Abstract: Once again, the stacks on my 912 are cracked. A three-year-old part, straight from the factory: treated with black ceramic coating. (And, yeah, I had the prop balanced.)

Thread Title : 912 cracked stacks...ceramic coated, new source?
Once again, the stacks on my 912 are cracked.
And assuming the pipes underneath the ceramic *are* cracked, who would repair them?

Is is possible for the ceramic on coated pipes to crack and the pipe underneath still be quite viable ñ- as strong as ever?
There's one quick way to tell. If you have a shop vac that also will blow air (usually you have to switch the hose to the outlet port) you can duct tape the shop vac hose to the stack and blow low pressure air into it. Take a spray bottle with soap/water solution and mist the areas where the cracks have appeared. If it's cracked all the way through the soap will bubble up as the air escapes through the cracks. If not, it's likely that just the ceramic is cracked.
