Oil cooler has been removed and I have inspected the unit and pulled out the valve and checked it was working.

As for blowing air through the block I think I was blowing into the right port but not 100%.. plus I need another person here to see if there is any pressure at all on the other side?

Right now I feel like I am fumbling around with my you know what in my hand??

I am so frustrated by this shit.. I had to remove the fuel lines from the injector pump and the starter motor to get to this bugger and is a real pain.

I am not sure what I am doing now?? oh thats right cooking dinner.
