Engine Mechanical problem
2002 Jeep Wrangler 6 cyl Four Wheel Drive Automatic 95000 miles
I have a 2002 Jeep Wrangler with an inline 6 cylinder engine. It started to make a tapping noise from the lifters. It's really noisy when I first start it up and quiets down after 15 minutes or so. I have used the engine flush which seemed to help a little. I also tried a thicker motor oil and that seemed to help but these two options didn't fix the problem. I am thinking it's a sticking lifter. I removed each rocker arm and pushed down on the push rods and the lifters seemed to be strong as I couldn't budge them.
Should I try more engine flush, I've done this three times now, or install a higher volume oil pump? My last option would be replacing the lifters and the manual says I have to pull the head off to remove them. Is there no way to remove them with the head still on?
have the same problem?
