I guess I misinterpreted the service bulletin I didnt think it required lifters. I got the impression the aforementioned spacer was the fix. I dont know if I would put lifters in this vehicle. Depends on cost and complexity of the job.

One other thing to check is the Evaporative relay on the passenger side fenderwell. My 96 Grand Voyager does the same thing, then quits after a few minutes. It's easy to see, just look on the passenger side front fenderwell, by the upper motor mount. It's the small part with the vacuum lines running to it.

With the engine running (cold start) disconnect one of the vacuum lines & plug it. If the sound goes away, that's what you hear. This "clicking sound" is normal.

If the sound doesn't go away, it may be a follower on the camshaft. The 3.0 Liter Mitsubishi motor is known for low oil pressure at idle. 5-10 psi is normal for these engines at idle. I've run this van for almost 100K miles with a clatter from time to time. Only thing I've done to it is replace the water pump, timing belt, hoses (and water pipes under the intake) and belts.

I think a cam follower is my problem, the noise is pretty much constant until higher rpm. Probably not an easy fix Im guessing.

ATF as a solution. Very good. Oil patch hands, when they have problems with engines in the field, use Automatic Transmission Fluid as a way to clean sticky lifters. This was demonstrated to me 25 years ago and does provide a quick option to see if you can free up some hardware this way. I would think too much for too long could loosen too much sludge so one should be careful on older engines.

May I offer two other inexpensive solutions to other problems?

Gas treatments you can buy in the auto parts store is mostly, if not all, mineral spirits aka
paint thinner, Stoddard Solvent, Varsol etc. You can buy this "cheaply" in bulk at some gas stations or your home improvement store in the paint section. I managed airplanes years ago and Varsol was used to dry clean everything from oil on engines, landing gear, to cleaning the fuel injector nozzles. The nozzles are different on planes than cars. The nozzles would be taken out and soaked in mineral spirits which cleaned them right up from the green dye and gunk that would accumulate and affect the fuel/air mixture on a cylinder.

Buy a container of fuel additive and compare the smell with mineral spirits paint thinner. NOT turpentine!

Upper cylinder lubricant additives are typically just a few ounces of diesel fuel. I saw a small amount of diesel fuel being added to gasoline to try and free up sticky valves again, in the oil patch. Buy a container and smell it. Diesel fuel.

Well, I added a 1/2 qt of ATF to my oil (engine was only down a 1/2) tonight. Seemed to be a popular course of action, not to mention cheap. Im gonna run it a while and see what happens. I'll keep ya posted on the results.
