I had the radiator cap off during my test yesterday and did not see any bubbles this time; strange. Duncan, I plan on trying the exhaust manifold off test after I do the leak test in coolant. Will shoot some video and post then so you all can hear/see what I am dealing with.
I guess I will just wait for the head gasket leak detect kit and try that next.
When injector pumps gunk up, where typically does this occur within the pump? I
Can you unscrew the delivery valves and clean them while the pump is still on the motor? Do they take special gaskets or seats like the injectors do and are they serviceable like the injectors are?
Has anyone had better luck using the newer injector seats that look like a smashed donut vs the convex original ones? The new ones look like they crush on both sides vs just the convex side on the originals.
