Hi Scotty, 2002 Ford Ranger 3.0 knocking from bottom of engine at very cold startup (- 17 on Tuesday). Is this piston slap or just a cold engine starting? Oil pressure is fine. No noise after a couple of minutes.

it should not knock, period. And bottom of the engine already has plenty of oil in it, the top would make noise on cold start ups. I assume engine is on its way out
