pitbull4x4 Posted December 5, 2010 Share Posted December 5, 2010 Are the valves on a 2.5 adjustable? Mine are making a lot of nosie when I am driving it. You can feel the back ones on the valve cover when it is idling. Can not fine anything in the Haynes repair manual. Quote Link to comment Share on other sites More sharing options...
jimoshel Posted December 5, 2010 Share Posted December 5, 2010 2.5 valves-lifters are not adjustable. First try changing the oil. If that doesn't do it try changing the oil weight. If that doesn't do it get new lifters. Sometimes I find the noisy lifter, rotate the engine until that lifter is on the high part of the cam lobe, and then smack it a good un with a BFH. That only works if the lifters are sticking. Quote Link to comment Share on other sites More sharing options...
1987Comanche Posted December 6, 2010 Share Posted December 6, 2010 You can replace lifters in the 2.5 without pulling the head :). Don't know why they didn't make provisions for that on the 4.0 but oh well. Quote Link to comment Share on other sites More sharing options...
