VVTi cam gear Viton O-rings.

I looked at Jeff's video on rebuilding the VVTi pulley. I am in the process of replacing my VTI pulley. I know the VVTI pulley can move as much as 30 degrees separately from the camshaft. I assume that the replacement VVTi pulley must be in the same position within this 30 degree range as the pulley it is replacing. How can this be done, especially if the old pulley has already been removed? Are there alignment marks. Or does it matter, since the timing of the pulley will be adjusted based on the position of the valves and feedback from the ECU. I appreciate any help.

It doesn't have to be in the same position. When you reinstall the new gear and timing belt, just make sure the marks on the cam gears line up and you're good to go. The internal mechanism will "reset/realign" to zero degrees once you turn the crank clockwise. Just follow the factory procedure to reinstall the timing belt.

You don't have to take the cam gear off or anything to seal it..all you need is some high heat silicone to fill the grooves on the edges of the gear and use muffler putty sealer on top the silicone to seal the gear!...I did it on my 2002 gs300 and never had a leak and its going on 5 months now..you just have to take off the top and middle plastic covers to expose the gear and belt assembly..I repeat there is no need to take the gear off the car you can seal it while its on there!

It does not work
I took mine apart to replace the O-ring but couldn't find the appropriate O-ring to use. Instead of the O-ring I used some some black Permatex RTV and bolted the pulley back together. Drove halfway across the country without any problem.
Some guy on my.is told me that he had used a Toyota O-ring with this part number to seal up the pulley. I've never tried it before so I can't tell you guys if this is true or not.

I am lucky enough to only be about an hour away from Jeff Tsai's shop. Took it to him and ended up having my vvti seal fixed and well as the cam seals replaced and it seems to have fixed all of my oil leak issues. When I bought my car they supposedly replaced timing belt along with new cam seals. I even received a receipt where they bought the parts an marked them as being replaced. However, once Jeff dug into it he found that one cam seal had been replaced and they messed up the metal around the area where the seal goes. The other cam seal was hard enough that he thinks it was the original with 185k miles on it. He cleaned up the messed up area and replaced both cam seals with OEM seals. His guess is that hey attempted to get out one of the cam seals, struggled with it, mess up the area around it and then just said forget about the other seal and send it out the door. Jeff definitely knows the GS300 in and out. I won't even mention the multiple Supras he had out in front of his shop.

Do you have pictures if the grooves? Where the silicone needs to go?
