What is this part? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Need help figuring out the name and part number of this part. Came off the driver side of the engine. The seal is melted and is leaking oil.

It looks to be a camshaft position sensor.

Describe the position on the engine and the person at the parts department will know what to look for.

Part Number: 10921AA231

Vvt control solenoid. It's not a sensor.

Your solenoid is probably fine, you just need a new o ring for it.

Yeah I know the solenoid is fine. Just needed to find which part it was so I could find a new O-ring.

Although not a valve. All manufacturer's tech docs refer to it as an oil control valve, or 'OCV.'

Clipped, not melted. As in installed incorrectly.

It’s a magnet the runs in and out to control the timing adjustment.

I'm slightly annoyed that more and more makers are using this style of VVT solenoid. I don't like them.

Sure, they simplify the head casting a lot, but I don't like how they rely on pushing a spinning valve with a stationary pin. Not as dumb as nissan eVTC "Hey let's retard the exhaust cam by dragging it against the timing cover with a clutch", but pretty dumb. But hey, maybe I'm just insane, they're pretty reliable on most makes, wear hasn't shown itself to be a problem and they're easy to service, so I can just shove my lunatic ramblings up my ash I guess...

something-something, recommended serviceable life... similar reasons they no longer intentionally overbuild motors like they did with the 2jz.

We have far less issues on the m156 linear style actuator than the magnets used on series engines.

Numbers in circulation are obviously skewed 1000% or more, but I’ve never had an issue with the AMG system. We were replacing magnets on m272 and m273’s daily a while back.

Microabrasions on the sealing surface of the actuation piston blah blah blah. At least they’re cheap, and labor on all 4 in the worst case scenario is only like 4 hours.

Opened the bulletin, “Scoring formation at the piston by dirt entry leads to stiffness/seizing of the solenoid plunger. The piston in the new camshaft adjustment solenoid has a nitrided surface to prevent seizing.“

These Subaru ones look downright easy to replace.

Strange, I've had to replace a bunch of linear actuator (lots on chevy ecotec, a few on chrysler world engines, a single on a toyota 5.7), but this style, not a single one so far, all brands combined, even including all the old and busted volkswagen CCTAs.
