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.

P1349 TOYOTA - Variable Valve Timing System Malfunction Bank 1
Possible causes
- Dirty or low engine oil
- Valve timing
- Oil control valve (15330-28020 Valve assy, camshaft timing oil control)
- Variable Valve Timing controller assembly
- Engine Control Module (ECM)
