The Nikasil problem ended in the late 90's. There were a bunch of engines, particularly BMW 4.4L V8s that has a problem with the high sulfuric fuels from cheapo refiners causing sulfuric acid that corroded the cylinders particularly the top and caused low compression. BMW replaced thousands of engines with "improved" Alusil blocks. Interestingly Porsche also used Nikasil and had no problems. Maybe their owners didn't fill up at the Quicky Mart? AT any rate the problem went away as the EPA mandated lowering the sulfur content and sulfur was totally gone by 2006.

and kaw had to nikasil the aluminum to go as large as they did

That is why low quality fuels should be avoided in Kaw engines.



Can you expand on this Roadkill? How does poor quality fuel (<definition needed>) affect Nikasil?

Thanks - interesting reading.


Is Nikasil the same/similar coating GM used on the 141ci aluminum engines they used in the Vega back in the 70's?

Got a question

   Use appx 15% non silicate coolant of your choice--- about 16 to 20 oz.


      4-6 oz of a product named "water wetter"
 
      The balance of fill will be DISTILLED water.

  Steve
is that 16-20 oz. of coolant the 50/50 mix, or if using 50/50 mix would I double it to 32-40 oz of coolant?

if using 50/50 you'ld have to double it. Steve

Hey gang,

Fwiw, the water wetter is designed to reduce the film thickness of the cooling fluids within the cooling system.  The film thickness of fluids on both sides of the radiators are calculated to determine heat exchange capacity.

As a Chem E, I was tortured in heat exchanger theory and design for multiple semesters though my senior design project.  I don't have my texts or handbooks available, but given the two alcohols and additives, the viscosity wil be reduced and thus reducing film thickness which in turn improves heat exchange from the coolant to the atmosphere.

As for the water - DI vs distilled, it's pretty well discussed.  I worked in an Ultrapure water lab for the semiconductor industry doing research.  Let's just say that the 18Mohm water made great coffee by extracting every last nanogram of caffeine and flavor.  Even regular coffee tasted good. But, the consequence was the damage it did to the coffee pot.  Ya got to leave a little something in thee otherwise the Universal solvent will come to equilibrium with the metals in our engine (pitting).

Steve, I'll need to do some calcs to see if this blend is good for me in AZ.  I do know a common misting nozzle spraying onto the fins works well on my F250 dragging a trailer uphill in the heat.

Oh the joys of Chemistry.

I'm pretty basic...and, here's what I know...I bought Jim Snyder's C-10, and he said it has Steve's Coolant cocktail in it...it is the coolest running C-10 I have ever seen.

Don't know why it wouldn't work in a C-14. 

As far as I am concerned...end of story.

The Vega engines didn't have a coating, it was impregnated into the aluminum. Then after the block was cast the cylinder walls were etched to expose the silicon.

Porsche made this process work just fine in the 928. GM...not so well.

Sadly, the Vega engine was pretty solid (iron or steel liners) by the time 1976 rolled around but the damage to the reputation of the car was done and so it was killed. I always thought it was a far better looking car than the Pinto.

My ex-wife bought John DeLoreans' book years ago and he stated that the suspension/front end collapsed on the first two Vegas to roll off the assembly line. GM sure put the "K" in quality back then.

Ok back on topic with the next post.  ;D
