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

Hi Graham and welcome to the LOC.

I also looked on the Toyota parts database and cannot find the O ring just the seals.

For what they cost I would order the part number you found and see if they fit.

I also have the contact details of a company that manufactures O rings who will make them to a custom size with the correct materials for the application.

The last ones I bought were the brake reservoir O ring for my 1982 Suzuki GSX250, I did have to buy 10 but resold the rest individually.

Hi Steve and thanks for the welcome.

I think you could be right, I can't see any reason why they would change the size for different models but you know how Lexus work to gain the maximum!

If you look on youtube, you will see them stretch the "O" ring slightly but don't reveal any part no.

I have looked at Barnwell "O" Ring Manufacturers in the UK but will probably end up buying this ring 90301-56009 £6.10 as you say give it a go.

Thanks again for your reply
