What do I need to do for this upcoming winter? Right now if it gets below 50 it takes a little longer to start and blows lots of white smoke for about 30 secnods or less. The bad part is that I never knew how the truck ran when it was stock, so I am jumping in all new Territory with lot of stuff done. Now I have my intake heater removed, should I put that back in, should I go with lighter weight oil, shouldinsulate my fass filters, should I get a winter front for my grill, and anything else I need to know.
