Hey guys,

I searched, and searched, and then searched some more on here, but cannot find any info on where my EGR valve is located. It's not on the front of the intake where it normally is, I can't see anything that looks like it on the back. In it's location where it should be on the front is just the hose coming out of the water pump. I already have the gasket for it, exact shape of an EGR valve, that I got it from the GM dealer who got the information from my VIN, it's a W code 4.3, so from everything I've read it has to have one. Any help would be appreciated.

Here's my VIN: 1GNCT18W32K109506

 

Did someone possibly block off? Should be right above that hose on the Lower intake Manifold (LIM).

 

It may not have an EGR. My 2002 Blazer was a non EGR engine from the factory.
If its not on the front of the intake then its a non EGR engine.


This is how my engine looked being a non EGR engine.



This how it looks if it has EGR

 

The how am I able to get a gasket for one with my VIN lol, it's the original engine in there. I know X code Blazer don't have them, but does this mean then some W codes don't have them either?

 

Im not sure why they sold you the gasket, but my blazer is also a vin W and was a factory Non-EGR.

 

Here's what my engine looks like:



If that's the case of me not having one, I'll just take it back and get a fuel filter instead, since I want to change the one on there.

 

Yep, thats a non-EGR engine.
