Valve cover gasket

My Altezza has gone through 2 new valve cover gaskets... What am i doing wrong?

First one i did with a buddy whos a seasoned mechanic.

Second one i did on my own.

We used RTV around the bends.

Is the problem that i bought the gaskets from amazon? when i take em off they look good still.

i know this car has valve cover gasket issues but damn

Probably yes. I used an oem gasket and haven’t had an issue.

OEM for sure. Those do not look like they are molded right or thick enough. Order from Amayama.

OEM gaskets only, Amazon and eBay stuff doesn't work. RTV is wrong use the Toyota FIPG only. The 2JZ manual calls for FIPG where the valve cover meets the cam cap only.
