Tappet chest breather

[surfergirl]

Hi folks,

Just been cleaning the covers for the tappet chest on the van engine ready for fitting to the recon. The cover with the breather pipe has a very narrow slit and almost looks like its been squashed, so I pulled one off a spare engine. This one has the pipe going all the way through, so probably from a different age engine?
Heres a picture, the one on the left is what came off the 1098 engine Im rebuilding, on the right is from a spare 1098 engine.

Any help would be great.
Cheers.[frame][/frame]
Also the dimples on the front of each cover are different.

I think that the "2 Rump Steak meals for £15!" offer is so far out of date now that they'll never accept the advert.

Hope that helps!

Either will be fine - as long as the pipe is clear. Later ones use a rather better rubber seal, but the early cork seal is ok too - just don't overtighten the bolt - which is what collapses the cover!

Thanks for that, I did wonder if covers had been fitted from another A series engine (mini) thought it might rub on the push rods and make a mess of the nice new engine.

Up to date steak for two vouchers are in the post tomorrow! Only valid at Lands end Cornwall.

given a choice I'd use the one with a baffle plate, but not sure if it would make much difference compared to the straight through hole.
