EGR Valve block off

[22_450r]

Hey,

just bought a 03 f350 with 66k miles had no ficm but cranks. hoping the powerstruggle starts when I plug one in lol. But on to the real question, it has no egr valve in it either can I just put a plate where the valve goes and call it quits?

Thanks

Only if there is a ERG cooler delete kit already installed, or both ends of the EGR coolers are welded shut, or the up pipe side of the EGR cooler has a block off plate on it. With any of these methods, your gonna need to use a gasket with the valve blocker plate.

Well could I put just the top cover on to see if it runs, what would that do? I guess i really just don't understand what the valve does open/closed and what just covering it would do. Any info is appreciated.

Thanks

Exhaust gases leave the turbo thru the down pipe, the down pipe has a small pipe that connects to the back of the EGR cooler. Some of the exhaust gases pass thru the EGR cooler to the intake. These gases are cooled in the EGR cooler before they pass thru the EGR valve, then to the intake. The EGR valve gets commands from the PCM on when to open and close.

So if you just put a plate on where the EGR valve goes and don't block off the back of the EGR cooler at the down pipe, then you will have exhaust gases constantly pushed into the intake. NOT GOOD!

You could put a plate on the EGR valve, it will run like poop.

Close but no cigar Lilpooh. The exhaust gasses come to the egr cooler via the passenger side up pipe before the turbo.

Without the EGR valve you will be pumping all that exhaust into the intake like the EGR valve is full open. If it runs at all it'll run like $hit.

Dang!! I knew that, just got mixed up! LOL!!

Alright thanks guys

My valve is opened about 30% most of the time. But no flow through it anyway with EGR cooler out of the equasion.

And the relevance of your contribution to this thread and the OPs question is?..........
