Cold Crankcase Ventilation (CCV) and engine damage

[FrozenOrange]

I'm thinking my l3901hst may be a victim of this. At 104 hours my rear main seal is leaking oil. i have had my tractor 9months and 5 of those months have been in what those in the lower 48 considered cold weather.
Dealer said bring it in "sounds like a warranty fix" so I'm hauling it in Monday. Should be interesting to see if a frozen PCV system is the culprit or just a bad seal. I'll mention the CCV concern when I drop it off. I sure hope this is something I won't be fighting every winter.
Spring is coming. Oh wait it's only March. Two more months of snow.

My dealer contacted me and updated my L3901 HST about 1 month ago. It takes about 4 hours and consists of a heated tube for the CCV and a new alternator to handle the additional electrical load.

4 hours seems excessive to install the kit. What did the dealer itemize on your invoice?

When you live in Alaska everything freezes unless it is protected by a heat source. Did your dealer charge you for the recall upgrade? If so, I would be having a discussion with the Kubota rep or corporate.
