I would like to know the various preferences of which sealant/gasket goo to use for sealing joint faces, both face to face or in combination with paper gaskets for good oil tight joints of engine and gearboxes.
I have used the method of wetting the gasket and rubbing silicone sealant on,but I put the gasket in place and JUST nip the gasket up and leave it overnight and then fully tighten.After I fixed the leak from the lifter mechanism I now get no leaks from timing cover,driveside or gearbox on my Comet..John
I've got a leak from the lifter mechanism, I've read about making sure the cable is running at the right angle as it heads into the cases. Beyond that, what did you do to sort it, and do you know if the Comet solution works on a Twin?
Having found loose valve covers on top of the engine when I took the tank off (and making a special spanner to tighten them as they are very tight up against the UFM) the top of the engine looks oil tight to me, just a weep on the lifter mechanism to sort.
On my Comet the seals that go between the shoulder of the lifter shaft and the crankcase face were MISSING.Hence half a Torrie Canyon,the wifes boots were nice and shiny and definately waterproof
Russ does a mod for the twin which does not fit the Comet.If he does not have one then I have a spare(or maybe I'll use it to start a twin project)...John
I'll ask Russ - VinParts is my usual supplier so we'll see what the solution is
Many thanks John. I've dropped Russ at VinParts a note to see what the solution might me (and ask if the apprentice mechanic like me could do it myself).
Thanks for the guidance.
I've got some original valves, pushrod tubes, pistons, primary drive stuff and other engine internals that came out of my Rapide when Terry Prince did a complete overhaul if you'd like to add them to the valve lifter mod and start a twin project!!!
Oh - and I think I may have the original brake drums too - she got a new set of Shadow Drums for a birthday present last year.
Oh - and a bucket full of tatty original nuts and bolts.
That's almost a bike isn't it - put it on ebay and should easily get £20K
In my yoof it was red Hermetite & knackered faces & gaskets & ,surprise,surprise ,they leaked. Then instant gasket,effective but dangerous, Blue hylomar, effective on good gaskets/joints but too expensive. Quite a few others but the late John King got me back using red Hermetite. Cheap,effective,easy to get rid off. Follow the instructions & let it become tacky before bolting up. Dell Boy.
In 2006 I first met Peter Bromberg riding his super Vincent Twin at a Ducati specialist (GTec, Jeff Green) when he was on the trail of some of the threebond and I was there to see a Ducati. He had also been told that this stuff is the holy grail of sealant.
If anyone is stuck for it, try GTec (you'll find it on a google search) and e-mail Jeff Green - he may be able to help put you in the right directon.
