- 1998 XLT 5.0L AWD
I've read through a good 20 posts about engine knocks but non of them seem to replicate mine. 115,x.. miles on a 1998 5.0 XLT AWD. I aquired the truck @ 98,000 so I don't know it's history before me but I've had oil changed w/ 10 30 every 3000 since. Anyway..engine has a very faint knock at idle. Doesn't get louder upon acceleration or just revving the engine. Only at idle. Oil is clean, runs like new, drives perfect. I know I've heard "this is normal" for the 5.0, etc. My 4.6 in the expedition used to knock at start up but went away when it warmed up. This is always there but never gets louder..idea or two? Truck cost me $300 bucks so I'm not interested in dumping a ton of money into her. It's also my work truck so it's driven M-F but I have 2 other cars.
