sorry forgot to add, yes, you are correct, once the car is 20 years old it no longer requires etesting. You can pull every bit of smog equipment of it and enjoy yourself.
Which is ballz because because there's virtually no difference (from an emissions point of view) in our cars from '87 to '91. But because some yahoo at the ministry decided '87 "sounds good", the rest of us get the shaft! |

Check the restrictions on "hot rod" - in Maryland, we have the Street Rod category, which exempts you from emissions testing, BUT - you're limited on the number of miles you can drive per year, and where you can drive it (ie, shows, parades, other events). Do they enforce that? No idea... but the option is there for them to.
[RICHR] There are no restrictions for 'Hot Rod" but there are restrictions for "Historic" or "Classic" vehicles. As a "Historic" vehicle, you are exempt from emissions testing, but much like Maryland, you are supposed to only use the car for parades, and shows, and very limited driving. So following that logic, just as my car reaches the point when it's exempt from emissions testing, it'll be treated like a geriatic by our government. Nice. Maybe I can get the Ministry to issue the car a Senior Citizen certificate so I can get a discount when I renew the registration ever two years! |

Ok, I'm from Ontario also and have another thread going here regarding the EGR and emissions testing as I have just failed nox.

If your throwing a code doesn't mean your egr isn't working, however, it may not be.
If you scroll back through this thread (I believe it's on the first page) forum member Agent 86 was kind enough to post the diagnostic test for checking the entire EGR circuit.

Now, you have a number of options here. Yes by law you still have to have it tested because of the age of your car.
option1: have the egr cleaned or replaced. option2: cheat. Run your tank down to 1/4 and drop 2 litres of gas line antifreeze in it (make sure its one with a high concentrate of isopropl alcohol (purchase at canadian tire) and have it tested. Make sure the cats are hot. It will pass. option3: Get an estimate to repair your car over 600 dollars. Go to DOT and you will get a conditional pass for the car. You don't need to get it repaired ( this is a canadian glitch in the system). This is your last etest for the car so your homefree. By the way, you can do this every time each and every two years and never repair the car. When I failed last year, the technician testing the car (a very experienced GM mechanic) suggested setting the ignition timing to zero (0) and retesting the car. At that time, the car was so close to passing that he said it would have passed easily if I had zeroed the timing (just for the test, obviously). Probably true, however I didn't want to do that. The fact it was failing signalled a serious problem and I'd rather fix the problem then mask it, which is what I did. My current problem with the car throwing a code probably has a simple solution (like I said, either a vaccum leak or the EGR diagnostic switch - both inexpensive repairs to make), but it's begged the question of whether or not these cars could pass emissions if the EGR was removed and the chip was retuned to account for it's absense. GM has discontinued the EGR solenoid, so if that fails on any of our cars we're screwed with respect to emissions (unless you find one at a wrecker or used). Plus, with a lot of eary C4 owners looking for more power - coupled with the fact that the Super-Ram is no longer available - the Mini-Ram is becoming a poplular upgrade. The Mini-Ram doesn't have provisions for an EGR, so in Ontario if may be impossible to ever use one if you can't reprogram the computer to allow the car to pass the e-test without the EGR.

I haven't gotten an estimate to replace my EGR yet but I'm told its a couple hundred bucks:(

Do you recall whether the egr valve was a Delco of some other after market. I replace one in my 90. It was an aftermarket and as I found out the wrong type (positive vs. negative back pressure). (check some of the other threads on this site) Additionally, I got a 92 solinoid and adapted it to work for my car. The difference is in mounting and hose connection but nothing major.

But your idea of adapting a '92 solenoid sounds good. I just ordered up a new EGR diagnostic switch today (should be here tomorrow), but if I need the solenoid, I may try your idea. Thanks! :cheers: |

According to the new rules on the Drive Clean webwsite, that holds true only if it's 1987 and older. 1988 and new cars will still need to be emissions tested every two years 'til they are 30 years old.

I'm looking at swapping out the valve myself. On my 92 lt1 car, the EGR is at the back of the engine at the top held on by two very visable bolts. Its a 6 speed car. I found out that the two different valve listings are for an auto or a manual trans.
Is that all there is to it? From what it looks like I won't have to remove anything except the left side plastic valve cover to get at it. If its that simple I'll do it myself. Comments? |

wow, I'll have to check that one out. I was under the understanding that it advanced every year so my 93 would not need one after 5 more years or two more tests.
Personally, I urge every Ontarian to write the ministry regarding this.

I've never replaced the EGR valve on an LT1 but I'm sure it's easier than on the L98. You don't have to deal with removing the plenum and/or runners. It's just two bolts that hold it place and a single vacuum line that runs to the diaphram housing. That's it. For the effort, I'd definitely do it myself. Hopefully one or more of the forum's LT1 owners can add their comments on this though... |
your dead right. Its really easy as long as I don't drop a bolt. I'm going to order the part tomorrow. Its 94 bucks at Part source.

I had a bad EGR reading on my Chrysler Sebring and I cleaned it by squirting carb cleaner in it and getting a lot of carbon out of it. I could work the plunger with my finger and once it was all clean, the car ran great and no more codes.
|
That was pretty easy. A tight fit but a few rags underneath and an extra set of hands holding the valve in place while threading the inside bolt helps. I cleaned the old valve out with carb cleaner. It was pretty grungy but the plunger was still operating manually.
Now we'll see how an Etest goes. |

Nope its a brand new one. Made in USA and not korea thank god lol. We shall see. I did clean the old one and will probably test it at a later date.
|
Well the car blew clean, it was the EGR valve. The old one I replaced would not hold vaccum at all. The other numbers went up and Nox went down. Tech says this is normal as the engine is recompensating for the new valve. He says next time it will blow even better:)
