Anyone used Penisol to loosen up a carbon-choked TDI intake manifold?

Leaking turbo seals?

Ah, no, not my TDI... just thinking ahead, and borrowed an image for effect.

I reduced the EGR as far as I could when I bought my TDI, but when we did the Timing Belt a while ago, I still saw a very mild amount of carbon building up (@70k). I'm thinking about a turbo upgrade, and that would be a convenient time to clean out the manifold.

No, that is normal for a TDi, mine looked like that at about 60,000 miles, cleaned it manually then used a VAGcom to turn down the EGR duty cycle and haven't had a problem in the 210,000 miles since.

Mine's got 435k kms.

I'm afraid to look.

Sounds like what I would use to clean the junk out of my junk.

I think I'd use welding gloves rather than latex gloves...

Next time, I will try putting the parts in a plastic freezer bag, so I have to use less Pinsol, then put the whole package in a bucket with padding to keep the bag from bulging out.

Googling about the white residue, some sites identify it as oxidized zinc in the bottom of the bowl.

I might have to see if I have any old carb parts with that white build up and test the "Coke theory".

More "Redneck engineering"... my bucket has a lid closed tight on it. I might put it next to my air compressor and turn it on. Let it vibrate the cleaning bucket a bit.

If you put the parts and pinesol in a freezer ziplock bag, and leave just one corner of the ziplock cracked, then immerse the whole thing in a bucket of hot water. The pressure of the water with squeeze out any air in the bag. Close the last bit of ziplock before it goes under---and/or just don't let it go under.

There exists something called "white rust" that happens on aluminum. Common on old BMW airhead engine castings in moister climates. Almost impossible to stop. if you see this stuff in an aluminum carb bowl, try adding gas dryer to your gas (although most gas has plenty of alcohol already).

The amount of Phosphoric acid in soft drinks has been reduced considerably. It eats teeth. It you can find some really old Coke, it will have more carbonic acid. This develops over time from the CO2 disolved in the drink. Might be good for something. I just keep a gallon of hardware store phosphoric around. Easy to mix up various dilutions for various tasks. You can also use Aluminum Jelly which is some sort of corrosive stuff in a jelly form. (I just looked on my jug of Phosphoric. It ill etch aluminum and is used for a paint prep. I'd keep it off the bright stuff)

I would say if you have white corrosion (not a deposit, actual corrosion) in the bottom of a bowl, you can clean it but it's coming back. I'd just do some soap, water and a wire brush to get off the looses stuff then run it and see how things go. If it was the result of moisture and the gas is keeping that at bay, great.

Has anyone tried it in their parts washer yet? Im picking one up tomorrow and need to put something (water based) in it. What strength would you go with? Would 50/50 be too weak?

50/50 seems to be the preferred strength.

Thanks for the reply, also, does the dollar store stuff work?

Not nearly as well, according to those that have tried....go with the brand name Pinesol.

Baptized my naked r75/5 case in Pine-Sol (roughly 50/50 mixture with hot water) for about a day.

Followed it up with a thorough utility sink flushing. Had to scrub some areas on the case exterior, but the P-S did most of the work.

I let the stuff sit in the Pinesol (no water) for a few days, then pulled it out and gave it a quick once over with the toothbrush. I figured it would work, but I didn't think it would work this good!
