After my Nismo thermostat started sticking, causing my engine temp to rise, we switched back to the stock thermostat, flushed and got all air out of the system, and its been fine since. No coolant blowing all over, nothing. So, maybe your just getting a thermostat problem. Keep an eye on that temp guage.

No, there was none found. Although with the APS reservoir its kinda hard to see in there but a general look didn't find anything.

not for driving on the street. you kill the ability for the water to absorb the heat. this is a trick used by drag racers for years. but ONLY should be done on a all out strip car and never on the street.
