Review on 🛠️ WYZBEN O-ring Seal Cam Gear Rebuild for Toyota Lexus GS300, IS300, SC300 – Stop Oil Leaks with 2JZ 1JZ 2JZGTE 2JZGE VVTI Solution by Mark Marcellus

I stretched the o-ring as instructed and it didn't stay stretched for more than a few seconds to fit the groove. I began to gradually become more aggressive in trying to get the ring in place. It started to tear, so I quickly put it back together before it shrank. Needless to say, the mechanism began to leak after a few hundred miles. Also, I believe that a real quality Viton should be light brown in color. This item was black. I have learned that there are many counterfeits of these o-rings, so the buyer should be careful.
