Does anybody have any experience with this? TerraClean

I wonder if it would work to get rid of carbon deposits in the rotary...

I sent an email to the company, inquiring about this service and asked about doing it on a rotary engine. Their response made me scratch my head...

"Rotary engines can be problematic. Because of their nature, they tend to both collect carbon and wear at the same time. A TerraClean service will definitely eliminate the carbon. However it could decrease engine compression as the carbon on the wipers helps maintain the compression in these engines. This isn’t an issue on regular engines, but I am very hesitant to recommend this on a rotary engine."

This is the first time I'm hearing that the carbon deposits can be beneficial for the compression
Doesn't make much sense to me...

Just saw your cross-link from RIWWP's thread.

replace "wipers" with "apex seals". what they're saying is that hard/caked carbon build up on the housing wall (and on the apex seal itself on it's leading edge -- that's a first) disguises low compression because it provides a surface for the (assumedly) worn apex seals to ride on.

Remove the caked on carbon and the seals are no longer contacting the housing wall.

Although I would have to agree with 9k that the housings don't get carbon until the seals are no longer touching them...
