So what is the proceedure for testing for cracks? remove the insulatin and run a leak test by covering the eshaust or dye penetration or is it quite easy to see visually? Sounds like quite a common problem.
Do you think it is to do with poor cooling monitoring ?

My exhaust stacks started to crack at about 375 hrs engine time.
An early sign was a grayish-white powder on the exhaust wrapping and nearby engine parts by the first bend of the stack.
Welding gave me some time to order a part.
A few months later the other stacks cracked. I should have ordered the full set on the first crack.
My original stacks had a weld along the bend - not a good design! The replacement parts looked better.
I am now approaching 750 hrs of engine time. The new stacks approach the time the old ones failed. I hope to get a little more time out of the second ones. I am looking for gray matter during preflight and visually inspect the stacks every 50 hrs.

Dear Xoggers,
Hello again after a long absence.
A few years ago I had alot of probs with my old pipes. Anecdotally none
lasted more than 400hrs, ( although I got five-hundred-something). One front side is far more susceptible to cracking
if you look at the acute angle. It seems always to be at the elbow past the
manifold for obvious reasons. AMT redesigned this elbow, to be minus one
centre weld, which improved longevity.
I wrap my pipes with two separate
pieces of bandage now; starting from the muffler and secured with a piece of
lockwire a few inches from the manifold. Then I start with a second piece
and finish it at the manifold. I then secure the join and the end with hose
clamps. You can then remove and discard the small top bandage at more
regular intervals for inspections.
If you get a crack at a weld you can buy a "donut" to cut curved a piece
that may be welded in below the manifold attachment.
BTW the issue was worsened by a vibration problem that no-one could diagnose. Tried all the usual but was near 600 hrs so removed gearbox for scheduled maint; this was the problem.
Cheerio,
Sandra.

The stacks that came with KIR are stainless steel and were coated with
ceramic (by a local company) by the previous owner. I am up to 530 some
hours now with no sign of a problem, but I have no idea when they were
replaced from original. (I have over 300 hours since purchase.) The original
pipes are welded on the bends where the new units are not. Paul P.S John. My
pipes are not insulated.

Hello Mangoflies,
I have often wondered about these lame cracks that are reported to occur in the 912/ ximango combination.. The insulation tape, as you know is hard to remove without destroying its reuse so I have tried to inspect regularly without removing the bandage. The recent emails on this subject have worried me enough to now remove the bandage and I do not have any cracks or damage to the exhausts and the engine has done a total of 600 hours. The question arises what causes some to crack and other to escape the trauma. Gets pretty hot here in summer so I am careful to idle the motor for a minute or two before turning off the engine. So I am still uncertain as to what causes the cracks. My main operation concern is very gusty wind shear conditions close to the ground as the Ximango is very heavy.
On a more delecate note what is the future of motor gliding and what sort of MG's will be flying in 5 to 10 years.
Best wishes john t
