Head gasket question

Ditto re-torquing.  What that gasket shellac looking stuff is, is a smidge of blow-by discoloring the copper spray on its way out.  I learned that re-torquing on older engines should be done after the first heat / cool cycle before driving anywhere, then again after the first road use reaching operating temperature.  Then "it wouldn't hurt" at 100 miles.  The re-torquing at 100 miles never had any results on the engines I've done.  There are probably scads of re-torquing techniques that all work, but it definitely has to be done.

Warmed up the engine today and re-torqued the head studs.

 

It did need the tweaking!

 

Cleaned off the discolored spot.

I'll keep an eye on that area.

Clay:  I was talking to one of the members in the MD chapter of the National Desoto Club and he does repairs also on Packards. They had rebuilt and engine and torqued it to specks. Then came back to the engine a couple of days later and found out that the head bolts had to be retorqued.  You might have to do these process a couple to time to get everything tight.
