Any oil additive help with blowby?

[WarWagon]

I know rings and deglazing the walls will do the trick. :rolleyes5: Don't want to do that at this time.

I have an estimated 60K on the 6.2 engine and am getting smoke out the dipstick at idle.

Any oil additives I can try for stuck rings?

zinc

Elaborate please?

I've been using Auto Rx. Seems to be doing the trick, you have to order it online.

All of the 7.3 and 6.9 idi guys swear by it.

Zinc helps the rings seat better . And that means less blowby.

Check the tuna can on and mess filter in the valve cover for being clogged.
60 k is barely broke in,should not produce blowby unless you got a couple broken rings,..snakeoil won't help for that or anything else for that matter.

How is it used and how soon, how did it work?

Does the blowby come out evenly or does it puff or pulse?

You add it to your regular oil change and run a normal change interval. For my 95 that is when I am 1qt low, 3-5k on dino. I am running Rotella 15/40 because that is what it recommended but have 5k on this oil change and have not yet used a full qt and oil still looks "decent" for a 6.5 w/ 180k on it. I will likely change back with Delo 400 since I plan to put the engine in a different truck soon.

Ww, is this in your 93 that gets the tar worked out of it? I was hoping the gapless rings would help this problem.

Gapless rings? If you have gapless rings an have blowby, i have a feeling an additive won't help that. Although it's worth a try.

This is on the 1995 with the surplus 6.2 engine. (The 1993 with gapless rings has zero blowby.) The 1995 has a steady smoke from the dipstick tube. No puffs. The mesh was cleaned when the engine was installed as I needed the 6.5 valve covers. May have to install a 2nd CDR...

This was the engine that blew enough oil out of the orange tube to have the ATT get a redesigned intake tube.

The other surplus 6.2 in the 1993 had partially broken in 2nd rings as the bottom half of the rings still had the break in coating on the ring face. Don't know if light load does this or the 6.2 rings hate the turbo being added later? The gapless rings and deglazing took care of the blowby in it.

I'll look at the CDR system again as the tube was extended for the HX40II install and may be a restrictive design.

x2 for the AutoRX. They are not cheap and it is a slow process because you have to drive the truck and let the oil circulate.

Of course, it will not fix any mechanical issue inside the engine.
