EGR delete or disabling through software

Don't think they'll be any deleting of EGR You might could take control over that electronic EGR valve but what are you going to do with it You've got to be real careful with EGR because it they've planned the given internal combustion temperature shift around the use of the EGR so if you start deleting it that's going to go up to normal non EGR type temperatures you're going to need rings and things that can stand that which I don't think is in the two ZZ FXE but good luck with it.

 

Yup. But there’s no way around it. When the cars roll out of the factory with clean/functional EGR system, the engine runs as it should, with lower combustion chamber temperatures, all cylinders in balance. Gradually it clogs, and unevenly, till cylinder one in particular is overly hot, then two and so on.

In the absence of an effective fix from Toyota, it’s what you have to do.

 

The engine is burning oil. That's why you have this issue.
Replace the short block. Or complete remanufactured engine. It "should" have the latest
pistons and rings to remedy the weak oil rings....

 

The Car Care Nut says any new short blocks will have the revised pistons and rings.

 

I don’t “know” this but I’ve read the egr only opens when the cylinders are under vacuum, ie engine braking. At least that’s normal operation for most cars I think. Like I said prior this Prius is a whole new beast to me. I could be totally wrong.

I guess to be more clear on the first part, my thought was to pinch off the exhaust pipe feeding the egr - so no more exhaust.
Then have the input of the egr cooler open to the atmosphere - filtered of course.
So when the intake goes into vacuum the egr opens and sucks plain old filtered air into the manifold. Allowing the pistons to freely pump, no vacuum and no engine braking so my generator generates.
I suppose you wouldn’t really need the cooler at that point.
So the egr still functions normally, just sucking atmosphere instead of carbon.
Probably a bogus idea. Just late night pondering.

And it’s too late for piston rings, I put everything back together last night up to the intake/valve cover/egr, Torqued and sealed. Never noticed blue exhaust though…

 

Dang. Well. I put it mostly together last night.
It has new valve springs. And a head gasket kit
I Didn’t know the rings were that much of a problem. Compression test?

 

I feel like what you’re really telling me is to fix it up original style and then trade it in for a newer one with a post cat egr.

Cleaning it while frustrating wouldn’t be the worst thing ever with these type of gaskets but the idea of trying to blast all that build up through the intake valves into the cylinder makes me cringe.
I suppose you might manually rotate the engine till the valves are closed doing one set at a time…. As I type this I feel like someone is going to say duh thats what we recommended on page so and so.

 

Don't waste ur time arguing just block him like I did

 

Mercy me, after 3+ years I'd forgotten making that post!

 

Wherever you read that is a source you should probably rely less on.

EGR is used when the engine is producing power; it mixes the exhaust gas with the incoming air/fuel mixture. Mid-loads are where it is used; the EGR valve closes at low load (otherwise the idle would be rough), and closes at high load (otherwise it would limit the engine's max power).

At those moderate loads, it does reduce the engine's power a little—which is ok because it matches the moderate load—and is a more efficient way of doing that than having to close the throttle further and pump across it.
