just drilled and tapted zt head to fit s2 manifold,the studs that go into the oil return what should i put them in with (eg chemical metal,gasket sealer.etc) please help

 

a smear of oil resistant gasket sealer should be fine - presuming they are the torx-headed studs with the raised ring round the middle, the sealer and a nice snug nip up against the ring should see it ok - no problems with ours doing that.

 

thanks il get that done tonight thanks for your help.tommy
