Stihl 064 Leak Testing??

[99busa]

I just did a quickie leak test on my junkyard dog 064 and it has multiple leaks, however the biggest one appears to be leaking from the bar oil pump output hose. Does this make sense to anyone?? I thought the oil tank, pump, vent and output hose nipple were all a self contained loop?? I guess its time for the 5 gallon bucket of water per Lakeside to track the smaller leaks down. Any ideas anyone?? Thanks

If you're pressure testing the CC and are getting leaks form the oiler hose, then you have a case gasket leak and will have to split the case halves.

I'd hope so, otherwise could be a crack.

The oil tank side case screw was loose, i'm going to replace both crank seals, as the flywheel side is leaking badly.

Thanks for the ideas
