I have an 01 outback with 310hp carb. July 5th I sucked a weed through the strainer and it got stuck at the transmission cooler. I was driving and check my gauges often so it wasn't hot for more than 2 minutes-but it was without water. I changed plugs and oil and 1 burnt out silencer. about 1 ounce of water in the oil, but that happened ocassionally before-I think from the drain hose laying in the bilge. Ran ok, started harder than before but smooth after warm up. Now the engine makes a clacking noise from what I believe to be the valve covers. Anybody know what I got, or what else I should check after running dry. new impeller is going in tonight.
