Attempt #4 on the Turbocharger's Gasket

The turbocharger's gasket has a small coolant leak--again.  Over breakfast we discuss what to do about it.  However, with a thousand miles of uphill river infront of us, the answer is pretty clear: repair it now.


Read the Small Print: Turbo Side

It's always nice to find a smoking gun to make you confident in the diagnosis and repair.  Turns out there were two smoking guns.   First, the gasket was on backwards.  I now know it's important to read the small print in contracts and on gaskets.


Corroded Turbocharger Surface

Second, there's noticeable pit corrosion on the turbocharger's mating surface.  Fortunately the fixes are straight forward: reverse the gasket and put RTV sealant on it.

Tomorrow we'll take Nellie out for a sea trial to confirm the repair was successful.
