6.2 EGR

[Dvldog 8793]

Howdy
My 84 3/4 ton chev 6.2 van has a EGR valve located in the intake. This is different than any 6.2 I've seen.(all military trucks) In my van it seems that someone has disconected it. The hole in the aircleaner housing is pluged with silicon and the port on the EGR isn't hooked up to anything. Can I find a differnt intake and switch it over? or can I simply remove it and plub up the holes?
Thanks in advance!

Its an easy conversion. I have done several. Just get a J series intake off ebay or another source. Make sure you get the dual plane intake so that everything will bolt up to it (CDR passages and what not). If you have the fuel filter that mounts to the back of the intake make note of how it mounts. The 82-83 models had a small secondary fuel filter that mounted to the back of the intake with bolts that attached horizontally. The 84+ had the bigger dual purpose filter (primary and secondary) fuel filter mounted to the back of the intake on the vans only. The fuel filter housing attached by bolts that screwed into the intake vertically. So the mounting pads beween intake just for the fuel filter housing were different, so you'll need the right one for your applications, unless you want to adapt. Besides the fuel filter things, its a direct bolt in. The intake manifold gaskets you will get (preferably fel-pro) will have metal inserts in them that will block off the exhaust passages in the heads. Just use the gaskets matched with your new intake and you're set. Make sure the vacuum line that would be feeding the egr is plugged well, as to keep from having a vacuum leak. I think the swap is well worth it, it seems to give the engine a little more air and burn a little cleaner, not necessarily more power, because you're using the same fuel calibration. Hope this helps..
