A cure for clicky lifters?

Does anyone know of any tricks to curing clicky lifters? Not a permanent fix, just one to last a few months until I find a suitable vehicle to overhaul the Jeep.

I think it's only one that is clicking, not 100% positive, only clicks under load.

Trans fluid will also help. Could be a collapsed lifter caused by debris in the plunger.

i can vouch for the Marvel Mystery oil, although I used it on older SBC's. Its basically moly disulphide in an oil base (as opposed to the usual grease)

Drain oil. Add 1 qt Lucas. Fill with Rotella T 15W40. Enjoy a quiet engine.

418 miles on 19 gallons of gas. Can't beat the BBD !

^^^^ This. I switched to rotella a while back and you should have *seen* the crap that came out of the engine the first few times I changed it. Looked like road tar.

I will second the quart of ATF, right before the last oil change I added a quart of ATF and drove it for a few hundred miles then did an oil and filter change with IIRC Quaker State High Mileage 10-40.
Man was that oil ugly when it came out and it had only been in there for 4k miles, looked like tar alright.

Now I no longer have any clicking lifters.

I think I will give the ATF a shot, since it's so dirt cheap. I'm hoping the issue goes away for a while.

Rotella quieted mine down, but it wasn't an instant fix. Took some time.

What I did was put 1/2 a bottle of Seafoam in, drove it about 30 miles. Then I changed the oil to Rotella. Drove about 100 miles and then changed the filter and topped it off. Drove it another 2000 or so and then repeated the process.

Since then I've just been changing every 3000, Rotella 10w40 in the winter and 15x40 in the summer.

Sometimes I get a little clicking when idling, but if I give it a little gas, it goes away.

Here is one for you. and I did it. 10,000 miles ago and it runs like a champ. first off I tried Seafoam and other products with no good results. My lifter was stuck and noisy. I drained my Oil. to about one liter of Oil. added 4 liters of Varsol, and fired up the motor. I let it idle for about 5 min and then drained it, added new oil and filter ran it for about 20 min then drained it as well and replaced the oil and filter. It has ran better then ever. no noise nothing. It is hard on the seals but mine were already leaking and due to be replaced. I did it, was told to do it by old timers who did this back in the day. I had nothing to lose. I was looking for an excuse to rip the motor down and stroke it. Well not yet, I bought time. Did a compression test. all good. As long as you don't put it under load and go for a scenic drive you wont hurt the motor Varsol has lubricating properties.

HOLY COW! I can't believe what I just read. I posted the ATF trick several months ago and got nothing but hell from everyone for the suggestion. I'm glad you all came around and discovered that it does work and it's cheaper and better than the snake oil additives.

Yeah they weren't very charitable last time this came up. I am old school and was taught this back in the late 60's. I guess new ideas and new products have some thinking different.

I had nothing to lose and tried everything else. I knew my seals needed to be replaced and the plans was to stroke the motor. I did not even read it on the Internet. One time deal. Now I keep the oil changes on a schedule. Believe me I thought this Mechanic was out of his mind when he told me this. I started to ask more about it and got the same answer but with Diesel as well. respectfully , I never posted this flush in the beginning because I did not know what to expect. I waited till I got miles on the motor and to see if the lifter noise came back ,or if I did damage something else. Now I will post my results. Or today is the day I fire her up and the motor blows up.

The problem with the ATF trick is the tolerances of the newer engines. ATF has less lubricity and more "detergents" in it than engine oil, both have the ability to 'wash' out the bearings in the newer engines due to the tighter tolerances. Less room between the bearing and the (insert rotating assembly component here) the higher chance you have of destoying something with a lower lubricity product.

Back in the day, I remember running 2 quarts of ATF in a motor than got some water in it. Never had any issues. I also remember old timers pouring a cup of kerosene into the the oil just before changing it. Using kerosene and Marvel Mystery Oil to loosen up a rusted tractor engine. Poured it right in the spark plug bung, let it sit over night, cranked it over the next morning and it fired up with some fresh gas.couldn't do anything like that nowadays

What I've heard is STRONGLY against that. It's a popular folk remedy but ATF will quickly oxidize and deterioriate under engine temperatures, and cause all sorts of issues.

If you're going to use an additive, use something formulated for the purpose.

One more thing, if it ticks louder under load, it's almost certainly not a lifter. A lifter does not 'feel' the load (unlike a bearing) because it only works against the valve spring.
