I already ordered the Nismo one for the fack of it... And another thing at the back of the motor near the firewall it sounds like its bubbling up from being to hot..
same shit happened to mine... but my water pump was leaking out the collant at tthe same time, dont worry about the headgasket worry about the entire head... mine went up and down about 10 times then the motor went kaboom.... needless to say i had to rebuild and have the head machined... hopefully u dont have the same problem... get a coolant pressure tester, make sure the coolant is full and pressurize it and see what happens
