Cam Belt Query

Can you screw a couple of self tappers into the body of the seal and lever/pull the seal out by using the screw heads?
Quite possibly, I've watched this today demonstrated on youtube vids, looks like a possible method. I haven't got the sprocket off yet though and can't see it very well. I'll update when the now heavy rain goes off. (I'm doing this on my drive)
 
That was the way when the seal had a metal outer core.....these aren't too common now - at least on cam shafts - so generally they can be gouged out. For some reason unknown to me, a metal cored seal always appeared on bike engine gearboxes where the final sprocket drive was.

Ok, here's some pics of the end of the cam, I'm convinced it's the cam seal rather than the rocker cover gasket, I got a new one yesterday so what do you think? The end face of the engine is not exactly dripping with oil, but it's definitely seeping out of somewhere! Sorry about the camera angle.

It has to be the camshaft seal really, although its hardly worth worrying about.....its called 'misting' rather than leaking.
Most folks would leave it be but observe it from time to time.
Its not a metal shrouded seal so it should pick out, once everything is cleaned. Once you get stuck in though, there's no turning back!

Heh, not sure whether I'll bother now, I'll ponder it while I'm doing the water pump. The face is quite oily, but like I say it's hardly flowing out. The timing belt is in surprisingly good shape, no sign of oil contamination except for a splodge which I'm sure I did while I dissembled it all.
 
That seal has been misting for quite a while and it won't fail all of a sudden. Try bending the belt back on itself, looking for the odd split - sometimes they show up, sometimes they don't. I've replaced many belts with no apparent wear at all, and some that were almost in tatters but they go back to the 80's when OHC belts were just coming in.

Ok, I didn't bother with the seal in the end, perhaps I'll have a look at it before another 10 years is up. Got it all timed up ok before the rain hammered down, just got to fit the new aux. belts when it stops. The engine mounting is a bit of a pain on these, it has the tensioner spring and plunger in part of it.

For anyone working on these engines, here's a handy link that I came across which is a good supplement to the Russek manual.

Sorry John, cross posting there, yeah the belt is pretty good, it's obviously been done at some stage since new. The water pump is showing signs of leakage though, you know that sort of crystally deposits.
 
Thanks for all your input everyone, I'm happy to say this job is completed and the motor is running very smoothly. Funny how they seem to go better after doing a belt when it shouldn't really make a difference! I suppose the belts stretch a little as they age which will have a subtle effect on the timing, but I bet it's mainly psychological. Thanks again.
