I have a 2000 expedition 5.4 liter xlt 4wd w/ 130k miles. When I start up it knocks real bad for about 10-15 seconds then goes away, then it will start "clicking" under slight acceleration. I dont know if its an oiling problem or something internal that i cant fix.
I'm also having issues getting to the spark plugs in the rear of then engine they seem so far under the Firewall that the engine needs to be dropped but that seems excessive to change the Plugs. Obviuosly they are coil over plugs
