I started to think about my cars and my friends cars, both finished and under construction and every one has fuel injection or will have. I'm talking about a wide range of engines. 59 corvette with ls7, 55 chevy , 49 mercury, zo6 corvette, twin turbo dune buggy, both my cobras, my sons 76 cj7 jeep and you could go on and on. All have check engine light and plug in port to check codes. Also with the exception of the inline 6 in the cj7 jeep of my son, none of the others use
oil . The cj7 has a stroked crank and I suspect the pistons are the problem, uses a quart of
oil about 2000 miles. The pistons were custom made 20 years ago or so, 8 sets were ordered at the time to get price break, and these were the last set used in this engine. Not happy and not except-able in this day and age.
