I'm rebuilding a turbo and the exhaust turbine is caked in carbon deposits.

My only experience of decoking is pistons in Mini's which were much easier as they were pretty much flat and gentle scraping got the deposits off.

With the shape of the turbine it's proving a nightmare - does anyone know of a quicker solution - are there any wonder chemicals I should know about ?

Many thanks

 

I've previously used oven cleaner on cylinder heads; put it on, give it a scrub, add some more leave it overnight, add a bit more, scrub it some more and finally wash off with water, dry, preferably with compressed air and give a light coat of wd40 to stave off any surface rust if its going to be stored before assembly.

Although oven cleners of today are somewhat limp wristed as due to the makers not being allowed to use those toxic chemicles like the good old stuff had

My Dad suggested giving this a go too - the thinking being, oven cleaners designed to deal with baked on carbon - like exhaust deposits perhaps ?

White spirit doesn't touch it. Perhaps pro bead blasting is the only real option due to the limp wristedness of moden oven cleaning stuff - shame but I could do a report for Which.

Thanks

 

Have you tried dunking the turbo in coke and leaving it a bit then, washing off with de ionised water or Isopropyl Alcohol. This is how we clean the gas parts of rifles when were feeling particulary lazy, and they have had some heavy use.
