    2004 Prius, 395,000 Replacing timing chain.

    What sizes, width on mm are the two oil pump o-rings inside the timing chain cover near the water pump?

    Toyota will have a part no for those. Tracking that down will ensure proper size and rubber spec. The official Toyota USA parts site is pretty much hooped right now, due to a rework, but there are alternatives, and a dealership parts department is always an option.

    Thank you. I'm trying to track down part numbers for both o-rings.

    Just googled this:

    toyota usa parts site is terrible now

    first 3 results concur. I’ve heard complaints get no realistic response too, typical corporate (non)reaction.
