My 1992 5.7L uses a quart every 60 miles and doesn’t leak or smoke. I do see a little smoke when I take the oil filler cap off but it’s not much, and there’s no smoke out the tailpipe. I don’t think it’s leaking only on the road, because I’ve tried stopping along the road and checking for drops, but there’s none. The compression is around 120-125, pretty low, but if it was burning a quart every sixty miles by the rings or valve guides, wouldn’t it be smoking like a chimney? Well thanks, any and all suggestions would be greatly appreciated because I’m at my wits end
