I think I got 603-971 syndrome ! It uses approx 1 qt per 500 miles, 1 tea spoon of oil at turbo boot! intake is very wet ! No oil comes from breather pipe, looks like some is coming out of #1 exhaust manifold ! as well as the front half of block is wet, runs real well no smoke, but a small amount after its been shut down fo ahour or so ,than clears up! What next?
#1 a rebuilt 603.971
#2 a rebuilt 3.0 lit with some perf mods.
#3 606 into this puppy ?
Who am I kidding ? I want #3 but I cant brake the bank ! thanks J
