| The base gasket is more of a shim to set the squish than a gasket.
The oil leak is likely to be the o-ring on the rear rhs at the base of the cylinder.
When you reassemble the cylinder, coat the base gasket in threebond (rtv sealant) and grease the o-ring well. You can clean the old base gasket up and re-use.
If the o-ring is fitted dry, as it is at the factory, it goes hard and ceases to seal properly...............hence your leak.
Not a difficult job. The hardest bit is getting the circlip back in the piston!! |
