Transfer Case Actuator "O" Ring Seal - 1999 GS 300

[Billy Munchkin]

GS 300 1999-2005  VVT-i  2JZ Engine

Experiencing the common oil leak from the back of the Camshaft Cover Plate, which means Camshaft oil seals and the "O" ring sitting behind the Timing Sprocket. This "O" ring apparently is not listed at Lexus/Toyota Parts departments, telling me I have buy the whole timing sprocket which is not only a piece of engineering art, its damn expensive. But he did say you get the "O" ring with it.

The only one I can find is the only one that comes up that fits the GX470  Pt No. 90301-56009, can anyone please throw any light on this subject and will it fit.

Thanks
