just noisy lifters.. go to a higher weight oil and it should go away somewhat.. running a motor flushing solvent before your oil change will help fix this somewhat by cleaning the lifters. If you're using 5w30, try 10w30, if 10w30, try 10w40 or even 10w50. If it doesnt fix the problem, you may just have to live with it, or you can try 20w50 as a last resort. It's not anything that's gonna blow up your engine, just your engine telling you that it's getting time for a rebuild sometime down the line. I've got a 92 explorer that does it all the time. goes away when it warms up..
Awwwwwwwwwwww... So he wants to go OFF-ROAD does he????
