ok heres the deal. I am putting a new motor in my 80 4x4, the motor came from the local wrecking yard and is out of a 79. The E.G.R. valve and all the doo-hickie vacume lines are still there, even the little ( I guess you would call it a dashpot vacume is still there. Its on the passenger side up by the head where if there was a mechcanical fuel pump would be if there was a mechanical fuel pump.) It looks like it went to the E.G.R. valve. Do any of you guys know where I can get a gander at a vacume line routing guide??? I would like to still use it because its still there. If not I will just plug everything up and TRY TO keep the oil clean and fresh, but that can get expensive!! I prefer to use a synthetic oil and as you all know that crap is rather expensive. I have looked in all my books and I can not find a vacume line routing guide!!! And what is that little vacume line out of the oil pan for??? Should I just plug everything up and not worry about it?? I dont have emission testing here in Idaho, so I am not worried about emissions. But like I said before, the stuff is there and is all in good shape, I would like to try to use it. ANY HELP WOULD GREATLY BE APPRECIATED!!!
Thanks

Well the one from the pan goes to the check and relief valve. Identified by 3 connections one to aircleaner one to vapor canister and other to crankcase.
If it doesn't snow to much here tonight I will look and see if I have dashpot on my truck. Only dashpot I can think of is the one for throttle linkage.

I bet the thing you are talking about says B P T somewhere on it, it is the back pressure transducer. It should have a line out the bottom that goes to a steel hard line coming out of the EGR valve's exhaust side. The rest is marked on it, it will have a port marked carb and one marked valve. The one to the carb actually goes to the thermal valve on the intake, and then to the carb.

Oh and yeah, I do have the vac routing commited to memory.

There was a post someone did here with pictures of the vac routing. Search for "vac routing diagram" or "vacuum diagram" or something like that, I would do it but I'm feeling lazy tonight.

thats me xl
brother b send me your email and i'll send them to you..

Do you have a smog test down there in Lewiston? If not take all those little 1/4" vacuum lines off except the one to the distributor and cap off the ports. I ran that way in Coeur d Alene with my '80 and had none of the problems when the little suckers were all hooked up.
