oil leak? Pls help identify the plastic piece

[rainbowheart]

Hi folks,
I have a 2010 limited and juster noticed that when I start the engine, oil leaks from a plastic piece just underneath the belt. Please see photos. I assume it is engine oil since I also noticed that the engine oil is decreasing. Could anyone please help me identify what that piece of plastic is and perhaps advise on how to replace it? part number maybe?

The first photo shows from underneath viewing up (red oval)

The 2nd photo shows viewing from the top and the plastic piece is underneath the belt (not showing)

The 3rd photo shows the plastic piece (red oval) in relation to engine oil filter when viewing up from underneath the vehicle.

thanks!

I can't make out what that part even looks like from the blurry photos.

Here's a link (if you haven't tried looking yet) to some parts diagrams of the engine from a dealer's page... If you can find the part there, you can order it...

I'm not 100% on this but I think your timing cover is leaking.
From what I have read other places the 1GR-FE has this as a mildly common leak. Try and google "1GR-FE timing cover leak" and you should see pictures that look very similar to yours.

Thanks for your reply. I like to point out that the plastic piece is connecting a plastic hose to a metal hole. Sorry about the photo. Size limitations....

Looks like an oil pressure sending unit

Thank you, yes, it is "OIL PRESSURE SWITCH ASSEMBLY" from the repair manual, the part number is 835300E010 for anyone interested. ~$30 from NAPA. Leak is from the plastic.

I used the wrong keyword "pressure sensor" on the repair manual, could not find it!

Napa may have it, but I would still go o.e. and get it from toyota. Better built and will last longer
