The oil control valve (OCV) for the VVTi on the 1AZ-FE is held on by a single bolt, 10mm I think, that is directly under the OCV.

Anyone recall how they got to that bolt? I took off the air cleaner and the OCV is about an inch below the valve cover gasket at the back, passenger side, but the bolt is in a difficult to place to get to with normal tools and normal sized hands. Any suggestions? Thanks.

In case someone reads this in the future, for a 2002 Rav4 . . .

I got the oil control valve out. A wobble extension or a crowfoot wrench might work, but I don't have those. There was a flange sticking out from the corner of the plastic intake manifold (passenger side, rear). I didn't see any purpose for this flange and it was a hindrance to getting to the OCV bolt with a 10mm socket wrench (1/4" drive) so I cut off about 2/3 the width. The soft plastic was easy to cut with a small hacksaw.

I also moved the wiring harness for the positive terminal of the battery, but that may not be necessary.
