Re: [Amc-list] Amc-list Digest, Vol 15, Issue 44

["Steven Fox" <bikerfox@xxxxxxxxxxxxx>]

Bruce,

I had a similar issue a couple of years ago. The shop I brought the car to 
made quite sure that the "coolant inlet on the block" was quite flat and 
they also made sure that the "thermostat housing" was flat as well. Used one 
gasket, no permatex, and never had a leak since.  Hope it works for you.

Steve
