Is it worth saving? P0A0F code!

I hope that it is a good one and works good for you!

 

Given your engine is 145k I would not use any of those parts, but you might want to save your coolant pumps, egr parts and intake. Maybe save the injectors, maf and other sensors.

Otherwise I would install your JDM as is with fresh oil.

 

I would return the water pump unless it was purchased at a dealer. Too many counterfeits in oem packaging and the obvious aftermarket's are just as bad.

It's up to you but realize a clean jdm without oxidation could be a 2020 or 2021 gen3 engine in Japan.

 

A battered carpenter's square is not quite a "machinist's straight edge", that said it's probably pretty straight. I would maybe check it first, say on a sheet of float glass or similar, in a couple of directions. Is it by chance aluminum?

Does sound like a bent piston arm.

Here's the head and block flatness specs:

I am curious which egr valve came with your jdm engine? It has a number on the housing but I can't quite make it out.
There were at least two versions.

 

25620-37120 Latest version.

 

Yes, it's better than 25620-37110.
You can't tell when an engine was manufactured, but individual engine attachments can indicate that it's still "young and strong"

 

Yes it is a better egr valve which is not as likely to wear and stick open at low rpms or wide open throttle when the egr flow is shut off by the ecm.

At some point you may want to verify the ecm calibration id (software version) is the latest as well.

Ouch:


Just googling the part no I see some totally preposterous prices, too. Hopefully no one bites.

 

That revised valve has been out for years now and still PriusChat doesn't know what they changed, because nobody who has bought one has been willing to take the black part off and take pictures. Are you game?

 

Well I don't have one, there's that.

I did finally manage to remove the cap on mine (part no ending in "10"). A hammer-driven impact screw driver, helped, and having replacement screws on hand for just-in-case. I put those in, for next time.

But yeah, agree, it'd be good to find out what the differences are. It's readily evident it's taller, maybe a centimeter.

 

Toyota has a kit which includes gaskets for less than the valve itself. One online Toyota dealer has the kit for $143 US or $202 Canadian. Part of the TSB is the ecm update.
