EGR Blocking on a 603
Well, after reading the fabulous posts on the site about the EGR blocking kit, I went ahead and fabricated my plate. It looked great and everything but something dawned on me as I was blocking the exhaust manifold!
Why block the exhaust manifold at all!? Couldnt you just put a blocker plate in between the intake and the EGR and then have everything else hooked up!? Even if the EGR opened, it would still block the flow of exhaust. I decided to just block the EGR intake and leave everything else hooked up...as I see it, it will do the same thing and the average person looking at the engine (including the emissions tester) wont know its disconnected. If this is a mistake, lemme know ASAP! Putty |

Absolutely right! Only reason to actually remove the hardware is to reduce weight and make maintenance in that area easier plus removal of the vacuum lines leaves one less place for a leak to start.

That's how I do it. If someone tells you it's a mistake, please let me know

I just removed the vacuum line coming off of the vacuum pump, but left all the rest. Looks factory unless you know what you're looking for

I can't confirm that the EGR valve isn't leaking. By blocking the mixing pipe port, I don't care if it's leaking. Same with removing altogether.

I had mine that way for years. Even left the vacuum line hooked up to the EGR so it worked. Than I got tired of extra vacuum parts because they can leak, and I wanted to de clutter the engine compartment as much as possible. So I put a plate over the manifold, and threw the valve along with all the vacuum lines that deal with it and the ARV.
The guys that smog them have to pop the hood to count the cylinders so I'm not to worried they are going to figure it out. Besides I only have to go through once or twice more, once it hits 25 years its smog exempt.

Well, perhaps I should clarify...I didnt leave the vacuum lines hooked up but looking at the threads, the valves were left off altogether. When I started blocking the exhaust manifold I realized that you will get a more foolproof seal just blocking the intake and leaving the other pipes on (except the vacuum line).
Driving the car for a couple days, I dont see any hindrance to doing it this way. |

The only reason to remove the valve is to clean up the engine room, you can leave it on it won't bother anything.

On the 300SD a quarter worked fine to block the mising port. I just pulled the valvr, put in in my 25cents and put the valve back on. I simply disconnected the vacuum line in the SDL. If I get ambitious, I will pull the valve and see what could be used to block the port.
