Ford 6 Cylinder
Why does my 89 Ford Ranger (2.9 V6) engine tap (push rods/lifters) for a long time then go away and come back?
What will cause the tapping of a push rod/lifter to sound awfully loud for about 30 mins and the go away and back to normal then repeat again? On an 89 Ford Ranger 2.9 V6? I've been told that it's the lifters which I am going to change on that particular tapping pushrod. NOTE: I did take off the valve covers and looked at the pushrods to see anything unusual with the engine running which I did notitce that the one that was tapping was not totaly wet with oil like the others. Thanks for any help you can provide.

- they need adjusting . get a repair manual at the store and it will tell you how to adjust them . it might be that you might have to replace your oil pump too .that is a real problem with these german engines. here is a website: http://www.carsurvey.org/viewcomments_review_21811.html
- Why not just buy a whole new set of lifters and then not have to worry with it? It won't take that much more time to replace them all. It sounds like you have a collasped lifter or sticking lifter. When it heats up, it may free up for a while or else the parts expand and takes up the slack in the lifters Good luck either way you go.
- It sounds like the lifter is going bad or the oil pressure is low. The lifer pumps oil throught the push rod to lube the rockers arm and valve.
- The lifters and cam wear in at a patern and should not be mixed as this will cause a hi wear situation. The lifters should have a convex foot (bottom) if not then replace the cam and lifters as a set. The tic as you discribe sounds like a bent push rod. as the rod rotates into the angle that coduses the tic then out of this angle . check the rod against a flat surfice rolling it should show the bend or worpage.
- ADJUST THE VALVES AND THAT SHOULD TAKE CARE OF YOUR PROBLEMS.
