My 2000 Ford Ranger 4 liter for haullen the race car (we only have hills on my routes) is approx 1 1/2 inch over the full mark with anti-freeze & YES it's milk brown.

Compression test showed each cylinder at 175 psi. The plugs look ok.

BUT, to make the compression test simpler I took off the alternator & the air intake tube that travels from the air cleaner to the throttle body. The air tube has anti-freeze in it, the air cleaner is wet from anti-freeze & the bottom of the air cleaner box is wet from anti-freeze.

Any experience/thoughts are appreciated.

Tomorow I will take off the upper & lower intake manifold for a look see. Water does travel through the lower intake manifold.

Duh........
