Hey guys,
I have a Peterbilt with a 3306 which has around 180,000 miles. Truck runs strong but it’s burning through a good amount of oil and blowing some smoke. It blows smoke when it’s idleing for a while and when you go to accelerate it blows out but clears up when your cruising. It also smoke on deceleration down steep hills. When I go to get back on it, it blows out a big puff of smoke. It always seems to clear up when I get it up to speed. I’m looking for advice on how to test it and figure out where is the problem. I’ve been told it could be the rings or the valve seals, but I can figure out how to setup and do a leak down test. I would think if it was the pistons it would have a loss of power but it seems strong to me. I’m new to that site but I appreciate any help I can fer
