Can I spray egr cleaner into the air intake?

My mechanic wants to inject 'Seafoam' into a vacuum connection on the intake manifold. Apparently, this is common practice for cleaning other vehicle manifolds.

 

What's the "EGR cleaner"?

I would get going on what's described in the first two links in my signature. Basically take off the intake manifold (and throttle body), andd the EGR components. Clean all.

Again, is this London, Ontario, or The City? I think someone else was saying there's a London in the States as well.

 

Have you actually found "EGR cleaner" to spray in? That's not a thing I've seen on the shelf.

If you had some, I guess you could spray it in the intake if you wanted, but I'm pretty sure by the time it reached any of the EGR components, it would have been turned into ... exhaust.

 

??? There are several of those (and Parises, too).

 

As @ChapmanF said, spraying that in the intake isn't going to do anything, for the EGR components. It's gonna go through the air passages in the intake, then onto the combustion chamber, where it will combust. It will maybe clean the throttle body a bit.

 

I guess if it really says "EGR cleaner" on the tin, the maker must think there's some reason to believe it'll survive that.

Color me surprised....

 

Maybe for cleaning accessible or removed EGR components.

 

Let the og poster have his/her moment to spray the product in!!!

 

Valvoline makes an EGR cleaner EGR Cleaner

 

Since the EGR valve on a petrol engine is closed under all non-load conditions, I wonder how the cleaner would reach it. (the instructions for the Valvoline product is to spray it into the engine at 2000rpm)

It might help clean things when the system is disassembled.

First time around filled the cooler with brake cleaner, and let it soak. It got a bit out, but really not that effective. It took multiple hour soaks in a (somewhat caustic) concentrated Oxi-Clean Versatile Stain Remover to do the job. Spraying that EGR cleaner, which I'd suspect is somewhat like brake cleaner, or throttle body cleaner, into the intake? Wouldn't do a thing.
