briggs vanguard 20hp v twin crank case bolts

[jez456]

Hi stripped down the old engine to replace various gaskets and seals to get rid of the leaks but noticed one of the crankcase bolts ( if the engine is on its back pistons in the air pto side to you 3rd bolt from the bottom right hand side) is very oily. obviously this must be shared by an oil way? but on reassembly do we just throw the bolt back it and it magically seals or am i missing something embarrassingly obvious!

thanks in advance

That hole with the recessed area for an O ring is the oil passage that in combination with the sump gasket should seal everything up.

hi yep i have that hole which will be getting a new o ring but its the bolt hole above that which passes through the locating peg i am talking about, came out very oily just worried after spending a fortune fixing leaks i will get a new one there on reassembly!
