intermittent top end knock?
My 90 ranger xlt 4x4 5spd 2.9 sat for some time, apart. I bought it as a jigsaw. 5 weeks later runs good, excelerates, good power. But every other time I run it knocks like its coming apart. Other than the sound it seems to be running good. No overheat. Good oil pressure.im gonna pull valve cover later, could it be plugged oil passage from sitting? Fix w compressed air?? Could I get so lucky? Just wondering if I'm On the right path.cuz it still runs super. Knocking or not. Please advise. And thanx,
