Pulled the plugs tonight and put the cap back on. We'll see tomorrow if it pressurizes.

Dye was used to find a leak at the waterpump bypass hose to the manifold. Successfull.

Motor has sat in a garage with temps varying from 55 to 75, no cover.

Battery disconnect has been disconnected for 2 weeks.

Heads were re-torqued at 1,000 miles and I currently have 2,100.

Cast block, aluminum heads/ manifold.

I do get a fairly big mess when I released the cap after the pressure has built up.

Cap and surface it seals against are good, 2 different stant caps everything the same.

Nothing else under pressure in the car.

If the pressure does not come back, I will do a compression test on the cylinders, but I am betting it is still there.

Can anyone help with my plug readings?

I pulled my plugs tonight to diagnose the mysterious pressurizing coolant system.

Any input on how to correct what I am seeing with the plugs I just pulled.
Pics just loaded in my gallery are a lot higher res than I can attach to the thread.

#4 is a shiny brown and was wet with fuel. # 7 doesn't look right to me, all the rest look like they are doing well.

I'd post pics here but they can only be 39kb.

Any input is greatly appreciated.
