Wow...you can read wikipedia. I'm impressed ret1614.

(BTW..wikipedia is notorious for giving out inaccurate info - so I wouldn't recommend believing everything you read there as being handed to you on a stone tablet after listening to a talking burning bush...lol)

I only paraphrased them (and other stuff I have studied in the past) and borrowed a few lines of theirs (with the necessary corrections) to make my point. And because I admit...I was just too lazy to type it all out myself.

My point was that the stock emissions equipment on most Luvs is shot and doesn't work worth a darn even if it isn't. Besides...there hasn't been any 100+ octane or leaded gas available commercially at the pump anywhere in the USA for a very long time, and a lot of areas not only just have low octane fuel available cheap - but a lot of it has alcohol mixed into it that doesn't get along with most of that 70's era emissions gear very well at all either.

So if your lucky enough that you don't need to pass smog where you live, you have the option available to you to remove it all, upgrade your engine, and end up with better performance, better hp/torque, better gas mileage, lower emissions, and less worthless stuff in the way under the hood. If not - then you need to find out precisely just what you can or can't change before you invest money and time in just getting yourself into a messy debate with your local smog certifying authority.

Ultimately though..the choice is for each Luv owner to make for themselves. And ret1614, as much as love talking about these old trucks, I really don't want to get into a nit-picking or hair -splitting contest about the value(?) or efficiency(?) of a stock mid-to-late late 70's Chevy Luv's EGR valve...so I'm officially done with this thread...lol

Besides...wtf do I know? I just read Playboy for the articles...lol

a little curious as to why the fittings are not just replaced with set screws or bolts? but i am new to luvs and emmisions equipment in genral (drove 69 chevy since 12). lots of good info. found the threads to be 14mmx1.25 on the other thread so i plan to plug the block screws with set screws. also, while eveybody is about to bear arms, will i notice a big driving issue taking the egr off with a STOCK moter. was said that a modified one will show no issues, but for now i just need to get her running and pull all the bull sh/& while i have it apart. thanks

lol, it's all good. Wasn't trying to bust on ya taz, it just seemed to me that you were putting a spin on everything... true, there hasn't been 100+ at the pump since the 60's I think, something to do with catalytic converters.
Oh, and I only quoted Wikipedia because you did (trust me, I know the pitfalls of wikipedia). I've been training to get my smog cert. for about a year and a half now, so the rest of that was from my own head.


There's a slight chance that it will have an exhaust leak at the place where the EGR tube goes into the exhaust manifold, so maybe a copper sealing washer or some kind of sealant on the pipe plug.

You might notice a preformance change, depending on the condition of your EGR (if it's dead, things will get better, if it's working, things might get worse, depending on how you drive it). It's mostly for highway driving, so if it's your around town vehicle, it won't make much difference.

It's been my experience. after hanging around here for over 6 years, that those that live in smog certification free areas that really love their trucks and intend on keeping them for a long time usually do some type of upgrade/customization to them, from mild to wild.

(And the ones that don't...they most likely will also try their best to do what they can.)

A lot of those that choose to keep a 4 banger engine under the hood also usually wind up de-smogging them and doing a major upgrade to the engine and drivetrain to get more hp/torque, better fuel economy, and better handling than the stock 75 hp/4 speed package that they came with from the factory can deliver. 4X4 Luvs are a bit more difficult to upgrade - but still not impossible. If done properly, it can (and usually does) result in lower emissions than the outdated stock emissions original equipment that came with their truck was capable of producing.

Fortunately for us all, thanks to Ben and his staff, this site exists to help guide everyone with it's huge wealth of free available info, it's many members that have owned a lot of these trucks for a long time, and the large number of members here that have a great volume of technical knowledge on the subject. Many auto/truck fans and websites are not so fortunate.

I never intended to growl at you personally ret1614...and if it came across like that I humbly apologize. But as a school- trained former certified auto technician that's been customizing old Chevy cars/trucks for over 30 years, it's been my experience that the gov't usually has way more rules than it has common sense when it comes to mods on older vehicles.

So no problem. Good luck on getting your certification. At least there might be one guy some day that actually has access to enough accurate info and that actually owns a Luv doing the smog testing somewhere. IMHO...that darn near qualifies you as an endangered species....lol

LOL...... smog sucks.

Sure does. But in CA, if you've got a smog cert, you have a job for as long as you want one.

Well, I got to looking at the wiring diagram, and the series 9-10 LUV has a thermostatically controlled EGR... But, from the way things look, series four trucks ('75) have the control valve, but it's not hooked up in a way that's gonna really work very well... plus, that's only on the California spenc trucks, and it runs on a timer it looks like. lol, that's pretty worthless, and the guys with these trucks look like they've got a bit to gain with the removal of the EGR.

Be careful if you live in Houston and will need to have your truck inspected. They check that stuff out. I had a 78 Ford 3/4 Ton Van with a 460 HD Trailer Package, they were trying to find some vacuum hose spec's for it, but could not find them, so they had to pass it. It was regular leaded gas engine due to the size. They came to me with that stuff. I didn't live in Houston but just stopped at one of those inspection places. I am not sure if they do a tail pipe check or not on that old of a car. I had a friend that lived in Dallas and his VW Scirocco would not pass the tail pipe test. I am not sure of the year but it was only sold it till '88. He put some thing in the gas that made it pass. I think it was running mostly that stuff. He bought it at a FLAPS. he sent all of us the before and after tail pipe tests.

My sister lives up in the country out side of Harris county and the zone for the strict checks. Her check engine light has been on since she bought her Van... That would not pass in Houston...

If you do not live there you can get most things a sticker. My old 85 GMC with a 350, headers and no smog stuff I could get passed with no problem.. And it was Canadian truck too, it still had the KM/H only speedometer in it.

If you have a Houston address on your title, or insurance card, you have to get it inspected in Houston. Ask hotrod80 or CTluv if they have any problems with their V8 Luvs getting a sticker on them. I could be wrong on all of that too.

lol, after OBDII (1995 I believe), the check engine light only comes on for something that would cause the vehicle to not pass smog... so that van shouldn't pass smog anywhere. That's the first thing they look at... no machines or testing equipment necessary, just a minimum of one eyeball...

so forgive me for being simple mined. but. so removing the egr is not a good thing but we can remove everything else? or it does not matter if we remove it or not.

It really depends on where you live. In your state you need to see what the Calli guys say. It may take some performance away, but I think the most is from turning the smog pump.

Like PapaG said...what you can or can't do legally is controlled by the smog certification rules and laws in your area.

Anybody that lives near where he does care to help him out?

I have a Smog cert, it is not worth much since most places dont make much on this service. I have had it for over 10 years and never made a living with it.

I do live in cali but i dont have any need for the smog stuff. I just want to clean up the engine bay. and one of my trucks is a 1975 so smoging is not a issue for me. but reading what was posted made me question wheather to leave the EGR on, if it will cost me performance down the road. the other problem for me was the charcoal canister and what to plug and if I need a fuel return line. and was woundering if my fuel milage will decrease when the canister is removed. but its probably not even noticable, right?

Huh. Almost every smog inspection station that I've ever seen has been doing brisk enough business to buy drive on dynos (but you've gotta be good to work at one of those shops). They do require bi-annual smog checks in Camarillo. lol, is everything new down there or what?

Well, by the way things look, take the one off of your '75, and leave it on your '79. Taz is right, the mid '70s EGRs aren't worth beans. They just aren't hooked up in a way so as to be very beneficial. The evap box on the driver's side in the bed is there to catch the gas that evaporates out of the carburetor, so remove it or not, it doesn't use any power, so it's just gonna be the work to take it off. Do you live in Kern County?

These are pretty helpful:

This truck looks amazing, and all the smog is intact:

lol, but what can I say... the only working piece of smog equipment on my truck is the EGR. Stuff wears out, and my g-pa (second owner) cut the cat out of it.
