Informative thread , very interested to see recommendations for high temp copper silicone Loctite 5990 for head gasket installation. ( Am at a copper composite head gasket on a side valve engine , bigger than a sevenĀ )
I note to apply thinly , presumably one still needs a complete coat ,what does anyone use to apply it / spread it ?
I would be afraid of excess 5990 squeezing somewhere it shouldn't ,when torqueing down !
I'm guessing best approach isĀ to lay the gasket down & apply the 5990 to the block side of the gasket & also to the head ?
Presumably one needs to be reasonably quick doing applying the 5990 & torqueing down , as you don't want the silicone starting to set up ?
Interested to get any tips .
