EGR Cleaning: What did I get myself into?

Hard to tell in the egr inlet ports how bad it is.

So how clogged was it?

 

Easy access .

Excellent time to replace .

 

Damn, @Bay Stater had a busy day, he didn’t need no meet ups to work on his Prius @Raytheeagle

 

But think how much faster it can go with more hands available.

When and where are we “randomly” meeting again ?

 

Lol, you don’t want more than 1 hand on the vehicle, especially if theres nuts and bolts are involved because you might misplace it or accidentally install it in the wrong spot... it happens.

 

A good labeling and can system helps.

The key is communication .

 

Yeah be sure to run pipe cleaner, thin bottle brush or what have you, through these passages, the EGR "capillaries", plus the main EGR gallery. I tried in vain to get it spotless, finally settled for functionally clean.

 

No need for spotless.

You’ll go back in eventually, so good enough for now works.

 

With the EGR cooler and oxiclean I got to spotless, but it's stainless steel. The intake manifold is shite, porous plastic, not happening.

 

If you’ve determined where you’re putting your OCC and it won’t impede access to anything, I’d install.

You’ll need the intake manifold on before the egr pipe is installed, so that’s the only order of operation important though.

Good luck through your project .

 

You mean the air intake, air filter box. I would leave it off till you're done with the egr: IIRC you need to remove the EGR pipe, and the air box needs to be out of the way for that? Doesn't hurt to leave everything off.

 

Looking good.
