Finally have some decent weather and am going to start with a good servicing changing fluids, plugs/wires, filters etc. Then I need to source some CA emissions equipment. I have some of the pieces, but the previous owner removed everything and I am missing a lot of hardware and misc. pieces. Ill post pics of the parts I have and maybe you guys can help me make since of things. Or if some one has any spare or emissions parts they no longer need shoot me a pm.Thanks for any help and interest. Site seems to have a lot of good members and has proved to be a valuable source of information so far

Once its smogged and a strong runner, that is exactly where my money is heading. Starting with the bench seat, the spring poking me in the back for the hour and a half drive home after purchasing quickly had made restoring the bench seat a top priority when it comes to the interior. Thanks for the interest

Welcome to Ratsun. That is a nice looking truck, especially for less than a grand.

 

This guy was looking at removing smog stuff from his truck, maybe he will let it go. I have no idea if the parts interchange from his 76? to your 79 though.

Thanks for the Welcome, and the lead on possible smog parts. Definitely appreciate that

Well unfortunately progress has been super slow. I had a hell of time finding the necessary smog parts, but the good news is that I finally sourced all the needed parts. So here is what I have been up to.

I have cleaned, and painted all the parts that will be going on. They were taken down to bare metal, primer and high temp enamel paint. New K&N air filter and a NOS smog pump filter. The C.A.C. valve was ridiculously hard to find. I eventually located it at my local pick n pull. After months of nothing they got two 620's 5 days apart. So I am happy I finally have all the smog parts, but have some other issues to take care of before they can go on.

The previous owner, had capped the air injection system, and in doing so bent the shit out of the metal pipe that attaches to the air check valve, putting a hole through the metal. We got the cap off, then repaired the pipe with some JB weld, split a section of heater hose wrapped it around the pipe the hose clamped it in place. Thing is solid as a rock.

I am happy with the repair, as long as it holds up it should be just fine.

With the Air injection system fixed, and no longer leaking we began to make repairs to the cooling system. We cut out a section of crimped metal coolant lines and repaired it with new high temp rubber hose.

We also replaced a section of rubber coolant line that was kinked do to it being too long. By repairing both these I am sure the cooling system will function better.

Installed new upper and lower radiator hoses, cap, and a new thermostat.

While we were at it went ahead and put on new NGK plugs and wires.

I took of my EGR valve and the tube is completely carbon fouled, I mean clogged to the top with brown carbon deposits. Getting the egr tube off looks like a pain, anyone have any advice or suggestions of how to remove or clean this out?

 

 

I also am looking for some help routing the lines to my carbon canister. In particular I need to know what connects to this red capped inlet?

Thanks for the kind words Pharouh. This smog stuff can be ridiculously confusing.

 

Got some time today to work on my truck, changed oil and oil filter. Adjusted idle speed, and further attempted to clean the EGR tube. PROGRESS, I now have air flow through the EGR tube. Its not much but its there. There is good suction on the the back hole(closest to the firewall) which I believe leads to the intake manifold, but the front hole there is not much pressure. I had to cover everything up though as we are supposed to have rain for the next week or so. Things are gonna be put on hold until then, but I am gonna try one more time to clean things out better and then go ahead and bolt everything on. If all goes well I should be able to schedule a smog check after that.
