I think that he is referring to the tan deposits. These type of exhaust joints always have some degree of deposits visible, since the joints move slightly with expansion and contraction of the exhaust. As long as there is not an excessive amount (the deposits on my exhaust are 18 years worth), I doubt there is an issue. If there is a question of a significant leak, your mech can pressurize the exhaust and paint the joints with soapy water to look for bubbles. We do this at every Annual Inspection.

This looks similar to mine. I think they all seem to leak a little. Not sure how much is too much. Any time a mechanic says something like all 16 need to be replaced I would ask in person to see it and have him explain it. I suspect he is clueless about the excessive cost and thinks they are just a low cost consumable part.

I would disassemble, clean, inspect, and reassemble with new nuts, bolts, and washers. Then monitor it at closer intervals like 10 hours then 25 hours.

Hi Lance,

This is exactly what happened.
It only costs me the new screws so far!

Thank you.

My mechanic told me the clamps are identical to much cheaper Cessna clamps that they have on hand...

When I called Acorn they told me that they are pretty similar but not exactly and in case of change the form1 will say that it’s for Cessna

If it ain’t broke don’t fix it. Replace only the one(s) that are bad.

They all leak a little over time and if they aren’t cracked or worn down to nothing what would make a new clamp any better off?
