Maybe deceased? Since a seized engine would technically be dead.

A "seized" engine could also be taken away from you!
No wonder people have a hard time learning English!

He actually could have meant ceased, as in ceased firing, thus not turning the crank and such. Yes, i know thats stretching it BUT IT STILL WORKS,

"Manufacture" is a bit of a misnomer when it comes to engines (or any assembled module for that matter) as they really just take the parts from many, many suppliers and assemble them. I don't know for sure but seriously doubt that the actually "make" many of the parts in the engine them selves.

I don't know what manufacturer you work for but that's not true in my case.

As far as part number changes go, don't read much into that. Part numbers change all the time. The vast majority of them are for supplier changes. The part number for the engine changing could be a tiny revision or maybe they added production at a different powertrain plant and the new number represents that plants production.

Ya my last employer that made parts for heavy trucks almost had a monopoly and the part numbers were all about 40 years old!

Jaden

And you somehow missed that his parts "preform" and are "pervious"?

Here in Europe regulations set to Euro6 from mid2014. California rules are more restrictive starting up 2016.
head and valve set-cylinder let me think near emissions rather than adding performance.
Maybe useful to see if MY2015 US emissions are the same or not of previous production

I've just checked it and it is under Euro5. The same holds for the emissions. Nothing changed.

By the way, one more change is the part number of the muffler. A coincidence?

Is this a part number change for Toyota or Subaru? I know if Toyota changes the part number there is a reason (and they'll have a supersede note for the old part number).

Where's Jeff Lange when I need him...

I did the check for Subaru. However, the part numbers also changed for Toyota. Following are some examples:

Valve, Intake
old SU003-00196
new SU003-04745

Valve, Exhaust
old SU003-00197
new SU003-04746

Camshaft, Intake, RH
old SU003-00180
new SU003-04741

Camshaft, Exhaust, RH
old SU003-00181
new SU003-04742

Head & Valve Set, Cylinder, RH
old SU003-00103
new SU003-04958

Muffler could be a new part number because the 2015 MY now has the bigger round exhaust tips instead of the small ovalish ones of the years prior

This is Pre-2015

Whereas these are the 2015 MY

acro · 03-13-2015, 04:04 PM

Very interesting. I wonder what if means

I understand what you say, but this doesn't justify to change the entire muffler. You need to change only the exhaust tips. In fact the tips are a separate part:

nikitopo · 03-13-2015, 06:14 PM

If it wasn't the muffler, I could say that it is just a supplier change. But now we have too many coincidences. It is like they are trying to improve the performance of the engine ...

Maybe a preparation for the next release?
