valve settings jeep 2.5, 1997

I have a jeep wrangler 2.5 l. 1997. The valves are very loud. You should be adjusted but I do not know how. Please if someone can give information to adjust the valves.

They adjust themselves hydraulically. You cant adjust them but you can replace the lifters if they are going bad.

If someone had the lifters out and didn't get them set right on the original tolerance then it's possible they are not working right. They of course don't adjust like solid lifters . I've done it years ago one an Chevy V8 but I couldn't tell you now exactly how to do it. If you can get a repair manual it will tell you how to do the original set up. Once they are set in that range then there is no more adjusting required. Making a lot or racket of course isn't normal. Good chance you may need new lifters if so then you can learn how to make the original set up adjustment

This above after I fixed it. lifters and cam must be replaced as a set. If the old ones were taken out and not put back in right hole they will eat the cam and them selves up.
There is no adjust ment for them. Engine oil pumps them up.

but you may have a bigger issue.
NOISY VALVES/LIFTERS
1. High or low oil level in crankcase 1. Check for correct oil level. Adjust oil level by draining or adding as needed
2. Thin or diluted oil 2. Change oil
3. Low oil pressure 3. Check engine oil level. If ok,
Perform oil pressure test. Hook a manual pressure gauge to fitting on block.
4. Dirt in tappets/lash adjusters 4. Clean/replace hydraulic
tappets/lash adjusters
5. Bent push rod(s) 5. Install new push rods
6. Worn rocker arms 6. Inspect oil supply to rocker arms
and replace worn arms as needed
7. Worn tappets/lash adjusters 7. Install new hydraulic tappets/lash adjusters
8. Worn valve guides 8. Inspect all valve guides and
replace as necessary
9. Excessive runout of valve seats or valve faces 9. Grind valves and seats
