Having problems with your 1998 Jeep Grand Cherokee ?
Lifter knocking like crazy all of a sudden
\015 I have a 6 cylinder jeep grand cherokee. The Crankshaft Sensor went out. I paid a mechanic to fix it. Two miles from the mechanic the #6 lifter started knocking like crazy. The mechanic said that from trying to start the car when the sensor was out I collapsed the hydraulic lifter and to put some tansmission fluid in the oil, run it 150 miles, and do an oil change. It hasn't helped and it's getting really bad. I asked what it would take to fix it. He looked in two manuals. One said that you could get to the problem only by pulling the head-the other said through the valve cover. What would you suggest? And how big a problem is it? Any other suggestions would help immensely. I'm on a tight budget and it's my only transportation. Thank you very much for any help you can give me!!!\015\012Sincerely,\015\012Jonnie Allison\015
I'm not positive but this may be worth a try,pull the valve cover and find the loose rocker and push rod,pull the rocker off,note how many turns it takes to remove the nut so you can reinstall with the same number of turns,then push down on the pushrod,it should give if there is air built up in the lifter,this should push all the air out and allow it to be pumped up with oil when you restart the motor.Like I said I'm not sure if this will fix the problem but may be worth a try.Please give a rating only if it helps.
