On a few of my older cars that were pre emissions with solid lifters I used to add a zinc additive to my oil to help keep them from wearing down and beating the crap out of the valve ends.
Was wondering if on a deleted truck if this would help the 6.4 from eating up rockers as quickly? Or are the pressures to great?

The bold^^ is what I would worry about in the 6.4. They are hydraulic and I don't know how those would hold up with the zinc. Plus nowadays engines are built much better with higher standards and closer tolerances. Also Oil has come a long way since those days. If I remember right the zinc'c primary job was to act in absence of the lead when un-leaded hit the streets.
The lifters are just a wear item in the 6.4. The leverage they are required to put out is what wears the tips out. That said Oil quality and OCI play the biggest role. I run a 5w40 Full synthetic with Archoil every 5k. The added lubricity from the archoil should help the rockers.
As far as the lead replacement....all I remember is the old timer I was working for was saying that the older vehicles designed to run on leaded gas lost/weren't designed to run un-leaded. Something about the leaded fuel burns and leaves behind something that then gets transferred into the oil. With out the lead there were having premature engine failure's. I am only 30yrs old so this is all hear say and I might be passing BS along. All I know is he grew up with those and working on them and that's how it was explained to me. I aso remember hearing that the zinc additive helps with engine break in, but that it shouldn't be run all the time.
Oh I remember from my old Z car that it needed leaded fuel because the valve seats where to soft for unleaded fuel. I knew I was forgetting something. And i was also told by an old machinist to run zinc on break in and it wouldn't hurt to run with it all the time. but it will burn up cats and such.
It is funny now that I think about all the people that come into the shop and use that line. Its like they think some products are absolute and not effected by technology. I don't know why that is.
OP, I don't know if the zinc would help at all, I will say to look into the nano borates and the technology behind it. It the "secret" ingredient in the archoil or rev-x. It cuts the friction down exponentially and I would think that will help with the rockers. I a running it now like I said and will see what the rockers look like when I need to stud this one.
Zinc clings... It won't abandon hard parts... It allows oil to cling to hard parts when they sit long periods. Great for classic cars that aren't moved much, and marine engines that can collect condensation easier than others.
Zinc will destroy a catalytic converter in short order... There is a chemical reaction between zinc and the catalysts, just like there is between diesel and anything galvanized.
This doesn't answer the OP's question on if it would be ok/beneficial to run in a 6.0. but does explain zincs role better. Kinda curious on your take Drew.
Wonder why Rev=x and Archoil don't publish some of that with their products as advertisement. A 67% reduction when used with a 15w40 oil is why I have been an avid user of the 9100 even after I got rid of my 6.0.
Industrial additives come in 55 gallon drums. It is my contention that Rev-x and maybe Archoil are merely repackaged or differently packaged forms of these (well known in various industries ) additives. I may be wrong:tard:
If you see a difference, imaging what a 4000 HP ship engine sees.
Archoil is actually an amazing company. The greases and fuel additives I stock because of the quality. The company its self is on the forefront of developing better oil grease and other additives.
Patriot- reducing friction (lubricity) is one thing.. protection is another... yet another is suspension of contaminants, especially acidic contaminants which is a byproduct of combustion.. then, striking a balance for uses/purposes/needs... This some cra cra shizen, yo.. and the reason there are tons of oils on the market.
Toren: he's right.. it's now zddp... And if you're asking me if it's okay, I think it is so long as it isn't so much that it counters the purposes of the other stuff in that oil... I don't know where that cut off is, so I don't mess with it and instead hope the white coats kept their end of the bargain, ya know? That said, zddp clings- both in use and while the engine just sits there... Clinging is good, to a point, but bad if it won't let go- meaning the layer closest to the part doesn't exchange in the oil flow... You've seen the remnents of this I bet... We called it Cajun crust round here.. it's that black crap that is so stuck to a metal it won't come off. Lifter retainers are notorious for this. So are valve stems and valve backs... So.. too much cling is a bad thing, too.
If my 6.4 Sat around a lot? Damn right I'd load the oil up with it. It doesn't, though, which means my primary hopes are for good lubricity and good detergent (ash suspension)... The boron holds promise if they can formulate it to play nicely with other compounds and not let them counter each other in short order.
Not so muh interested in of you think its ok to run, more so on the lines of the OP and if it would help with the wear associated with the rockers. To me its a moot point as I will not be running a zinc additive, but just curious if anyone thinks it would help with the rocker wear.
All I'm saying is that auto engine additives are a minute percentage of the industry. We get the leftovers. Sage advice coming...Toren, you run a business, go to bed.
Also lots of info to read when anything oil related is brought up!
So far from looks of things, zinc will not be much help, if any, in keeping the rockers alive longer.
I think I may be looking into a few of those additives tho. Thanks guys!
