EGR Valve

Emissions are a big PITA. I just put a cat on it, and now need to put a new EGR on her. thing is its 110 buck CAD!!! I only spent 400 on the whole truck! Now, what do i do here? should I be able to get one cheaper? I dont think I'm gonan buy any more vehicles that need emissions stuff unless there are mid 90s and newer! Sniffer test just costs more...

What year is it and what part do you need? I can see if there is something in the local wrecking yard here...

It must suck to have emissions testings over there.. We don't have them here, yet. I'm smogging my TPI so that I won't be in any trouble when emissions testings make their way out here to Alberta

What makes you so sure the EGR is bad? Clogged up passages from running too rich is actually more common then a "Bad" EGR.

Many of those EGRs are a Bleed off style and you cannot test them with a hand vac pump. To verify if its working stick your finger against the diaphram and rev the engine up to about 2500RPM and hold it and see if you feel it open. If the holes are to small in the underside of the diaphram housing you can put a stick in the hole against the diaphram and feel the stick move when it opens. If the holes in the underside are large (most are) you can manual open the diaphram with your fingers. At idle if you open it it should cause the idle to go to hell. Its hot might need gloves.

If no change then its proably clogged up ports. Peice of coat hanger and a shop vac WITH THE CARB OFF THE ENGINE (you can suck gas up if the carb is still on and make a large boom and Darwin yourself) usualy does the trick. Will have to pull the carb off to clean the port in the plennum divider. Thats where my 79 plugged up.

They are supposed to start emissions testing here in '06 & I hate it to death. I think my '70 is grandfathered in (I would hope so, even California gives you that), but I'm gonna have to go out a buy a catalytic converter for my S-10.

You know, with today's modern technologies, we could probably bump up fuel mileage at least a good 25% if we got rid of all this emissions crap. Catch 22.

Thank you. You just made my point. If im not mistaken, we will run outta petroleum in this century. So why kill gas mileage with cats and emissions when we can clean the air? We can't exactly make petroleum
ALTHOUGH every internal combustion engine can easily be converted to burn hydrogen, which is the answer to the fossil feul probelm.
