With the blow by my engine spews, it must be quite worn inside. Are any of these oils better for a worn engine?

I studied the .PDF document about API rated oils. Here is the boiled-down version... (This is how I teach myself things.)

API C J-4 Category: For high-speed four-stroke diesel engines designed to meet 2010 model year on-highway and non-road exhaust emission standards. CJ-4 oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used.
Optimum protection is provided for control of
  • catalyst poisoning,
  • particulate filter blocking,
  • engine wear,
  • piston deposits,
  • low- and high-temperature stability,
  • soot handling properties,
  • oxidative thickening,
  • foaming, and
  • viscosity loss due to shear.

API C I-4 Category: Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards. CI-4 oils are formulated to sustain engine durability where EGR is used.

API C H-4 Category: Introduced in 1998.

I doubt it has as much blow-by as you think.

Remember, the Vacuum pump that powers the brake booster, the blend gates for the AC system, and the VGT turbo actuator and solenoids is located IN the crankcase, and vents all the air it pulls from the vacuum system directly into the crankcase, and makes it seem like there is a lot of blow-by where there is just a normal amount.

Wow, thanks GordnadoCRD. That is VERY re-assuring. :!:

The engine runs steady and strong so I was surprised at how much blow by it appeared to have.

I will sleep better tonight. 8)

And all that oil laden "blow-by" re-introduced just pre turbo compressor, is the reason so many of us have made use of the Provent oil condensate coalescing filter unit.

It separates the oil condensate in the "blowby" from the clean air, and ducts the clean air back to the pre turbo inlet. Separates the oil condensate away. It can be collected for sample or drained to a catch can, or even (ducted back to the oil pan) :grim:

This product will help your turbo inlet tube from rotting out every couple of years.

Sounds like the same function as the Column on a still. Separates the water and steam from the alcohol. Water drips back down into the mash pot. The alcohol continues through the Column as a spirit to the iced-down collection jar. :5SHOTS:

Very similar, except this case the Provent has physical filter material that gives the oil vapor (water, in the case of the still) something physical to coalesce to, and help it drain off separate from the clean air (the good stuff, in case of the still) and the temperature difference helps it work much the same way in both cases, only the absolute number value (temperature) is relative rather than equal.

You are correct about commercial, tall stills. However, home-grown stills are shorter and employ pieces of ceramic distributed through the Column. The steam collects on the ceramic pieces and coalesce back into water, then drips back down the column. Most of the alcohol drifts through the ceramic and eventually is condensed into liquid.

Fortunately I already bought a heat exchanger for my brewery, one made for beer. However, if you have a taste for some soot-flavored beer, maybe I can include it for one batch. I'll bet it would make one hell of a nasty beer -- and probably deadly too.

(October 8, 2017) Just got serious about replacing the turbocharger and timing belt. Ordered a new Turbocharger from TurboChargerPros.com. I searched this site (Lost Jeeps) for comments about aftermarket turbos and found no negative comments regarding TurboChargerPro.com. The other manufacturers or re-manufacturers did get negative comments.

(November 26, 2018) This turbocharger ran for 2 months when my engine blew up from water in the fuel last year. Last week I installed it on the rebuilt engine (on the stand) and it leaked engine oil into the compressor section while cranking with the starter. This problem may have been caused by #3 cylinder exploding and sucking an exhaust valve.

Anyone have experience along these circumstances?

(I still have the original Garrett which is in good condition and does not leak.)

Dean.

i have had a failure of a turbo on a 425 VM. it is more likely caused by lack of cool down causing oil varnish on shaft that damages the oil seal & bearing. You can rebuild the turbo, the kits are quite good. If you have a lot of radial movement on the wheel it may have damaged it or the housing. Also worth checking the oil return to make sure its not blocked.
