Removed all the vac lines to the EGR, plugged both connections, my transmission shifts MUCH smoother than before, I can slam down the gas and not feel like the trans is going to fall out when it shifts from first to second.

Ok EGR and ARV disabling experts out there, please tell me how to disable both of these on my 1985 (Federal) 300D. I have been having this whistling for quite some time right after upshifts and have determined that it must be the ARV. I'm tired of hearing this. Do I have to install a blocking plate on the EGR, or is there another way? I guess I need a step-by-step procedure, since I'm a newbie to these modifications. I thank you, in advance, for your advice/tips.

Thanks,

Ken

Put a BB or other blockage in the vacuum tubes to each.

Now where exactly do these BB's go? I am going to lose some later this week on the wagon.

After 4,004 posts, you honestly think I believe you haven't seen a thread or two (thousand) about the EGR and ARV?

ForcedInduction, I only have 43 posts, so does that mean I get another question?

Ok, so a BB in both vacuum lines to each. Why do I read posts of a blocking plate for the EGR? Is that a better way, or another way?

Thanks,

Ken

BB's in the vacuum lines will disable their function. A blocking plate will completely block any exhaust flow if it leaks or it will allow you to completely remove it from the engine. They both work but the block off plate will really clean up the appearance of the engine and simplify the vacuum system.

Either will improve the performance and economy of the engine at the expense of an absurdly small increase in NOx emissions.

See THIS attachment for what the EGR and ARV look like.

ARV and surge

I always thought an air recirculation valve was designed primarily to prevent surge. Of course it may be that there is never enough boost on a stock engine to cause surge, but no one seems to have mentioned that function of the ARV in this thread.
