Husqvarna 365 Special Air Leak to Oil Tank?!

[ChillyB]

So I bought this project saw and knew it needed work. I say that only to explain why I didn't leak test it before pulling the top end. I had already counted on changing the oil seals, and had no expectations except this saw was all there and might be made to run with work.

Tonight I figured to rinse the bottom end with ATF since there was some carbon on the crank counterweights. What do I see but red ATF running out the hole for the oil pump hose. I guess I'm splitting this case after all.

Anyone ever experience a leak between the oil tank and crankcase?

Gasket failure and it can happen- but how often do gaskets really fail?
However, if the saw drops a bearing and part thereof does a loop around the crankcase and gets caught at 12 thou RPM between crank lobe and a thin bit of magnesium case- then hell yes, there will be a leak between.
