345 husky with big air leak where metal crank base meets plastic base,,,,
What a fukin pain,,,,,
Great info,, well its together, and I did note no bevel!! and the long bolts,,,,,Chit!!!Check here for pinched bearing seals between the cylinder and case. Earlier version (and many aftermarket) housings and risers didn't have this bevel to account for the seal being squeezed out not allowing good enough mating between surfaces even with sealant. Sealant eventually breaks down/separates and leaks like a sieve. The bevel creates an allowance for the seal to flatten a bit in that area. Just add the bevel before bolting it back together if necessary. Credit to TorR for bringing this to light some time ago. Another possibility is the wrong bolts (too long) being used to fasten the cylinder to the housing if someone has been messing with the saw before..., maybe with an aftermarket top end kit with supplied self tapping bolts.
'Course it could also just be a busted housing or cylinder base if you haven't taken it apart yet.

Unit seemed to bolt up fine,,,,time will tell.
I know the saw was fondled B4 me getting it, chink top end.
It seemed like the sealant failed in this area,, bubbled like a bugger there.
Some weird sealant,, almost like the fuel attacked it or lack of .
Its been resealed and will let it sit for a few days,, its a fun saw.
