A few weeks back we found coolant in the oil. Suspected bad head gasket. Pulled apart. Took the head to the shop for usual checks and work. Everything tested good. Installed a OEM Toyota head gasket kit. Didn’t see any signs of head gasket failure. So, replaced all seals and gaskets for oil cooler as well. Put it all back together, compression is good. Runs good. Took it for a 10 minute drive and found more coolant in the oil.
It’s a 1FZ-FE.
Is the oil cooler bad? Just some residual coolant in the system?
