1988 4runner,22R-E. Ive bin trying to figure out where all i have to block off for my EGR.Where else besides the holes on the top of my manifold where the the copper EGR rail is?

I found these, ill probably make my own based on these though

I know you have to block right her,in this case at the top of the header, but ive read stuff about blocking something on the intake or?

EWAYota

Just leave your EGR on. No need to block it off, just disconnect it and put vacuum caps on everything that you've disconnected.

Theres one or two caps off the intake if my memory is correct. I can take some more pictures tomorrow if you need.

Justinvd

That would be awsome if you could do that. Im gonna have to paint mine up like that one of these days too . Thank you very much for the help

EWAYota

Batteries died on the camera today, I'll get some tomorrow.

Justinvd

Thats no problem i can wait, any help is awsome

EWAYota

hehe, got the photos, now its just depending on when I find the usb cord for the camera-computer connection.

I have tomorrow off so I should be able to scrounge it up. Sad that I have 2 of them and can't find a single one.

Justinvd

Right on, thanks for going way outa your way

5 Vacuum caps:


1 Vacuum Cap:


Left Side, bottom of intake chamber, 1 vacuum cap:


This might have been two hoses???? Condensed to one:


All the connectors from what was on top of valve cover:


Disconnected EGR wire:


And I do believe thats it.....

Maybe this was capped before or after, can't remember since it doesn't look like a cap I bought:

Justinvd

Thank you very much for the help, im gona start on this right away

how does the engine perform with all those hoses blocked?

The bottom picture with the black plastic cap is normally capped.

I haven't had any negative effects from it, minus the CEL staying on

joshuapc

what about all those metal tubings that the hoses connect to located on the passenger side of the valve cover?

EWAYota

I think your referring to the air rail (i'm sure there's an actual name for it)? The air rail is attached between the intake chamber and the head. You can remove the air rail if you chose too. You'd have to remove the intake chamber from the head though, so that's up to you. I removed mine just because I did all this when I had the head off.

joshuapc

how does the engine perform without all that tubing and hoses?

EWAYota

Just fine, maybe even a little better. I did mine due to lack of money to purchase a new EGR valve, haven't had an issue yet.

get a 10k resistor and solder it across the egr terminals and reset efi cpu and viola no more cel

EWAYota

Thats a good idea, but I've gotten to the point that I don't notice it much anymore.

What's the purpose of this hose....or the two hoses, rather....going to the distributor? And, is that and all those little hoses you blocked off w/caps on the TB and intake only for the EGR system?

BTW, that's lovely blue your motor is wearing. Is that Ralph Lauren?
