ambest at jubitz in portland or. any idea if they are a good shop?
 

Just took a 1985 International co9670 to this shop for dot inspection and to repair some leaks. They steam cleaned the engine and identified some issues I clearly agree with, but also said the oil leaks are coming from all three heads and the engine should be re-sealed. It has 580,000 original miles on it and, although not run hard, not maintained as well as it should have been. I will be running 11 western states w/it.
My thoughts are to replace the obvious leaking gaskets, (valve covers & oil pan gasket) and fix other minor issue I know are needed. Then run it for 100 miles or so and re-inspect.
It has no water in the oil, no white smoke from the stack, and runs very strong for a old truck. Engine has not had any major work. Two previous owners who hauled event stages for concerts, shows, Special Olympics, and stuff like that.
Thanks in advance for your opinions!
