Oddball Posted May 11, 2020 Report Share Posted May 11, 2020 Hi All Ive had a search for an answer to this with no luck, so I’ll have to ask. I have an early (20 year plus) rocker cover from Racetorations that was originally fitted with a flat cork gasket. The current offering have a rounded channel that takes the newer O ring seal. I’ve spoken to Darryl about this and said he would let me know if he had any cork gaskets left, however I’ve heard nothing so assume he hasn’t. Before I have a go at making my own, has anyone had a similar problem. Thanks Cameron Quote Link to post Share on other sites

Steves_TR6 Posted May 11, 2020 Report Share Posted May 11, 2020 Interesting i have a 1990’s racetorations rocker cover which came to me with a leaky cork gasket, Darryl supplied a new o ring gasket which has been good since 2012. steve Quote Link to post Share on other sites
Oddball Posted May 11, 2020 Author Report Share Posted May 11, 2020 Interesting indeed. When I spoke to Darryl last week he wasn’t confident that the O ring would work with the flat grove. Obviously from you experience Steve, they do.I assume the O ring won’t sit in the flat grove and you just have to carefully watching its position as you tighten the cover down. Thanks for your help Cameron Quote Link to post Share on other sites
PodOne Posted May 11, 2020 Report Share Posted May 11, 2020 Can't see why a "O" ring gasket would not work not real pressure to deal with. For added peace of mind why not run a bead of silicone in the channel then the "O" ring? Andy Quote Link to post Share on other sites
Steves_TR6 Posted May 11, 2020 Report Share Posted May 11, 2020 I stuck mine in with some silicon gasket, left to dry on a flat surface overnight. lightly oiled the mating face before fitting the next fay so it didnt stick All good so far steve Quote Link to post Share on other sites

Thanks Cameron The cork gasket that was originally fitted to the pressed steel cover how different is that to Darryl's cover design? if it is, can it be modified to suit? I have one of his later covers with the rubber beading. You can buy rubber beading of different sizes, you may be able to adapt to suit! My cover gave me a lot of aggro by leaking from the neck area. To his credit he tried to sort that problem out, in the end I had to sort it out by a redesign the neck fitting and filler cap. Having done that it then suffered from porous casting and then had to be vacuum sealed. I have had no problems since. I have now noticed that the whole cover has been completely redesigned! It looks to have gone over to the old SAH design for the filler area and machined out of solid. Bruce. Quote Link to post Share on other sites
Keith Warren Posted May 12, 2020 Report Share Posted May 12, 2020 Hi Cameron I have one of his late 90s with the rubber O ring seal for a thin cork have a look at the TSSC shop they do one. Keith Quote Link to post Share on other sites
John L Posted May 12, 2020 Report Share Posted May 12, 2020 I don't know the size of the Restorations cover. Is the Restorations cover the same dimensions as the old pressed steel gasket?, Rimmers and Moss do a Silicone rubber gasket that fits the size of the steel cover and is shaped to fit it, and has worked well for me as you can take the cover on and off many times and does seal well, without too much pressure from the 3 mounting nuts. https://rimmerbros.com/Item--i-GEG413URT John Quote Link to post Share on other sites
Oddball Posted May 13, 2020 Author Report Share Posted May 13, 2020 Thanks again all, the Other gaskets mentioned above do not fit the Racetorations cover,I did look at the Rimmers one at Stratford last year and it was much wider. My only concern was that Darryl wasn’t sure his current O ring gasket would work with the older flat groove covers, however Steve has found it can seal reliably. l’ve ordered one, however there out of stock, so could be a long wait.

Cameron Hi Cameron As a stop gap you could try buying some silicone tube of the right diameter and making one by super gluing the ends together? Andy Quote Link to post Share on other sites
