Re: White Smoke
from experience, it was the valve stem seals that created the white smoke upon initial start up.when i first bought the truck, i really didn't notice until i changed my oil to a 5w/30w sythetic.i replaced the valve stem seals(the intake and exhaust are different but replace them all), it had never smoked or lost any oil. this is very common. you can have this done withouttaking the heads off. i saw a thread on this sight that had some very good ideas for the back yarder. use rope to hold up the valves (stuff the cylinder with a nylon rope and the valve will not fall.) go to your local tool shop and they sell a tool to collapse the spring for safe removal.
i now suspect the previous owner used a higher weight oil to try to cure this problem and it didn't work so he sold the typhoon to me beacuse he thought he had worn rings but tried to hide it from me, there is no honestly among some people, his dishonest selling of the truck got the best of him because it only took me a half day and a few bucks to have a smokeless truck.
