Throttle Body odity

Previous owner did not know to take care of it. I bought this car from a dear old women who did other maint. at the dealer and other shops, just not the TB and a few other things. So when I got in there after so many years of use it looked like what I stated above. It's looking better now.....

Yeah it really makes a big diff. I lucked out -my motor (replacement) only had 60K on it when I bought it, but there was a lot of other really bad deferred PM, vac. lines off, too much to list... LOTS! Now you have to remove the plenum, flip it over and let it soak overnight filled with water and Super Purple, what comes out is pure evil.

Depends on oil you use: Obviously the TB/Plenum/runners are only exposed to air, oil vapors, and EGR gases.

If the oem air filter is changed frequently, the oil has a high evaporation point, and the combustion exhaust is optimized [egr only open at highway cruise] not much dirty stuff gets into system.

Think about it.........as this stuff creeps down the runners the gasoline spray washes it into the cylinders.

Keeping the plenum clean adds to engine longevity.

The manual scrubbing gets the TB and its neck clean before you use the BG fogger.........less get washed into cylinder that way.

Keeping injectors clean means less variance in fuel delivery and a cleaner exhaust and less junk going up egr tube into plenum.

BTW: if it's really Teflon applied properly, carb cleaner can't touch it. Go to DuPonts web site and read the resistance charts. Flourine is spooky stuff when you add it to polyethylene or polypropylene.

I had a guy with a Jackson Racing Eaton on a 94-01 GSR. He sprayed carb/tb cleaner into the tb. It ran into the charger & large sections peeled off & were ingested. Keith Taber (Tech Dir @ JR) confirmed the Teflon based coating on the rotor set will be destroyed in that scenario.

Result, average rebuild cost $800.

That means don't buy an Eaton supercharger.

I have a friend who told me the easiest way to clean paint and gunk off a metal object, is to put it in a plastic tub full of soapy water, hang it from a metal chain, and insert a metal annode (rebar) in the water. Connect the positive side of a battery charger to the metal chain, and the negative side to the metal annode. Turn it on, and in about 2 hours, the pice has nothing on it, paint, gunk, grease, oil, everything is gone. He was unsure of where the positive and negative connections go, but it basically causes all the particles on the part, to become charged, and attracted to the annode. He said, if it does not start working right away, just swap the leads. At the end, the annode is covered with all the gunk, that was on the part, and the part is pristine.

I have not tried this yet, but a freind, who restores old cars, uses it to get 40+ years of gunk off of engine parts. He says it is amazing. He told me about a web site, but couldn't remember it. I plan to try this method, when I disassemble my 42 year old truck, this winter.

I wonder if this would work on the Plenum?

That's the same thing they do to get gunk off metal that's been on the ocean floor for 100 years.
