hey guys i got a 1988 jeep Cherokee limited inline 6 4.0. and i need to adjust my valves how would i adjust my valves because i have loose valve and needs to be adjust but dont know how. could you guys give me some pointer on how to adjust them because my master mechanic buddy is gonna be helping me and idk how and i dont got specs on what the adjustments need to be such as torque and how tight they need to be thank you
The injectors are fairly loud on the 4.0 and can make a ticking sound. The stock exhaust manifold is also prone to cracking and makes a ticking sound as well when it does. I'd start on checking those first.
How long have you had it? Is the oil full and when is the last time it was changed? The 4.0 takes 6 qts of oil. Have you ever cleaned the fuel system and motor with seafoam or something similar? Could be sticking lifters.
On an unrelated note you have an XJ Cherokee, not a full size.
im do oil change tuesday its full on oil im put some sea foam in that stuff always cleans well so ima try it thanks man ima put full can of sea foam in oil and full thing in gas and whats diffrent on size what you said last
