rogerowen Posted August 10, 2019 Report Share Posted August 10, 2019 Is there a preference for sealing rocker cover gasket? Given that the rocker cover is going to be on and off several times in the near future - I'm thinking of temporary seal with grease as opposed to my normal Blue Hylomar practice. ???

Drewmotty Posted August 10, 2019 Report Share Posted August 10, 2019 I use Welseal between the cover and the gasket to keep the gasket captive and a light smear of grease between the gasket and head. Tighten the nuts only just enough to take up the slack and not over compress the gasket or deform the cover. Quote Link to post Share on other sites
RogerH Posted August 10, 2019 Report Share Posted August 10, 2019 Hi Roger, as above but I would put a smear of silicon sealant on the cork/head interface. Easily removed and renewed. Roger Quote Link to post Share on other sites

I have an ally rocker cover that does not have any type of retainer for the cork gasket, years of never quite getting it sealed, as any degree of tightening, just caused the gasket to slide, later, I made a plywood jig. With an inset, now I fit the cork to the ally with well seal, nip down and leave overnight, grease between cork and the head and no issues. John. Quote Link to post Share on other sites
Drewmotty Posted August 10, 2019 Report Share Posted August 10, 2019 We have a tame machinist in the Devon Group who can machine a groove in alloy rocker covers to take an o-ring seal. Quote Link to post Share on other sites
Lebro Posted August 11, 2019 Report Share Posted August 11, 2019 I stick the gasket to the head with welseal, & use grease between gasket & cover, no leaks, & it had been off & on several times. Bob. Quote Link to post Share on other sites

Graham Harris Posted August 11, 2019 Report Share Posted August 11, 2019 I use contact cement to glue the gasket to the cover and nothing on the head side and it has never leaked a drop. Graham Quote Link to post Share on other sites
ctc77965o Posted August 12, 2019 Report Share Posted August 12, 2019 I stick the gasket to the rocker cover (after giving the sealing surface a good clean) then lightly oil the head surface to stop the gasket sticking there. Now when I remove the rocker cover the fragile gasket/cover can be safely placed out of harms why whilst i fumble with my feeler gauges around the engine.. Quote Link to post Share on other sites
