Wierd One...Need Help with Knock
Ok, I have an 89 F-150 4x4 with a 5.0 about 115k miles that has developed a knock. This knock sounds like it is deep in the engine, but is intermittent. Plus, when you take the Serp belt off, the knock goes away completely. I have replaced the alt, belt tensioner and pulley but knock is still there. Any ideas???
