Infamous 4.0 tick getting gradually worse, should I be worried?

[bobbywalter]

any additives to oil for cleaning should be changed within a few heat cycles. especially risoline.


when you knock shit loose you are changing chemistry and can turn the oil to the bearing murdering acidic side pretty quickly depending on the situation. even seafoam.


if you are not actively testing long term, changing regular oil 2500-3k and synthetic at 5 k is pretty standard.

if you have been testing from day one and running bypass filtration you would be shocked how long high end oil can last with proper bypass filtration. a highway vehicle can see 50 k intervals with just filter changes at every 5k with top up....

that costs more then changing it though.

Its been maybe a little over a week and Ive got maybe 100 miles on the rislone. Probably 10 heat cycles...most drives are errands where its still warm starting up to drive home.

Now you got me worried its been sitting too long, should I change it now?
I have oil, filter(s) etc...

Leave it in there till the ticking goes away or you have more miles on it. The concerns the others have about stuff being knock loose in the engine are legit, but that is on a very dirty engine where the oil has never been changed. I know it's hard to believe, but there people out there who never change their oil, or don't do it on a regular basis.

If you know the history of your engine, or have been in it and know it's fairly clean, don't worry about it. From the description of your driving habits, that might be a part of the problem. Short trips are hard on the engine, if you read the manual, short trips require more frequent oil changes. If you can change the way the truck is used for just a little while, and take it on some longer trips with the rislone in it, it might have a better chance to work if it's going to work at all. This is just a easy first step to try and solve the ticking.

When I'm using Rislone to quiet a gummy lifter, I'll usually see results within 30 minutes.

As I said in my first post in this thread, if the tick comes and goes, it's a probably a spinning component that's not concentric. With a 4.0 that's usually a pushrod, but the rockers wear to the bad pushrods and should be replaced as well...

I can do longer trips. Maybe I'll take it dirt bike riding this weekend....That's about a 100-250 mile trip depending where I go.

My short trips aren't stop and go for I do try to avoid traffic lit main streets....which is possible in my area of L.A. being near the Angeles crest national forest.

The tick has quieted down quite a bit, almost gone. I can still hear it during warm up though.

I got it with low miles from an old lady, its around 92k original miles now.

Put it to you this way, sometimes I change the oil just because I have oil and filter and need shelf space lol.

Ironically my brain thinks the short trips are better, she seems "tired" after long trips, kinda smells hot and greasy after if that makes sense...probably because longer trips mean taching out in 5th most of the way. Anyways its a good excuse to go riding.

Tick is just about gone. Only there faintly still during warm up. It doesn't come back until the next cold start.

these days most oils dont load up the colognes like they used too. heavier paraffins is nearly a non existant thing.

risoline can wipe out valve seals and will add noise from new damage depending on what you are starting with. i learned that the hard way. not because risoline is bad, but because it works. and depending on what built up already chemistry changes quickly

so that is a potential thing. but also provable. back in the shit oil days it was also necessary.



the acids and negative ph conditions that can form, really do happen, i ran it long term back when you needed too because the 2.9s sludged up and leaked heavily it is where my dislike for Pennzoil and Fram started in the 80s and early 90s. and the flanged exhaust of the cologne would coke the fawk out of the shitty oil along the base of the valve cover and overload the gasket causing leaks...bad leaks .

you can get lucky, or use it correctly.

i suggest caution. because it does its job very well.
