July 26, 200520 yr Ok, what causes the coolant to foam up? I've been having cooling issues with my 1986 Ea82. Today I warmed her up with the radiator cap off and when I would rev the motor up the coolant turns into a milky color. First thing I think of is the water pump. Would a bad pump cause cavitation? Or maybe a leaky Head gasket? Help! Thanks,

Or maybe a leaky Head gasket? Help! Thanks, When oil and water are mixed, they form a miky substance. I used to use that water/oil combination on a mill when cutting aluminum. The foam is caused by an air leak into the system. The one thing that can cause this is a blown head gasket, with the damaged part of the head being near an oil passage.
July 26, 200520 yr This is the next step. It goes from coolant, to foam.... to I'd say its a head gasket thats gone bad, that would account for the overheating as well. Have you checked your oil as well? Might want to drain it and see if its milky or foamy as well. -Brian
July 26, 200520 yr Author ohh.... dang :-\ Alright, that was my fear. The oil is fine and no white smoke. Oh well, time for some more work on the subies.

July 26, 200520 yr Only one of many. We have way too much work to get done... will take more than 1 day (which is all I got to spare this week). -Brian
