Advice needed 4.0l

Have a 98 ZJ, 170,000 miles with noisy lifters. Are they adjustable? Any tips or recommendations? Thanks.

I have had three I6 motors with noisy lifters when the engine is cold. I, personally, think that's the way that motor runs.

I would say that if the noise goes away on acceleration, you're probably good.

Also, something that helped me was to use Castrol High Mileage 20W-50. It's heavier than what you normally use, but it helps the oil stick a bit better. Also, I do believe what they say about it reconditioning seals. While it won't fix your rear main seal drip, it will probably slow it down.

Thanks to Tahoe

Thanks for the reply. Did some more searching into the topic and found info on Seafoam and other lubricants.

If mine didnt sound like a diesel when it is warming up, I'd think something was wrong with it. My 95 and this 97 both have the same sound and I bought them both brand new.

I add a quart of Lucas when I change oil and it helps.
