I assume before u started it up after sitting for 1.5 years u changed the oil and filter? If u didnt,all the condensation from the last 18 months has settled in ur oil which causes the milkey look.If ur head gasket has blown,oil will look milkey as well,plus u will have an oily sheen to ur antifreeze and exhaust will smell sweetish like antifreeze.Pull ur plugs and see if theu are oiled up or are burning clean.My guess is dried out valve seals.Change oil,use a Maz oil filter change the air filter element and run the truck for awhile,seals may lube up and be ok,but if not they are pretty easy to change.BJ
