engine side covers leaking.... any tips?

[Grahmo]

Hi

Firstly let me thank you all for your help with my master cylinder back in the February. In the end I had to replace the whole unit, which turned out not to be as difficult as I thought it was going to be. I just followed the guide in the technical tips section.

My problem this month is I am trying to fix all the engine oil leaks (no small task lol). I have managed to seal up pretty much everything with new cork gaskets, except the two inspection plates on the side of the engine. I have tried cork and plastic gaskets and the last time I did them I used cork with instant gasket on both faces. However oil appears to be coming out of the holes where the bolt goes through. I have tried flat washers rather then the shake proof star ones that were on the previously but still no luck.

Should there be some kid of seal fitted to the head of the bolt or something like that - oh and how tight should the bolt be? I know if it is too tight the gasket squashes out of place.

How do other people get the plates to work, is there a trick I need to know?

The bolts should have concave shaped washers fitted that hold rubber 'O'rings, preventing leaks. The bolts should be 6 ft lbs I think, not very tight.

Thanks les, that has got to be the quickest reply ever!
Looks like I'm going to have to track some of those rubber washers down.

ESM sell both the washer & the seal (other parts suppliers are available)

Yes, this works, get the rubber seals fit them and the tappet chest covers will stop leaking.

But in general - make sure the engine breathers are all clear - and one is connected to the carb. If there is any pressure in the crankcase the engine will leak oil 'everywhere'!
