Head gasket sealing?
Dazza215:
Ive just rebuilt my top end and didnt use any sealant on the head gasket. I torqued it down as stated in the book and it seems fine.

I have rebuilt dozens of engines and never used any sealant on japanese motors except for the odd rocker cover where some models have no gasket and of course the mating crank case faces where I use blue Hylomar. I have never had an issues with leaks on any. I do grease paper gaskets, I know there has been loads of discussion on this, but I find it makes them more pliable and less likely to be damaged and also keeps them in place when fitting. I don't see the point of using sealant on rubber gaskets at all and can't understand why you would do this..

Hi neilg, I'm just asking the question as there are loads of different views and methods out there. I did not use anything the first time and had no intention of the second time but after searching for answers I came across a load of people using copper slip and sealant with good reviews, so I asked here on this forum as it's been the bible of information for a first time builder like me. Thanks for your 2 cents.
