Snake Oil Science

[FMSPEED49]

Motor cooled to touch

YA'LL READY FOR THIS?

cyl1 105

cyl2 110

cyl3 115

cyl4 115

cyl5 108

cyl6 111

So I guess the answer is = YES IT WORKS LIKE A CHARM

with no adverse affects. also no visual change in the oil.

gonna change it just in case.

Signing off, going driving.

next report will be after a few hundred miles, unless somthing bad happens.

For the supporters, Thanks.

To the others, Have a Nice Day!

[Dennis Hemingway]

WOW!! That's Great.

Dennis:eek:

[FMSPEED49]

I'm pretty impressed all and all. or better yet, STUNNEd, just didnt see it doing that well.

Hey whodda thunk we would have had our own version of Myth Busters. Those reading look very good, right in the 10% tolerence range and not to far off from new stock which I think is 120.

So what now oatmeal in the radiator???? Or exhaust manifold cooked road food??? (hint no grilled limburgher sandwiches) So inspite of the Don't try this at home disclaimer we were blinded by the science.

I'm stunned too by the second go round. I'm gonna try this next weekend. Only thing is we dont have Bon Ami here, but I might give it a try with a local cream cleaner that is advertised as being non-abrasive, or close to it.

[Allan Faust]

Bon Ami is based on a different mineral than other Clensing powders ( usually Silicate based). Its advertising used to feature a very young chick (poultry type) coming out of an egg, and the slogan was Hasn't Scratched Yet. The only other one I know of that is based on the same mineral is Bartenders Friend which was used for behind the bar cleaning and polishing glassware.

Bon Ami's active ingredients are the mild abrasives sodium carbonate, calcium carbonate and feldspar.

Yep, right you are, it is a combination of calcite and feldspar which are essentially 2 minerals that have a low "hardness'... essentially enough to use the rings to create a "whetstone" effect, but not enough that they can't be "expelled" by the motor.

Not sure I'd try it with a non "natural" cleanser.... the chemical principles involved (I've been doing some searches) more or less show that with temperature and friction, the natural minerals involved here break down into gases and non consequential elements that can be exhausted easily which shows why nothing was really found in the oil (everything essentially vaporized, vanished, etc...) while with chemicals that "aren't listed" or "trade secrets" as comet for an example, use more complex chemicals that probably won't break down as easily, and may cause more harm than good.

FMSPEED, that's terrific! Considering the nice condition of the cylinders and pistons do you figure the rings hadn't seated well? Great test.

I would not use a commonly available modern cleanser. the abrasives in them are larger and much more agressive than the Bon Ami formula. You might try baking soda (calcium carbonate) and gas solution

[FMSPEED49]

The theroy was due to the cleanliness of the inside of the motor, no sludge in pan, clean piston tops, and .40 pistons, plus i can document the car only has 51,000 orig miles,and had sat for 10-15 years. I figure it "wasn't seated"

But I also figure, If it was using 1 qt per 100m, worst case I was rebuilding it, I even had the machine shop lined up, so I figured I had nothing to lose, If it didn't work, well I rebuilt it, If I didn't try it, well I rebuilt it. But it worked, so away we go.

Btw ran her about 70 miles tonight, no visable smoke in the mirror, runs better than it ever did. With NO adverse affects. More power, Easier starts, More "stable" speeds if you will.

Now on to the aluminum foil helmet I was gonna start on...............

[FMSPEED49]

Also , everything I have ever read, and everything I have ever been told is ONLY USE BON AMI!!!!! DO NOT USE ANYTHING ELSE!!! Is what they ALL said.

I assume due to the chemicals and stuff everyone else studied, (not me, i'll just dump the s&it in) , But my scientific evidence does seem that it may contain MAGIC.

lmao

[Don Coatney]

At the rate of compression increase per treatment in about 6 more treatments you should be up in the two hundred pound range.

It is interesting that in the old days a 51,000 mile engine was a candidate for replacement. Yet today the same engine is not broke in at this mileage. Is it the oil?

[FMSPEED49]

Pull ed the oil this morning, clean as when i put it in, no clouding or foaming at all, but gonna change it a few times just in case.

Also, Now it is real hard not to do it again, Just gotta wonder how high it could go. or how many till it pops, lol

But I am convincing myself to stop, at least for a week, the nsra show is next weekend, and a few big cruise nights, so I better stop now.

[FMSPEED49]

Now here is an intertesting update........

Changed the oil, 100 miles since "medicating" and changing oil afterwards.

Now remember the oil that I started with was fresh , less than 100 miles.

I have a new oil pump, The pan was removed and cleaned 1000 miles ago, with no debris what so ever in there.

When I drained the oil, a 2" x 2" what apears to be, a part of a old tattered rag, came out of the pan, and now the oil pressure is 10 lbs higher.

Where did it come from? hell if I know.

Btw the pick up was removed and cleaned at the same time. So it wasn't in there, but I guess it was somewhere.

Go figure.

[Niel Hoback]

Thats pretty scary, Now you have to drop the pan every time you change the oil just to look for foreign stuff? Yikes, you sure it didn't come outta that Bon ami can???

[FMSPEED49]

Nope had to be somwhere in the motor, when it was rebuild ages ago. Figure it must been up above the crank somwhere.

[John Mulders]

was probably white and screaming "surrender, no more Bon ami !!!"

[Lou Earle]

Could very easily be a piece of rag that was stuffed in the oil fill tube years ago and disintegrated except for that piece? Seems to me like the only place it could enter. I found a screwdriver in one of my engines!!!

Lou

[Normspeed]

If the motor was stored for a long time, maybe part of a mouse nest?

[FMSPEED49]

was probably white and screaming "surrender, no more Bon ami !!!"

That's funny right there.

[james curl]

May sound funny until you pull the pan and discover about a basket ball size wad of cotton. The bottom half soaked in oil and the top half high and dry. I pulled a 41 Dodge engine out of a car that had not been run in several years and the breather cap was missing from the oil filler tube, when I pulled the pan there was the wad of cotton. This car was stored in a barn on a farm where cotton had been grown.

[Don Coatney]

I will double check but I am pretty sure there is a screen about 4-5 inches down in my oil fill tube to prevent big (and little) stuff from falling in the pan.

[FMSPEED49]

Suspect I fifgured it out, The oil cap is hollow, I could have sworn there was a "filter" in the before ( i seem to remember spraying it out with cleaner a while back, maybe 500 miles ago) , I am betting that someone shoved a piece af rag in there, and it sucked it down.

Btw Don, I will slide somthing down to see if there is a screen in the bottom of the pipe, just out of curiosity

The bonami report is, Car runs perfect, no adverse affects and we are at almost 200 miles now.

[Young Ed]

The 23" blocks are just a tube. The only filter is in teh cap

[Don Coatney]

The 23" blocks are just a tube. The only filter is in teh cap

As usual you are correct Ed;

I just checked my 1953 Desoto engine oil fill spout and there is a screen about 10" deep in the spout. The picture does not show it but it is there. I then checked a short block 1948 P-15 oil fill spout and there is not a screen in it. I wonder if the later short block oil fill spouts had a screen?
