One was a product call Yammabond in the US a bike sealant..
( my mate Tony has a 912 out there he does alot of time trials and the car is driven hard.. I looked under it and it is leak free...
Another is Pete at Funkenblizt who uses a Mazda sealant £18 a tube it swears by it.. and his motors don't leak oil..
Any one have any idea's
I don't mind spending £20 a tube if it helps reduce oil leaks heck I would spend a £100
