I installed my timing cover gasket, I renewed the rubber seals for the cam spindle oil feeds because I had been using only Hylomar for that joint and didn't want to risk leaks between the spindle end and the rubber seal, due to compression.

Graham, Bruce, Craig and not forgetting Greg, thank you all, a cloud has been lifted and l have seen the light and hopefully no bloody oil leeks! So..... how do l get hold of said gaskets in the UK ( well Wales which is sort of the uk ) Yours shivering on a hillside in West Wales..............
