VVTi Pulley - Oil Leak!!

murarie...
Did you ever get to resolve the oil leak issue?
I have the same oil leak with 120k on my wife's GS300.
I'm looking at replacing the whole VVT-i pulley at about $160.

I would say only replace the VVT-i cam gear if it starts to leak like mine.
Very few would replace it as preventive maintenance.
But it might not be a bad idea to replace it sooner than later as our GS's get on in miles, things like this happen.
It will be at least a week or two before I get to replace the VVT-i cam gear, I'll also do the valve cover gaskets. I may also have to replace the timing belt as it may have been soaked in oil.
Someone more knowledgeable about the VVT-i cam gear please chime in. Is this part serviceable? Is the washer behind the 14mm hex bolt double as an oil seal?

ok, after looking at the FSM looks like I might just need a $0.75 seal washer, worth a try anyway...

Scope of the work
Well today I went out to pin point the leak to try to verify where the leak was coming from.
After removing the two top timing covers I had good access to the cam gears. Oil residue was apparent but not the origin.
So with the covers off I ran the motor, after a few seconds the origin of the leak was obvious, shown in the pic, at the tip of the screwdriver
Oil started to mist along the outer edge of the VVT-i pulley, shown in the pic, as a red line.
Now I know a new VVT-i pulley / intake cam gear. The timing belt appears to be oil free.

No more oil leaks
Yes, everything is good, oil stays inside the motor.
Here's a link to the write up I did on the job.
New valve cover gasket, cam seals and VVT-i pulley

I'm not so sure about the RTV in the VVT-i pulley. I have heard others say that it works fine. My personal experience wasn't so good. It still leaked. I ended up getting the Viton O-ring from Jeff and it worked just fine.
I agree - 5 years!!!!! lol.

Function. First time I did this I realized I had to have filled the channels. Took it off, sure enough, was totally filled in, lol glad I said screw it man better check now, not after.. I would have been trying to figure that out for god knows how long. Anyhow, did that to both cam seals and crank seal. Sat the seals in with a PVC pipe to push seal into place after tightening em up and all. Then again smeared some to the outside of the seals to prevent leak. Worked like a god dam charm that's all I gotta say. Just remember, you don't have to apply it at all, I just chose to, so I also was VERY reserved on how much I used. I've got a video actually showing me do it for anyone who wanted to see back when... Thanks again to Jeff for that oring! Either that or the FIPG did it! Lol I'll never know! (Good thing)
