I can run the car hard temp about an 1/4 inch above the C, park it and pull the motor oil dipstick and no smoke. I drive the car around the city for about an hour, the temp reads between the O and the R closer to the R I park it and pull the motor oil dipstick and some smokes comes out. No smoke out the tail pipes or anything. What is happening? Any suggestions? Sorry if it sounds weird, but that is the only way to describe it. The temps around here are about mid 80s to low 90s. I am using semi synthetic blend 10w30. I do have under drive pulleys. Thanks for any help.
