4.0 renix engine issue:
go through oil, about a quart every half a tank, I changed rms and oil pan gasket, rocker cover leaks a bit but nothing to worry about. I do have some good blow by that I catch in a 20oz bottle and fill about 12oz every tank. at times there will be a rasping poping sound like fire crackers going off (enhanced being i have a snorkel), and I have crap for power, i manually shift the aw-4 in order to drive, as in if I put it in drive it does not take off, lacks power, drop in 1st and it takes right off.
So my thinking is I have bad rings and my head is toast, what you think?
