Sorry.

ran the bike again yesterday there still is a very small oil leak on head gasket  put in tesco 15-40 diesel mineral oil in it as advised on here to be honest when its warm the oil seems pretty thin i put the new head gasket on dry with no sealant on or the pucks and o rings. with the front nuts which are next to the spark plugs loosening abit could get 1/2 a turn on them im abit worried about the ones you cant get to anyone got any advice or do you think its an engine out job
thanks

hairygit:
Hate to say it, but to do it properly is engine out time :( Get yourself another head gasket, as it may continue weeping even after torqueing up if it's been run for any amount of time. Bite the bullet and buy a genuine head gasket if it does need replacing, safest option to avoid future hassles ;D

K2-K6:
I'd go along with hairygit on this one. You already have your own suspicions about the status of the unseen studs so I can see only the logical path of a strip of the head to get it right.

As to the sealant use, I've always used blue hylomar on these (I know that is not entirely agreed with, so you have to make up your own mind) and always the absolute smallest amount needed to coat the surface so that it has the appearance of something like sellotape, i.e. absolutely no surplus that could be squeezed out. UKPete has recently used a spray version to get a very thin coat with good results.

I know it's generally avoided to want to remove the engine, but it is I think easier than most people remember and worth the time to get it leak free.

thanks for replies should have read the forum before i built up the engine on all the previous engines i have rebuilt i have always used hylomar i swear by it but never on a head gasket its the re torqueing i never took into account cos ive always retorqued the engines without even thinkin about it i just dont wanna scratch and mark anything after all the hard work ive put into it
