Pete Lewis Posted October 27, 2023 Report Share Posted October 27, 2023 the best part of having an alloy cover is it takes on engine heat better doesn't get cooled by the fan and hence does not attract the forming of mayonnaise which you will get with a tin cover especially on short runs the old gag in the 70s to stop this was to ,either ,,lag the cover ,make a air flow baffle at the front, remove the fan i just dont see the spout outlet being any problem if you use a filter or hose it to atmosphere rocker gaskets have over the many years have always been a risk of leak due to poor seal retention or other misplaced seals be they cork. neoprene, composite or what ever its the nature of sealing a nasty tin cover in an oily environment its not something you need to remove monthly ,maybe not even annually depends on mileages. triumph tin covers have no gasket retaining lugs or positioning aids what ever you use its a high risk leaker design the alloy flat face and thin gasket is or should be a better bet Pete Pete Link to comment Share on other sites More sharing options...
Straightsix Posted October 27, 2023 Report Share Posted October 27, 2023 I have bought the neoprene gasket for when I get around to checking the valve clearances, is the gasket fitted dry or use a smear of sealant. TIA Link to comment Share on other sites More sharing options...
