Id go with valve seals as it loads up while sitting and dumps smoke upon take off then clears up mostly.Iknow with gassers if you go down a long hill (and dont hit the throttle at all) with the backpressure holding you back (od off) then at the bottom when you hit the throttle watch the exhaust if its a crop duster then clears up for the most part theres a problem with the oil control rings and ive saw where theres good compression numbers but burned oil. Dont know if this is true on a diesel but I cant see why not. Did they hone the cylinders right or where the cylinders just in spec but should have been bored but they skipped that step to save funds, and was it a reputable shop or a shade tree backyarder that did the work?
