Hi all. I am new to the site. I just drove home my first 6.2 in a 85 burb K10. The motor has 136k on it and runs great. I noticed the egr lines were all broken where they meet the air canister above the alternator. I removed both lines from the intake and plugged them. I then removed the hose coming from the oil fill and plugged it. With the exception of the EGR valve itself, is this all of the stuff I need to get rid of?
I have to track down 2 fuel leaks. One is at the front of the motor, One is at the rear.


Thanks for the help,
Travis

Welcome to the forum! :welcome: Sounds like you've got a nice rig there... :)

First of all, don't remove the hose that goes to the oil fill. That is part of the CDR (Crankcase Depression Regulator, sort of like the Positive Crankcase Ventilation system on a gasser) system and has nothing to do with the EGR. If you plug that hose and run the truck that way the crankcase pressure can skyrocket and blow out gaskets and seals on the engine. If you feel that you must unhook it, don't plug it, but I'll warn you that it will smell terrible.

I don't know what the lines by the alternator would be. The EGR/EPR control solenoids and all the lines associated with the EGR/EPR system are located on the driver's side on the back of the valve cover and go under the air cleaner/around the back of the engine from there. There are two solenoids, one for the EGR and one for the EPR. You need to disconnect and plug the hoses that go from there to disable the EGR/EPR... The one for the EGR valve goes under the air cleaner and the one for the EPR valve goes down to the exhaust manifolds.

Now if you want to eliminate the EGR you have to change the intake manifold to a J-code (non-EGR heavy-duty/military) manifold... Disconnecting it just makes it inoperable.

Hope this helps! :welcome:

The two lines on the intake that connect to the canister above the alternator are probably the crankcase vent lines. If so they are metal tubes attached to the canister (the CDR) by rubber hoses. The other ends of these metal tubes are attached to the intake niples with rubber hose. The purpose is to carry crankcase fumes to the intake to be burned. As HS2500 says you should re-install those lines.
