You can't make this up
The cooling system on the car is closed circuit quackery. I got comfortable with the mediocrity of it.
This should have been the gold standard for ever :clap:I went through this a few months ago. It's a tough problem to confront but I would just bite the bullet and pull the engine. One definite recommendation is the gasket which failed on mine was the aftermarket version sold by JAE. The second time around I went with the Goetze (sp?) gasket, new ARP studs and I had Cedric my head expert check that everything was flat and while it was in his shop I had him do the exhaust valve guides which he thought needed attention. After all was said and done (I get shipwright's disease really bad - redid the bearings and had them coated by Swain Tech, did the rings too) the car runs extremely well and I am very happy. Oh, and I did a oil filter relocation so now I can actually change the filter and not get oil all over the engine every time you spin the filter off.
