Yamaha ME421 - help!

[osprey24]

I have removed my engine to do a light overhaul and re paint.

Im in need of a rocker cover gasket - anyone got part numbers or where to get one from?

The crank carrier is that a gasket or a “make your own gasket” ?

Same with the sump is it a make your own style ?

Rocker gasket is Toyota landcruiser hdj80 available from toyota or most car parts dealers or online roughtrax or milners 4x4
Sump gasket is silicone but if its leaking its more likely the sump rotten its quite common. not sure what you mean by crank carrier?

Thanks for the reply.

The sump isn’t leaking, it’s the block of metal above the sump, I think I have a small oil leak there on the gasket.

Got the sump then above that there’s like a block of around 4” deep is that a gasket?

The block your talking about is the ladder frame which carries the main bearings its the bottom of the engine. I'll guess its leaking behind the waterpump? If it is its usually a hole rotted through the casting where water has been spraying from the seawater pump. The ladder frame is just siliconed on too & anything needed doing with it is fairly major surgery
