rocker cover questions

[Grant]

2 thing's, They are cam cover's, Rocker cover's are for Mini's etc

Also the seals are inbuilt into the covers so be careful, allot are failing now so a smear of a good quality RTV helps to seal them or they will leak when re-fitted

Paint wise, Plasti Cote is good stuff, Makes Hamerite look ****,

They don't have gaskets they are sealed with instant-gasket type stuff from the factory as Miles said, which obviously hardened after they torqued them down from the factory so refitting them may not provide a perfect seal again, hence the need for a small layer of more RTV on top of the original seal.

As above.

How they can stop making something that was never in use, I don't know

If the seals are shot, use some instant gasket. Just to echo the above.
