| Hi,
I have always used cork gaskets which I don't have a problem with. When using cork gaskets I have always covered in oil as I believe this encourages to expand to form a seal.
I have dug out the gaskets pictured here:
I don't think these are cork (although I could be wrong) so what is the best method for sealing?
Thanks in advance.

| Cast alloy rocker covers (from JR Castings Ireland, jrcast.com) with silicon gaskets from the "Real gasket Company Tennessee"(https://realgaskets.com/product-category/automotive/saab/), leaking rocker covers solved!

| Thanks for the replies!
I知 definitely going to treat the 96 to cast covers at some point but as this 95 is not a keeper I知 putting it together with as many bits as possible that I already have to manage the budget. I値l use some hylomar and I知 sure we値l be good.

| Make sure that the mounting screw holes in the covers are flat in that area. Over tightening over time bells them out and then it's difficult to get a good seal Screws only need to be a bit over finger tight. A few taps with a hammer onto a steel rod anvil will sort it. You can get triangular plates to fit under the screws that spread the load. These commonly used on American V8's and not hard to find. Make them yourself if you are handy and have time on your hands.  | |

| I dislike the alloy rocker covers (have to say they're beautifully made though!), so I need to make do with the pressed steel ones. I'm with Derek, I always tap them flat with a panel beating hammer on a block of hardwood. I've used the spreader plates on some engines, but to be fair I don't think they're really necessary. I give the gaskets a smear of ordinary cv joint/ ball bearing grease and I hardly have any issues. I've also used the silicon gaskets, but I find they're hardly any better than "cork" ones if the covers aren't flat. The gaskets in Gareth's pic are a rubbery synthetic product, not sure what it is, but much more durable than old-fashioned cork ones. If they're Payen or Gaskets for Classics made from Reintz material, they're very good quality.
