sparky_spit Posted November 6, 2009 Share Posted November 6, 2009 Payen gasket, ultra clean faces, and a light smear of blue Hylomar just around the oil feed hole for the rockers that goes through the head/block interface, on both sides of the gasket.

GT6 M Posted November 6, 2009 Share Posted November 6, 2009 Not wanting to dismiss the above, Ive done that, and it still leaked oil out the front alot,so last time it was off,thought I,d try some thing else, ..black silicon mastic.. went on the front, and at the oil hole at back,no leaked yet { any one stop gasket silicone will do, ]the gaskets witht the shiney gloss on them , is supposed to be a glue, that melts when engine gets hot, so sticking the gasket down, , so the manufacturer told me,but it never seems to get hot enough to melt it, and if it does, its only in places, and no all over, , and where it sticks, Its hard to get off,I think the grease and oil info, came from the time when they were all metal / copperand this acted as a kind of sealregards Marcus Link to comment Share on other sites More sharing options...
Steve Cureton Posted November 7, 2009 Share Posted November 7, 2009 I use a thin smear of Hylomar sealant all over both sides. It doesn't hurt anything (that I'm aware of) and can only help. I've replaced several heads in this way without problem. Link to comment Share on other sites More sharing options...
Deleted User Posted November 7, 2009 Share Posted November 7, 2009 I am with Sparky on this one, Just done this and the car ran really well today going up to Oulton to see the other chaps take in a few laps.No leaks. Just remember to re-torque after a hundred or so miles.Rob Link to comment Share on other sites More sharing options...
