All,
I just tore down the spare turbo I've had sitting on a shelf for a few months now. After lots of PB Blaster, and liberal use of a rubber mallet and a large brass drift, everything is now apart. The center bearing housing was a nightmare to remove, as gobs of baked on carbon had virtually welded it to the turbine housing mating surface. The thing is covered in baked-on grease, carbon, rust, etc. So what should I use to thoroughly clean the innards? My preference is towards LESS scrubbing, if at all possible. And no, I don't have access to an ultrasonic parts cleaner. |

u might try a very fine sand paper or wire brush to work on the chunks, and then soak in an engine degreaser....

perhaps some oven cleaner or the gasket remover spray they sell at the parts stores.

i would suggest going to your local machine shop and getting both parts of the turbo hot tanked (the compressor side aluminum hot tank safe of course) then coating the exhaust side of the turbo in a heat paint.

B100 biodiesel is a remarkable solvent -- but don't throw any rubber seals in there.
I've also had good luck with the "purple power" brand junk you can buy by the gallon at any auto parts store -- I use that for general degreasing and mopping my epoxy garage floor now and then. Cheers, John

Oddly enough Spraynine is an excellent degreaser. I use it to wash my engine. It is a little hard on aluminum though.

You know those buckets of carb cleaner snot that they sell? Ive soaked an entire small turbo in one before that refused to come apart. Took a couple of days, but the carbon practically fell off, and it doesn't harm aluminum terribly with long exposure, since most carbs are aluminum. Media blasting does wonders for the housings afterwards, just be sure the parts get baked and washed to remove all the media if you take that route.

I second the B100. Nothing I've seen degreases as well as biodiesel.

Best degreaser, acetone. Use gloves, and lots of ventilation. But it will remove just about anything.

I try to use Simple Green when I can, but for the bad stuff I have to use Greased Lightning. This stuff works great and is cheap, but do not get any on your rims or paint, it will take out the shine! I buy both from Sam's by the gallon.
Also, if I can add a thought? You can buy cheap buffing wheels for your hand drill to polish up the turbo. Now could not be a better time for it.

The best de-greaser by far is antimatter. You just need to be careful not to annihilate your self or apply it to quickly. Watch out things will get very hot if your not careful.

Just a newbie here but what works for me is applying all of these in this order 1)Simple Green and rinse 2) Gunk 'Engine Brite' then scrub as needed and rinse 4)SprayNine 'Grez-Off' and finally rinse well... All of this of course with the usual caveat of avoiding direct spraying of contact wires etc...

Don't they sell that at Wal-Mart, next to the transporter beams? Or is it over by the blinker fluid?
