stuck valve?

Thanks for taking a look.

I have a '94TJ 4.0L. Just recently the engine started making a knocking noise. The noise starts when the engine is cold and will last for about 3-5 mins before it quits, then the engine sounds normal. I've been told that it may be a sticking valve. The valves have always sounded loud (I've owned it for 6 years)I tried to take it and get an oil change, but the local "Jiffy Place" said they won't touch it with noisey valves. What can I do?

Thanks again for any advice...

Dude, if you know what the valves sound like, then you should be able to change your own oil, it takes 5 minutes if your good, and is actually kinda fun. If they are still loud take off the valve cover, and see what you find.

PS there is no such thing a 94 TJ. TJ's are 97+ wranglers. If your jeep is a wrangler, you've got a YJ. Just to let ya know.

heh.. there are a few solutions you can try.. Anytime my dad and a few other guys have had noisy valves/lifters etc.. they've added some ATF to their oil before they change it.. they run it a bit and the ATF foams and cleans the valves.. you can always get a can of motor flush also and do the same thing.. after you've done this i suggest mobil 1 Drive Clean blend.. I've also had good luck with Z-max additive in cleaning deposits..
