Re: [DML] Coolant system pressure test results

[Martin Gutkowski <webmaster@xxxx>]

Let me get this strait.... you performed a pressure test BEFORE you ran 
the engine up after replacing the head gaskets?! Oh dear. The head 
gaskets have an adhesive in them which bonds the mating surfaces 
together and only works once the engine has been run up to temperature; 
the adhesive flows and the head gaskets are properly bonded. Now you've 
gone and forced water between them in places, you should seriously 
consider stripping them back down to dry them off and replace with new 
gaskets.

If it makes you feel any better I've done a similar thing where we had 
to strip one head off again after filling with coolant.
