Stiction eliminator?

[rusty ol ranger]

Yeah i know no mechanic in a can.

But has anyone tried this to cure lifter noise? I realize it probably wouldnt work at all but would it hurt anything to try?

If i lose 20 bucks then so be it.

I though the 2.9 lifer noise was caused by low oil pressure?

I though somebody did a writeup explaining how to modify the the oil passages to increase oil flow to the lifters and eliminate the lifter tick on the 2.9s.

I wouldn't imagine that that would help, if this is the case.

I understood it as the passages that feed the rockershaft being gunked up. Or worn cam bearings.

I think mine is the former as my lifters tick after a long ride at speed...but then quiet down pretty quick once the RPMs drop.

I dont have any other noises to think its a pump/pickup issue. I was just curious if it would do more damage

I've had a couple 4.0s that had horrible lifter noise. One would just sit there and tick tick tick tick.... quiet.... tick tick tick tick.... quiet. All day long. I dumped about a quart of diesel fuel into the oil and let it sit and idle for about half an hour and the noise was 95% better. Changed the oil and it still ticked on occasion but not nearly as bad as it did.

Long term I'm not sure if doing that would be a good idea, but it was a $200 truck so I very little to lose by trying it.

I just think its odd how mine ticks. Its definantly top end. If i run it 55-60 for 30+ mi itll rap pretty decent. Then i get in town cruiseing at 30 itll go away in a mile or 2 and stay shut up till the next long run.

Which is why i think its more some sort of starvation then actual wear. More a volume issue then pressure.

I thought about diesel fuel too. Maybe ill try that instead. Ive dealt with it for years its not a big deal just wanna try some stuff to experement. Just dont wanna dick it up more.

What oils weight do you run?

10w40 max life synthetic blend. Usually with lucas. I didnt run lucas last change and didnt notice a difference.

It used to tick badly when i first got it going. Thats why i started the lucas which seemed to help. But now its quieter without lucas then it used to be with. Seems like every oil change it was getting better till the last few. It hasnt gotten any worse, or better. Thats another reason i was thinking gunk over pressure

I wonder if running a thinner oil would allow for a better oil flow at higher rpm.

Maybe 10w30? I just bought a jug of 10w40 to change it. I always ran 10w40 in my other older stuff. I dont know.

Can't hurt

 

[rusty ol ranger]

Can't hurt

Lol. Im gonna try the hotshots for the helluva it then maybe next time try the thinner oil. Its not my DD no more so im free to experiment a bit more.

From the website Stiction Eliminator for Gas & Diesel Engines | Hot Shot's (hotshotsecret.com)

"Stiction Eliminator is an oil treatment for gasoline and diesel engines that is engineered to remove stiction, the sludge and varnish created from burnt oil, while also lubricating the system to improve performance and reduce engine wear."

Unless you have sludge and varnish from burnt oil, a waste of money IMO.

What else would be possibly plugging up the rockshaft passages though?

It was 16 bucks at napa. Im gonna give it a dose and report results

we run atf through the engine to clean stuff like that out. our you can also use diesel but i have not tried that. replace one quart with atf and a bunch of junk will come out though

When I had my 89 STX with the 2.9L engine, I ran 20W-50 Valvoline synthetic oil from the first oil change when new. I only had a lifter tick one time for about 2 minutes when driving to lunch one day. It just suddenly came and went and never came back again. It had almost 200K miles on it when I sold it.

I also had an exhaust tick a few times. The right exhaust manifold would warp from the heat a little resulting in a light tick. I milled it flat, and it would be fine for a while. I tried using an exhaust manifold gasket but that didn't last as long as milling and installing without a gasket. The last time I milled the manifold I decided to try running it without the heat shield. That solved the warping of the manifold and never had an exhaust tick again.

The only time the higher weight oil had any effect on the engine was when I went to the mountains in the winter. It would turn over slow with a cold start, but it would always start.
