Quote Request: Catalytic Converter and Timing Belt Cover

visuvius · 03-17-2009, 12:30 PM

Hi Aaron I have a 93 Turbo and am wondering how much these two parts are. I failed a smog test

The guy wrote down "missing timing belt cover" as one of the reasons I failed so I need that too.

thx.

25508-74110 - $367.69 - Cataltyic converter, front
25576-74030 - $9.68 - gasket, converter to discharge elbow
90917-06056 - $6.84 - gasket, converter to B-pipe
17410-7A050 - $733.97 - B-pipe including secondary converter
90917-06049 - $4.85 - gasket, B-pipe to muffler
11322-88380 - $64.78 - Upper timing belt cover
11329-88380 - $9.54 - Gasket, upper timing belt cover
90105-06035 - $0.91 - Bolt, timing belt cover, long (x2 = $1.82)
91511-G0620 - $0.49 - Bolt, timing belt cover, short (x2 = $0.98)

What exactly was over the limit? Cats primarily control hydrocarbon emissions. There are a number of tricks that should be followed to optimize the efficiency of the emissions control system. Was the car totally warmed up (recently driven under load to put sufficient heat into the cat), ignition timing set correctly, air filter clean, etc?

A timing belt cover is not an emissions component and should not result in failure in a California smog test. Adjustable cam pulleys are illegal in CA, but that's a different issue. I suspect the smog tech was simply pointing out a missing part rather than failing your car based on that missing part. If he specifically said otherwise, it might be time to ask some more questions and see whether he really knows what he's talking about, or just looking for ways to make extra money off you. If he's just BSing you, you might be able to find a more knowledgable, more MR2-friendly smog shop where they actually know how our cars work and what makes them run clean.

Hey Aaron, I hope this helps: MR2 Failed Smog :(

He failed due to high HC levels. I spoke to him Monday and the smog shop he brought it to were all idiots. haha. As always, thanks for your help.

My NA did this. To pass I just drove around on the freeway for ~30min to warm it up good (at 80mph I sti close to 4krpm....enough to warm her up good lol).

Have it setup so you can pull in and take the test right there, and you'll most likely pass. I went from failing to passing w/ flying colors

Thanks, that does help! So it's really the lower timing belt cover he needs:

11321-88380 - $57.10 - Timing belt cover, lower
11328-88380 - $20.15 - gasket, lower timing belt cover
90105-06035 - $0.91 - Bolt, timing belt cover, long (x1 = $0.91)
91511-G0620 - $0.49 - Bolt, timing belt cover, short (x5 = $2.45)

I'll chime in with whatever help I can offer on the other thread as well.
