Mile High Posted December 26, 2004 Share Posted December 26, 2004 Hey guys and gals, I have a car question for those of you who know what you're talking about. I started my truck (98 F150 4.2l) last nite and noticed a loud knocking sound. There is approx. 112,000 miles on it right now. I drove it and the more I accelerated the faster the tick or knock got. Later that day i added a quart of oil and the knock died down a little but still didn't stop it all together. I'm NOT driving it now and will probably wait until I can get it into the garage on monday or so. Any clue as to what this could be? If I could get some kind of opinions as to what this could be I would be grateful. Thank you and Merry Christmas! Link to comment Share on other sites More sharing options...

It happens when you have insufficient oil or too much sludge in the engine. The bottom of the engine doesn't get the lubrication or dispersal of heat required and that causes the rod bearing to go bad. I would hold off driving it as long as possible, though I've seen people go a couple of months with a pretty angry knock. One of my friends once had a problem that sounded EXACTLY like a rod knocking. It turned out that the crank pulley was loose and was smacking against the pully pin. Not likely but it has happened.

Mark VI Posted December 26, 2004 Share Posted December 26, 2004 Hope you didn't throw a rod . That's $2500 of work for either a rebuild or dropping in a new engine. If it sounds like something is clanging around as you accelerate, bad news. I've been there. Link to comment Share on other sites More sharing options...
todd Posted December 26, 2004 Share Posted December 26, 2004 112K miles! Dude, that's awesome! That's a good amount of milage for a truck, so chances are it could be something pretty bad. You may have to cut your losses and get a new truck. Count your blessings that the thing lasted as long as it did, because that's awesome. Link to comment Share on other sites More sharing options...
