It can be yours for six bucks. I was going to give them a fair shake, but I cant order from them after that.

 

I'm waiting for the specials on a Cam shaft..Then I'll order the Rx7 Timing chain.................()

 

I understand placeholder files in the parts database. I expected to see a "not available" listed. Surprised to see a part number.

 

They just put up listings for what the manufacturer says they have. If Melling says that part number (whatever) is a timing chain for (whatever), that is what goes in the catalog.

Some parts suppliers have bounties for people who find errors in the catalog, for this reason.

 

bingo. most American suppliers (nobody manufactures anything), have agreed on a parts taxonomy. they key word being most.

and since most retailers just upload the vendors file (which was copied and pasted to begin with) you end up with Rx7 timing chains, and other nonsense.

 

Holy crap your right, now I'm debating wether I should get the $6 timing belt pulley or step up to the premium $10 one.

 

the premium one has a box that is printed in the USA

 

It's funny because of how true it is...

Automotive taxonomy is funny. Call up a Ford dealer and ask for a rear O2. Get a dirty toned reply "It's not an oxygen sensor, it's a catalyst monitor." Yeah, yeah, and it's not a minivan it's an SUV, it's not a doll it's an action figure, just get me the damn part.

 

yeah, well check out the RX7 engine mounts and see how those look....

other things like front main seal, do however work. i bought a few of them on clearance for like 70 cents a piece.

 

Going off the picture i always thought it was the oil pump chain

 

don't get me started on Ford, but my boss would say they slice the pie too fine.

we would call the rear oxygen sensor the oxygen sensor, because it is one. the front usually is both an oxygen sensor and an air fuel ratio sensor, because a wideband style sensor, is not an o2 sensor, but we realize that some people just want the damn thing that screws in the exhaust in front of the cat...

Ford actually uses different group numbers, so they differentiate too, its like 9G444 and 9G472 or something like that

 

air/fuel sensors don't actually monitor oxygen though, so calling it an oxygen sensor is completely false.

 

Wait... enlighten me with the semantics. So you are saying the thing I have hooked up to my wide band is called a air/fuel sensor NOT an O2 sensor? BUT the sensors I replace in factory systems that monitor fuel trims upstream are termed O2 sensors and downstream are catalyst monitors?

 

It's true from a certain point of view...

I thought widebands worked by pumping current into a narrowband type cell to change the switchover point, and the electronics deduced the air/fuel ratio based off of the amount of current required. But I'm admittedly not up on the latest technology.

 

Mazda calls the front one an Air Fuel Ratio Sensor, with a De-code of 18-8G1. the rear is is an Oxygen Sensor; 18-861.

Ford differentiates too, but they so crazy you can't go by what they SAY, you have to go by the group number (picture is also not usually tied to the text either, so its useless too, sometimes). actually Ford tends to call them HEGO sensors, when its a UEGO sensor.

just a for instance, there is some Escort headlight that is with GIMP and one without GIMP... there are LUVL sensors, driveshafts for California emissions and upper intakes can be lowers, its tons of fun, many many hours of entertainment.
