So about 2 months ago i rebuilt the head (ka24de w/ 233k), during this period i replaced a ton of parts and it ran amazing for about a month and after that it started to develop problems such as over heating.

All of the parts i replaced:
headgasket
valve stem seals
pretty much every gasket i had to remove
relapped all of the valves
new mishimoto radiator
new thermostat
new water pump
had to bypass the heater core as it was clogged and i have no use for it anyways


The problems:
white or blue smoke (really hard to tell) during high rpms, 5k+
overheating at idle and driving but not all the time, only way i can cool it down is hold the rpms pretty high for a little
rough idle
loosing oil but my valve cover is leaking so i am not sure if i am burning oil as well. I would fix it but one of the valve cover bolts closest to the firewall broke off inside (Car came with it broken) and i cant drill it out unless i pull the head again.
The car does run a little rich because i adjusted the dissy to run a little advanced (in hopes of a couple of hps)


What have i done?:
i have bleed the coolant a million times!!!! its usually fine for a little and then starts overheating.
I have looked for leaks and i dont have any, not a single one.

Someone pls help i have spent hours pulling my hair out trying to figure this out.

If it overheats at idle, and giving it throttle will get it to cool down, you have air in the system. One of the most annoying engines to bleed i know.

Have you ever had to bleed a g35 sedan?

Anyway, OP, how's your clutch fan?

Invest in one of the coolant funnels. Best thing I ever did for my KA.

That aside, if you're still burning oil. Check your valve guides. Been there. Done that.

Did you install all of said parts yourself? If so, are you sure you have your valve stem seals fully seated?
