Cam Gear Rebuild Kit Compatible for Toyota Supra Lexus GS300 IS300 SC300 2JZ 1JZ VVTI

I love how a "rebuild" means a new o-ring and sealing washer...The VVTi sprocket relies on an o-ring. It gets hard over time and will leak. Knocking the cam bolt loose with an impact so you can remove the sprocket so you can replace the cam seal will almost certainly cause the sprocket to leak if it isn't already - so "rebuilding" the sprocket is mandatory.Toyota says not to pull the sprocket apart but that's BS. It's easy. Just remove the screws, pull it apart, scrape off the old crusty o-ring, replace it; and slap it back together. You basically can't do it wrong. The original installation of the screws creates a bit of a dent in the hub - so it'll fall back into it's original position when you reassemble.Also included is a new sealing washer for the underside of the head of the cam bolt. It's actually called a stat-o-seal washer.Good luck out there and keep that JZ alive - they'll never build anything that good ever again unless there's a world revolution by thinking people - which doesn't seem likely...

I have an older Lexus GS300 with the 2JZ engine. I love the car, and that 2JZ engine is probably one of the best ever made. You certainly don't see inline sixes anymore, but they are extremely well balanced, and with proper maintenance, next to impossible to ruin. The 2JZ however has a couple of quirks, including the gasket for the Cam gear that tends to harden with time, and result in minor oil leaks. This is a bit of a known issue, but not something terribly uncommon for a car that is 20 years old. It just so happens that rubber tends to harden overtime, so I don't blame the engine. I don't have this oil leak yet thankfully, but I will be getting my timing belt changed in the near future, and figure that as a good time to do a little preventative maintenance to the Cam gear. I've got a very good idea what the OEM part looks like, and this replacement kit is identical. I suppose the real proof will be once it's installed, but my initial impressions are very good in reference to the quality. All in all, it's a very inexpensive bit of preventative maintenance that you could do, especially if you are changing the timing belt soon. I'd recommend it.
