Good egr flow. Only intake cleaning enough?

I wonder what folks are going to say I know on my 13 persona at 2:30-40 mileage the EGR was barely or mildly starting to show decent enough buildup to possibly affect the air flow I did not have a chance to check it I did not have tec stream at the time. And I just looked at it like a 20 or 21 Corolla yesterday at my buddy's shop and it has the same little intercooler on it for the EGR business it doesn't look exactly the same but it does it's like shaped a tiny bit differently but it is exactly the same purpose type part and I don't see a lot of hubbub over on the Corolla side about it so who knows. I know I've got one off that I'll send over to the machine shop and have it tanked and it'll come back whistle clean and then I've got a buddy that runs the radiator shop that does intercoolers all the time if it needs any kind of specialty work I can't imagine enlarging it or any of that stuff it's the cooling of the gas that's clogging it up that stuff needs to stay hot although our engine doesn't like it to go back in hot that's a catch 22 I guess

 

I’d get on it.

 

If no trouble codes then you can wait til it self destructs. The oil burning is stuck rings. Damage is already done. Most used engines come w an EGR mounted on the side that you will keep in place. A few have a good water pump that wasn't crushed during engine removal. Seems like they all come w intake manifold. For these reasons, and it's too lake to save this engine, I guess you could wait till the head gasket blows and just replace it all. Side note, engine oil burning destroys the Cat Converter. Alll these things are judgment calls and opinions are going to vary wildly.

 

Probably so for now, as far as EGR issues.

 

Assuming you will sell it at 100,000mi, no need to clean anything.

 

That value for overall flow stacks up very well next to freshly-cleaned systems on our EGR flow data thread.

The overall flow value is unable to tell you about possible unbalanced flow through clogged small passages in the manifold. Hence the recommendation to pull off just the manifold and visually check/clean those passages, and that is a far easier job that delving into the (still very well-flowing) EGR cooler.

With a flow value like that, I'd be content to keeping tabs on that number over time, and not invest a lot of time in the whole stem-to-stern nightmare job, unless I could really think of nothing else worth doing with my time this year.

 

May be quite rare unless consumption is humongous. In our household we’ve got 3 oil burners and Prius is not even the worst. All of them passed annual emissions test no problem. One of the cars soon have 300kkm on the clock
