~V8~ Mystery slime in my 97’s ~V8~

So the problems iv been having with pre ignition and over heating had finally boiled down to a lean condition.
I pulled the two 97’s apart and found this.
A nearly enviable clear thickish slime in the bottom of the bowls that when dry looked flaky and white.
Obviously obstructing the jets and ………..

So what the hell is this stuff?
And no I don’t love my Stromberg’s like that.

Do you have sealer in the tank? I'm hearing bad things about the new crap they sell called gasoline eating tank sealer.

 

The only thing thats ever been in the new tank is gas and air.

 

Did you use any RTV silicone anywhere on the fuel system?

 

Nope
The only thing in the system now that I think about it is the filter and about one foot of hose.
Maybe its glue from the filter.
I’m going to cut it open

 

I had a element in one of those clear inline filter come un-glued here earlier this year. My 65 Ranchero had a terminal vapor lock prob this year untill I put a return line back to the tank on it, last year no problem. I think they have fucked with the fuel formulation this year, and not for the better.

 

Was there any type of finish on the carbs (clear coat, paint etc..) that might cause the problem?

 

was plumming my engine to run in the chassis, had some tiagon clear tubing from a gas can
it had gotten looped into a coil just south of the carb
when i came in the shop the next day, the fuel that was left in the loop from running the
engine had turned black from being clear less than 24 hours.
Don't know what the solution is?

 

Could be your tubing being attacked by the fuel!

 

Don't know what that crap is. All I know is I see a lot of it in small engine carbs that have set for a while. Especially if there is a small amount of gas in them. What a bitch to clean out. Seems to eat the bowls out also.

 

Interesting

I’m glad someone else has seen it, I was starting to think I was crazy.

So I cut the inline (at the tank) filter open. (NOS 70’s fram)
No sign of the jizzz on it and the glue holding the paper was solid and brown.
Standard 5/16 from NAPA fuel line looks like new inside.

No clear tubing anywere near this car.

Carbs soda blasted when built (no paint)

I did note that when I pulled the carb tops that a lot (&#189 of fuel had evaporated off in two days.

Could this be some shit that develops and is left behind when fuel gas’s off?

Who the hell knows what there cutting our gas with. $400 a gallon for shit, were fucked.

 

Here in the northeast. We got the 10% ethanol. The name brand stations are OK. Most of them. BP sucks.
Along with the 90% gasoline is 1.3% benzine and 10% ethanol, I know that's more than 100%. So it's like 88.7% gas. Now NJ alows 6% of the ethanol to be water. So in an 8500 gal load that's about 50 gals of water.

Used to be water separated from the gas and we used the water paste on the dipstick to see how much water accumulated in the tanks, then when there was 2-3 inches, we'd pump out the water, cause it didn't mix.
Now the water is dispersed in the fuel. It don't fall out no more.

Now the habibs have figured this out and the off brand stations have been caught with garden hoses putting extra water in the tanks, Really, in my county alone they have caught a dozen stations doing this.

We see a lot of cars where the filler door opens and the compartment there is covered in black mold. We didnot see this before the ethanol era.
Who knows what is going on in the tanks with the mold.
Years ago, there was a contamination problem with Diesel fuel with a mold that lived in a no-oxygen environment. It would turn the fuel black and plug filters.

I've seen the small engine problems, too. The landscapers have to use name brand gas now because of this.

You maybe should sample the gas you buy, put it in beverage bottles with the caps off and see how it deteriorates. And keep the caps on some and see if after time, if water drops out to the bottom.

I bet you got an excess of water or mold problem.

Very interesting post. What exactly is the black mold? It's been eating my paint for 4 years maybe. Bad on older cars with non sealed vapor systems. 1/4 of the car can get covered. Maybe I'm nuts but I think I see it on house roof shingles, too, especially light colored ones. I wonder what the health issues are as well as contaminating food growers crops?

 

the only thing that leaps to mind is varnish.... has this car sat for any length of time with fuel in the system? and like alot of these other posts, i wonder about the formulation of new fuels and what kind of "mutant varnish" they may be producing.... i'm just glad they saw fit to remove lead and replace it with literally DOZENS of un-pronouncable chemicals (for our safety)... i guess they'll know more in another generation or 2 when kids start sproutin fuckin gills and arms on their foreheads...we ARE the experiment at this point!

 

I don't know what the mold is, but the cars that we fuel regular and the customers that don't shop around don't get it. But the customers from Hess, Delta and BP all have it. Shell and Exxon are OK, from what we see.

It's on late cars that have sealed caps, too. But maybe they don't seal too well?

I really think it's something living in the fuel, but What? and not in the name brands.

But it's OK cause our gov't is looking out for us

 

It gets run every week (20 or more miles)

I worst part was it didn’t plug the jets totally. It made me waste countless hours on other stuff.
Sure am glad I didn’t pull the heads.


Thanks all and G pumper thats some wild info.

 

Has anyone noticed how an open container of gas doesn't evaporate like the old days? And in a few days it smells more like kerosene or turpentine then gasoline.

 

Residue from ethanol was one of the first things that came to mind but it didn’t quite look like the stuff I remember from my sprit car days.
I have never let it get past 210, to much $$$$ in this old flathead.


Yes the government is sucking bad. I’m getting real tired of being the consumeE.


When a vehicle is powered solely on ethanol is the same as methanol. Is the volume of fuel basically doubled over using gasoline?
If so how the hell could we ever grow that much corn??

 

You said that you soda blasted them..Did you clean them real good of any residue from the soda..Soda and fuel when it dries will look like chock, white powder, and if not totally dry with be thick to the feel..I have cleaned several 97s for customers that someone used soda..

A few years ago I was in a Briggs & Stratton update class. They were very emphatic about the quality of gas. They said in no uncertain terms, DO NOT USE REGULAR!!! At that time it started to deteroate in 2-3 weeks. I have noticed since then if you don't use hi test in small engines it lasts about 1-1/2 weeks. Then it screws up the fuel system. Most noticable was the ARCO. It wouldn't even let you start your mower!! Fixed a lot of no start problems by putting fresh hi-test in them.

Yes, I am a certified B/S tech, along with Tecumseh and Kohler, and most chain saw brands.

 

I deal with old cars, old bikes, old forklifts,etc. everyday. (And old people) LOL.
It's who we are and what we do.
Bottom line is this....If you do not drive or use gas powered stuff EVERY day, the fuel will distill down (evaporate) almost overnight.
The gas formulation we are forced to use is crap. Less of a problem on newer cars with totally sealed tanks and vapor recovery, but still an issue.
My solution is to treat all gas i buy with " stabil".
I have a beautiful 67 buick skylark in the shop right now with a varnished tank and carb. It's been in and out of the body shop for about 3 years. This is the third car in the last 45 days that i have had to clean the tank and carb on, and i have had to do this at least 10 times ( bikes and equipment) in the last 60 days !
Gas going bad less than a week in an open container. They charge us more $ for less quality, make record profits....
Enough rant Dave...
