Thermostat Housing Leak

After about a dozen start ups on my rebuilt 230 I re-torqued ( at running temp. ) the 21 head bolts as directed in manual.

 

That went fine , however several days later I noticed # 1 spark plug recess was filled with antifreeze.  Mopped it up, and waited a few more days, full again.

 

So I have re-torqued the two thermo housing bolts.  They were well below the torque specs.

 

Makes sense after some thought.  The head was lowered away from the thermo bolts.

 

 

Hope this does the trick so I can avoid draining and changing the thermo gasket.

 

FYI for you rebuilders.
