Thanks for your ideas. A little more background . Truck has been running for a little over a year now . After i pulled it out of the bush it proved to be an easy start. Got it up and running easily and road worthy. Everything works on the truck down to the vac wipers and clock. After driving it for about 1500 miles the water pump needed replacing. Shortly after I cracked the bottom of #3 piston off. Not too much damage and it gave me a chance to inspect. 60000 original miles on the truck. The engine looks as it seen a freshening up recently although it would have been some 30 yrs ago. Got it back together broke in and it stopped using oil after first oil change. Now i have been driving it harder and is using oil at higher rpms. Pistons were all out oil rings set. But you know how that goes... They will more than likely just rotate where they want to go anyway after a few miles. It could be as simple as a set lined up by fluke . Pushing oil out at higher rpm because more oil being splashed around. Note... Since I have been running it harder I have been keeping the oil line at just over full by a small 1/4". I have been wanting to spin it harder to 3000 or just above but a little nervous. I don't want the dippers to run out of oil at 3000 rpm so the higher level of oil should ensure contact with the dippers. Could I be splashing so much oil that i'm pushing it past the rings ? Would I not need an extra gallon or 2 of oil in the pan before I would see anything detrimental ? Thanks.
