Smog test prep reveals heat related damage and deferred maintenance

Post by GRNSHRK »

Yes, I will once again try to go through a "legal" smog test, which up until a few years ago was not a problem, until the glorious state of CA decided to fail me due to non-CARB compliant headers :twisted:

What started as a simple check of the air filter and checking out the spark plugs, I found a lot of issues which were due in part to old age but also the excessive heat that comes off the headers, as they never had the correct gaskets with the built in heat shields :-?

In the pix you can see that not only was the spark plug wire loom warped, but also 2 of the wires actually had partially melted insulation :shock:

I also found that the breather/vent hose had not only cracked, leading to oil everywhere, but also crumbled upon removal ](*,)

The second set of pix shows all back together now, with the proper heat shields installed, new spark plug wires, and even a little bling on the wire loom \:D/

That's just pinstripe tape which will likely blow off in a few miles, but it looks cool at least for now :wink:

First, the before pix #-o

Follow up, after finally finding a smog shop that would actually perform the test without any issues with my headers and exhaust, I had to go THREE TIMES to finally get her through the process ](*,)

The first time the tech couldn't perform the evap test as they didn't have the right adapter to fit the tank filler neck #-o

They called me back the next day as one of the other techs claimed that they could bypass that test, so I sent back the next day, only to develop a misfire, WHILE on the dyno :-?

Since I hadn't changed the spark plugs or O2 sensor, since who knows when, both the tech and Klaus suggested that I swap those items out for new, and Klaus talked me into trying NGK plugs instead of the Bosch silver :-k

The O2 sensor was a real bitch to remove and I had to buy the proper offset socket to get it out :-({|=

But I went back yesterday for the third time and passed, all good =D>

Here's a shot of the old O2 sensor and the green shark on the dyno \:D/

nice, glad it's passed!

are those headers grandfathered-in stahls? or did they wave you by?

in case it's useful, I do have my old set of E12-based M90 cast headers and downpipes kicking around. Just tripped over them earlier today, in fact.

The headers are so old that they are not CARB compliant :(

Years ago I went to a referee, thinking that was the process for getting grandfathered in for life, silly me [-X

This the only smog shop that I found, thankfully local, that would do the test and look the other way regarding the headers and custom exhaust [-o<

And keep those M90 manifolds and down pipes :shock:

I may eventually decide to go that route, should I hit a snag in the future :-({|=

Got my new tags yesterday \:D/

So I decided to take the opportunity to peel off the past quarter centuries worth of previously issued tags :roll:

Super glad to be done with this for another 2 years and have found a smog shop that is actually willing to perform the test, regardless of my exhaust =D>

What's the penalty for driving un-smogged if thats a word and do they actively police ? What if u're visiting from out of State?

no issue if out of state, provided you're either visiting or get in-state plates within a certain amount of time.

incomplete smog will prevent your registration from renewing.

Dmitri, you have a PM :-"

As far as getting caught with out of date registration, luckily the "men in blue" have a lot bigger problems on their hands than us "law brakers" :roll:

That said, and while I don't want to find out the hard way, I surmise that your car could be impounded for repeated lack of current registration :shock:

Here in California, we're considered quite the "nanny state", with the most harsh laws against cars like our beloved 6ers, which we drive so much :roll:
