1JZ-GTE VVTI Valve Cover Gasket replacement

Replacing Valve Cover gasket on 1JZGTE VVTI engine in JZX110 Mark 2. It's pretty much same in all VVTI JZ's such as JZX100, JZS171, JZZ30, JZA80 Supra , IS300 etc or even non VVTI JZA70, JZX90 JZZ30 and so on.

Oil cover gasket is usually No.1 suspect of major oil leaks on JZ engines. "Usually". In my case it unfortunately didn't fix oil leak(s) as engine leaks from every possible seal how it seems. I'm going to do Timing Belt, water pump, tensioners and all front oil seals (including VVTI pulley) soon so stay tuned for video of that.

Even though it didn't fix my problem, if your engine is wet from top to bottom, it's very likely that only valve cover gasket is leaking so it's definitely worth changing it out (it's super easy to do too).

NOTE: Be careful when tightening valve covers as they are soft and easily break! A lot of people break them when changing gasket.
Toyota recommends putting RTV gasket maker on corners of gasket but I've put it on whole front and back side, just in case. Also remember, to re-tight valve cover every once in a while.
