I had overheated the car but not badly, I shut it down quickly.

I had the mechanic replace the radiator, had the cylinder head rebuilt
plus new head gasket, timing belt (84,000 miles) and water pump, new
hoses, new radiator fan, etc. I asked the mechanic if the bottom end
(block/pistons) could have been damaged before he started the job and
he said they never get damaged. He said they are strong. He
specializes in Honda and Toyota.

The engine is very smooth. The repair was about two months ago but I
noticed I have oil in my radiator with the milky coffee look. I
flushed it again and the "coffee" came back the same day.. I also
added oil because it was a little low. The mechanic is an honest guy
and a good mech. I am taking it back but I am wonder what it could be
beside even more money to shell out.
