On an 83� water-cooled Westy the coolant level repeatly rises and
ultimnately overflows.  The system has been carefully bled per
instrucitons in the archives, but the problem recurrs.

I suspect that combustion gases are getting past the piston gasket and
into the coolant.

Is this a problem others have experienced?

Is there a test that might confirm this?

Is retorquing the heads likely to help or am I looking at replacing the
gaskets?

TIA
