2011 Prius at 225K - Valvetrain Pictures

[The Critic]

Currently at 225K miles.

These were the photos from 185K: https://bobistheoilguy.com/forums/threads/2011-prius-valve-cover-photos.304912/

From 185k-225K, it received an oil change every 5K using any 0W20 synthetic on sale and a Genuine Toyota filter.

Engine was partially disassembled to reseal the cam housing and timing cover.

Looks like you just want to show off your steady hand FIPG skills

Gotta love those 5K OCIs !

Negative. I will never win any awards for squeezing out straight lines. I’ve seen far better examples posted on this site.

 

[OVERKILL]

Looks great!

 

[slacktide_bitog]

Looks good

Interesting that you have to use FIPG around the whole valve cover. Usually it's just at sharp edges, and sometimes even none at all

 

[Thomas Campbell]

Very clean.

TC are those rollers over top the springs ?

If they are... They do look to be in exceptionally good shape.

It don't get much better than that!

Looks great!

That looks awesome!

Very clean and plenty of miles left on that engine.

Looks like you took apart a brand new engine! Looks great! That's also a very clean engine bay!

Not familiar with the Prius to know , ,are those the engine operating miles or total miles on the vehicles. [the oil change interval]

But the engine didn't run for those miles.
Is there any way on those cases to trach engine hrs/miles ?
The engine could have less than 50k

All the above being said I bought an 88 Camry with the 4 cylinder engine brand new and at around 90,000 miles I changed the head gasket because the head gasket was leaking coolant to the outside of the engine and I used M1 oil changed once a year with the mileage between 7.500 to 14,000 miles per year with the higher miles from driving to the main branch when I lived in San Bruno California to San Jose California using 280 and cruising at 75 to 80 mph and the head was clean. M1 is a great oil.

You're looking at the cylinder head without any camshafts or timing chain installed. The cam housing is sealed to the head using FIPG. The camshafts are installed into the cam housing, then the engine gets timed.

Valve cover gets sealed to the cam housing with a gasket and some FIPG in two areas.

Rockers over valve springs, yes.

yes it did. Engine is usually running, just at a reduced load compared to a gas-only vehicle.

I would change oil less often and pocket the money as I don't think there is any benefit from keeping the engine this clean. But that's just me. It sure looks good!

On a that generation Prius - yes it did run for at least the VAST majority of those miles. They can only go very short distances at very low speed on electric only.

FWIW the 21 Escape does track electric only miles and it can do a fair amount of electric only. They've come a long way.

OP - Engine looks good of course.
