Maybe I was unclear. I meant valves. I think they can be adjusted, but I could be wrong...I'm certainly no mechanic. Thanks for your help.

Well, adjusting the rockers on a vehicle with adjustable rockers, is adjusting the valves, so you were correct!

Engines with with hydraulic lifters are designed to eliminate the need for this adjustment.

Gotcha. Thanks!

No problem!

Have you decided which way (ATF or MMO) that you're going to go?

I'm thinking that the return of the tick in mine is caused by the depletion of the additives in the oil & MMO in the past 2800 miles. That's why I want to repeat it exactly as before, so I can see if it's really helping.

After talking to my engineer buddy, I'm leaning toward the ATF. I'll be sure to post the results.

Hope it works again. I'd be interested to know if it does. Thanks!

Yeah, like I said, I'm running regular Castrol 10w40 synthetic (not high mileage-specific) and it runs fine. The ticking got better for the first few months that it was in there, and I'm definitely not burning oil, so I think the rings are sealing just fine.

On another note, I discovered my valve cover gasket was leaking much faster that I originally thought, so I am currently running a quart or so low (ALWAYS good for tapping lifters

) SO I'll be replacing both the gasket and the lost quart later today. I'm sure this will help somewhat, but I'll definitely be tossing some ATF in there about a week before the next oil change, just to see what happens.

firefighterjeep: You're source says it's ok to leave it in there "a few hundred miles" thats different then what I've heard, but I haven't done a lot of digging into it yet...

I'll have to ask him again to make sure I heard him right, but I'm pretty sure he said it's ok to run it up to 200 miles. Thanks for pointing it out.

I am running Rislone in mine right now, only 100 miles since I put it in and no difference. This noise is driving me NUTS

! Any harm in adding a little extra oil? My engine only has 48k on it, really shouldn't be having these problems. Also, what kind of other problems can this cause? It sounds pretty nasty at times but then goes away for a minute or two and comes back. It is usually worse at idle.....

On my '91 Yj with 148,000 miles, I now have 5,000 miles on 6 quarts of Castrol GTX 10W-30 High Mileage oil, a Fram PH8A filter, and 1 quart of Marvel Mystery oil.

My ticking is 100% gone. I am not usually fond of "Snake Oil" type remedies, but this combo worked for me.

Marvel Mystery Oil fixed my lifter tick several years ago and it has not returned. I put a quart in with the old oil 200 miles before I changed it. I then changed the oil with no more Marvel mystery oil and the tick is gone. It is only about $4 -$5 a quart at Walmart.

I ran a quart of MMO for the entire 5,000 mile life of the oil, with no issues. Worked for me.

I guess I can try that, it is basically just a detergent no?

mean max: did you also put the 2 ounces in the gas tank with every-other fill up? i have the lifter demon as well, and i am concluding that this may be a good antidote.

No, I didn't. I had intended to do that, but only to help clean the injectors out. I wouldn't think that adding MMO to the fuel system would be of significant help to the lifters, that's why I put it in the oil.

If you have justy done a fresh oil change recently, I would try spinning the oil filter off & replacing it with the larger filter (PH8A or comparable) and topping up your oil with the MMO.
