found lots of foam in coolant resivor. found that the lid was not tight so there was never any pressure in the tank. I replaced the cap with a TRD 1.3. it was a little less foam a little while, but now it loads foam again. no sign of boiling or oil in water. car runs good.
i just hope its not a headgasket. maby a leckage? bad waterpump?
