Changing an engine in a 2011. Too much for amateurs?

Careful what you read on the interwebs. I'm pretty sure Gen3 is model year (MY) 2010-2015.
They surely started manufacturing 2010 MY cars in calendar year 2009, and that could be the source of confusion.
Good luck with the project.

 

I always wondered that myself. Maybe someone else can explain.
But perhaps maybe it was released in Japan or other parts in 2009 MY?

 

Our "2010" was built in August 2009, and we purchased it "new" in November 2010. That's a straddle that can cause groin-pull...

 

Japan did sell 2009 as shown below.
It def has Gen 3 styling

2009 Prius

 

14 has new rings, 15 has new pistons, or vice versa

 

Yeah the vice versa: new pistons in 14, also rings in 15. It'd be nice to see some more 2014 and 2015 votes in my oil consumption poll:

3rd gen model year and oil consumption | PriusChat

 

seems odd that they would do the pistons first, then realize 'dang, we should have done the rings too'.

that's what always confuses me.

 

Continuous improvement .

 

Both the pistons and rings are problematic?

Too, I think the jury's out on these new-and-improved pistons and rings. To flog the dead horse some more: I would think replacing knackered pistons/rings with original part numbers would also work wonders.

Looks like no fresh votes in my poll (3rd gen oil consumption by model year, linked above).

 

Hey, I voted just after seeing your post from yesterday in this thread -- so ONE new vote.

 

unless polls are stickied, you have to trip over them

 

i just figure if your looking for a problem, and decide the pistons are it, you might look closely at the rings at the same time, not a year later

 

Good idea, I'll ask. Too, I can just bump it occasionally.

 

I cant vote as too owning a gen 3 both of mine are gen 2 but I have replaced two 2010 engines and one 2012 due too oil consumption issues and egr issues
