Alrighty... I've had my D15B swapped in for about 3 months now and finally worked out the issues, or so I thought. I was mysteriously loosing coolant again and the car wasn't warming up like it should. I just found out why. I parked it where I could see any leaks and ran it until it warmed up.
I discovered what might be 2 problems. Firstly, the water pump is on its way out. Coolant was puddling from the pulley side and I could see it leaking from behind. That isn't too big of a deal.
My main question is this: I took the cap off when it was warming up and it was foaming from the radiator.
So, do I have a compound problem of a bad waterpump plus a blown head gasket? I pulled all the plugs and they were all a good color. I can't smell any antifreeze from the exhaust, but I do see white (no cat and it's cold out... any help there?). Or is the waterpump somehow pushing air back into the system?
