I ran my 20B at
idle, till about 160 degrees. My water pressure rose up to 23 lbs. That seems
excessive to me, but I've never watched water pressure before. I've bled the
block a couple of times and I dont feel like I have an air lock. Heat is even
throughout the radiator. I was a bit worried about compression leaking into
the cooling chamber, but I'm not loosing any water, the plugs aren't wet, and
it starts flawlessly each time. Hot or cold. Recon I'm all worried about
nothing?
