Re: Just Failed CA Smog. Now what?
 

I will make time to check out the SMOG station that is walking distance from my house to see what is required (they tested my other 2 DDs). I believe to get the temp pass I will have to transfer ownership and all and don't think I can try a SMOG test with my Hawaii title/no reg.

I just realized that you are only 45 mins away. It seems there are at least a 1/2 dozen ZR-1s within the area now. You guys ever get together?

Re: Just Failed CA Smog. Now what?
 

What is ECT?

I had a thread a while back debating whether to keep the '91 or "upgrade" to a '93-'95. Looks like I should add this as a point to the upgrade side.

Re: Just Failed CA Smog. Now what?
 

I didn't realize there are so many of us in the Bay Area now. :dancing Z51JEFF looked over my Z when I bought it, but not aware of any group get togethers. I'm certainly game though!

Re: Just Failed CA Smog. Now what?
 

If you can get the car on a trailer and get it to Fremont I can talk to somebody about doing a pretest. As far as a get together,I stopped trying to get people together,they just aren't interested.At one point I thought it would be great to get some ZR-1s together at one of the summer Good Guys shows.

Re: Just Failed CA Smog. Now what?
 

I had no idea either and have been so busy since moving to pay attention. It's a thought and if nothing else meet at a Cars and Coffee at the Blackhawk Automotive Museum later this year. This past summer I saw 3 Zs there and could not find the owners.:cheers:

Okay, I'll see what I can find out when I get ready and thanks for your thoughts and offer. My bad memory and maybe we already had this conversation. Look at WAZOO with over a dozen guys that meet regularly and pull motors or whatever together. Great bunch over there and just met up with two of them in Wash, D.C.; came out of their way by Metro to meet up.:cheers:

Re: Just Failed CA Smog. Now what?
 

The white-red 91 was mine. I just talked to Cliff -Dynamite- a few days ago about getting some Zs together, he's about 150 miles from but said he would be interested in getting some people together. Ca has the most ZR-1s so we really need show the Boys from Illinois that we can play too!

Re: Just Failed CA Smog. Now what?
 

Okay, I know Todd was there (Coupe89) too and there was a Black one with some heads in the hatch area, but parked on the far side parking lot.
I don't know if Steve Jasik frequents this site, but I know he is on the list server side and by you near San Jose. I don't know, the FBI and WAZOO have a tight group there. But no reason we can't have a NORCAL group. I am on the fence with putting down roots here and love it....so does the wife so that is half the battle.

Re: Just Failed CA Smog. Now what?
 

To be honest with you I'd really be interested in seeing what your car would do on the smog test with the mods you have.

Re: Just Failed CA Smog. Now what?
 

The owners were too busy look at other people cars :-D

Re: Just Failed CA Smog. Now what?
 

Ive only seen 3 ZR-1s at this Cars and Coffee GTG.One was a red 90 or 91 a black 91 that the guy that owns it hasn't got a clue as to what hes up against when he needs help with the injectors,didn't really want to have a conversation and another black car that was leaving when I was.For those in the area this thing is a mind blower.Where else can you find an original Ford G.T.40 parked next to some rusty,clapped out Rat Rod?

Re: Just Failed CA Smog. Now what?
 

My apologies to the OP for bringing up all kinds of other subjects to your post.

Thanks for the tips and tricks posted that will help me when the day comes and like Z51Jeff said, I am curious to know how far off I am to meet Cali sniffer.

Let's try to make an effort to meet later this year!

Craig :saluting:

Re: Just Failed CA Smog. Now what?
 

There are two difficulties for organizing ZR1 groups in CA......

Distance.....CA is 1,000 miles North to South and while you may have A ZR1 in CA the distance to another ZR1 also in CA is prohibitive for meeting up.

Emissions Issues make it next to impossible to Modify ZR1s in CA so those that like to "tinker" on the LT5 are rare in CA solely because of Emissions Requirements and Rules on Alterations to the Engine of any kind.

Just Saying :cheers:

In South Dakota there are also two issues.......Not Many ZR1s in South Dakota and the Winters Prohibit ZR1 Driving......And if you do not have a Heated Shed almost impossible to Modify a ZR1 during the Winter Months.

Just Saying :cheers:

Keep us posted Craig on the CA Emissions Situation :handshak:

Re: Just Failed CA Smog. Now what?
 

Totally understood and why I said NORCAL (Northern California) or Bay Area if I wanted better chances. As much as I would like to meet up with the guys in Southern California (like good ol Ted Feder, etc.), the drive would kill me these days unless I were leisurely touring on vacation. When I was younger....I could do it. Like when I moved to Connecticut from Hawaii and shipped my car to LA, drove to Florida (West Palm Beach) to visit a friend and then up to Connecticut to report in for duty a little over week later.

Yes, I am ready to give up and get a stock Z to live in CA so I can drive. I could not in another SMOG ruled country like Japan for 3 years with a big paperweight in the garage. Well, you already know the saga. Thanks for your wishes and thoughts.

Re: Just Failed CA Smog. Now what?
 

You can buy mine. It passes every time.

Re: Just Failed CA Smog. Now what?
 

Ok. I put front of the car up on race ramps and got under there to take a look. It looks like the sensors are pretty far back at the rear of the front tires. Not much room to work. Does the sensor use a 18mm wrench? My largest was 17mm, so I tried an adjustable wrench for now. The sensor is really tight in there! Any suggestions on how to loosen it or just get a 18mm wrench and use brute force?

Re: Just Failed CA Smog. Now what?
 

The sensors use a special wrench.

Re: Just Failed CA Smog. Now what?
 

What kind and size? Like the ones Coupe89 posted in this thread?

http://www.zr1.net/forum/showpost.ph...4&postcount=15

Re: Just Failed CA Smog. Now what?
 

Don't use an adjustable, 7/8 will fit or just go buy a muffler shop and have them change them.

Here is a photo of an O2 sensor socket, KD 3259 that should be available at your local auto parts. :cheers:

Re: Just Failed CA Smog. Now what?
 

There are some unbelievable deals these days on ZR-1s, but I would rather buy local that I know of passing "CA" emissions as well as save on the transportation costs. Thanks for the offer (if it was to me).

Re: Just Failed CA Smog. Now what?
 

I have both sockets. But the longer one did fit for me. Too tight of a space...
I used the one I pictured.

Re: Just Failed CA Smog. Now what?
 

May I ask where you purchased the socket on the left side of your picture of tools you used?

Any help much appreciated.

Gary

Re: Just Failed CA Smog. Now what?
 

I have the tool on the left and this is what I used on both sides.

Re: Just Failed CA Smog. Now what?
 

Welcome to Northeren Ca.

Yes having a ZR1 here is a challenge and I agree it would be nice to get a conversation going between some of the NorCal owners. I can see from this thread that you're are in Pleasant Hill, I'm in Danville and Someone else is in Livermore. There's at least three in a small geographic area.

Might I suggest that we meet initially at the Blackhawk Cars And Coffee which is held on the first Sunday of every month. It's a neat event with up to 700 plus cars of all types that show up. http://www.blackhawkmuseum.org/carsncoffee.html

I always go and I bring various cars, but if there is interest I'll be sure to bring my Red 90 ZR1.

If you have not been to Blackhawk you should attend some of their Saturday morning lecture series. Upcoming are Howden Ganly Formula 1 Driver, Lyn St James who has driven everything and Pete Brock who will be making a presentation on the Shelby Daytona Coupe. Last year he did a presentation on the 63 Stingray that he helped design. See their website for more info.http://www.blackhawkmuseum.org/

I realize this tread is not necessarily the right place to discuss this, so if need be we can start a new thread for Norcal owners.

Any thoughts?

Gary

Re: Just Failed CA Smog. Now what?
 

Thanks for your reply.

I was actually wondering where the left tool could be purchased. Any help?

Gary

Re: Just Failed CA Smog. Now what?
 

I got them at Harbor Freight.
I'm always at Cars and Coffee.

Sometimes I bring my Z or Firebird.

Re: Just Failed CA Smog. Now what?
 

Can't remember where I got mine but if your local you can borrow mine,I'm in Fremont.

Re: Just Failed CA Smog. Now what?
 

Go into Forum --> Club Regional Areas --> Pacific Region
and post up any events to attend. Get the word out and
they will GROW! Let us southerners know if there is a special
meeting and some of us will come up!
Ted

Re: Just Failed CA Smog. Now what?
 

I found the following when I was searching last week:

1) O'Reilly
2) Harbor Freight

When I was at O'Reilly's to buy the socket, I found out you can rent a 3 piece O2 sensor socket set (different brand than the one they sell) from O'Reilly's for free for 48 hours ($26 deposit that's refunded when returned). I rented this, but there just wasn't enough clearance for me to even get the socket around the sensor. I'm not sure if this is just specific to my Z or whether the socket they rent is just too thick.

Re: Just Failed CA Smog. Now what?
 

Thanks for the leads. I'll check out Harbor Freight as the O'Reilly one looks identical.

Gary

Re: Just Failed CA Smog. Now what?
 

Engine Coolant Temperature.

Re: Just Failed CA Smog. Now what?
 

I'm thinking about going on the 1st if anybody wants to meet me there.

Re: Just Failed CA Smog. Now what?
 

By there do you mean the Blackhawk Cars and Coffee? If so I plan on being there. I usually arrive by 7 in order to get a spot in the upper lot.

Gary

Re: Just Failed CA Smog. Now what?
 

:USFlag:That's the one Gary. You wouldn't happen to own a Black 91 would you?

Re: Just Failed CA Smog. Now what?
 

Nope, Red, Black interior.

See you there. What color is yours?

Gary

Passed! Passed! Passed! Woohoo!!!
 

I changed out the O2 sensors, engine oil, and went to the smog place recommended by my mechanic with the engine hot and I passed!! I don't think the O2 sensors did anything for NOx. The 25 MPH measurement actually went up from 459 PPM to 519 PPM. The average is 223 PPM. If anyone knows why my NOx is still so high and how I could get it down, I'm really curious to know. All of the other measured numbers are all below the average.

I think what made the difference is not anything I did to the car but in the values entered for the smog test! The previous smog place put "CORVETTE" instead of "CORVETTE ZR1" as the Model. They also entered this as a "California" instead of "Federal" car in the Certification field. Entering these values correctly actually raised the NOx MAX levels from 545 PPM to 757 PPM (for 15 MPH) and from 502 PPM to 696 PPM (for 25 MPH).

The passing report is below:

Re: Just Failed CA Smog. Now what?
 

Hummm...... interesting......

Glad you passed :-D

Re: Passed! Passed! Passed! Woohoo!!!
 

This is huge...I will double check my previous tests to see how it was tested.

As for the high Nox. Probably a small vacuum leak or old catalysts.

I'm curious how the smog guy got away with using Federal instead of California certification. It's a Ca car is it not? The 49 state Federal standards are no doubt less strict than Ca. which is potentialil why the Max limits were higher, about what they used to be in Ca.

I sure hope you actually get your registration and that I can convince a local guy to do the same.

Gary

Re: Just Failed CA Smog. Now what?
 

Would the difference be that cars SOLD in CA would be equipped somewhat differently than cars sold in the other states and therefore would have different emission requirements? For example I once saw a CA car that had 2 evap canisters in it vs the same model non CA that only had one.
