Curious about what these parts are

[navymx3]

Ive posted a little bit on here, trying to figure out my car, and i got a picture of my engine off the net, and I used MS paint to highlight and try and label things to my knowledge and my guesses. Please, acknowledge or correct me, and help fill me in about the rest of the engine, because I really want to improve my vehicles performance, but I need to start with knowing what exactly is in under my hood. Btw, this IS NOT a pic of my engine that is in my car, mine is a little different, this is just the same K8 that i have, I havent gotten a picture of mine yet, hope to very soon

Ok, I don't understand everything in that pic (my eyesight is failing) but I'll do what I can.

You are right on the power steering reservoir, brake master cylinder, CAI, pcv, and throttle position sensor.

The tabs you marked "wtf are these" are the hooks to hang the engine from the hoist.
I don't know what you wrote in the square mark between the CAI and the throttle body, but that's tha mass airflow sensor.
What you marked "coil" is the windshield wiper motor.
The tube you marked "fuel injector line" seems to be the PCV connector between both cylinder banks.

Hope I'm not missing anything...

What you think is the MAF, was supposed to be circling was is behind the air intake, which i believe is the idle air control, its connected to a black cylinder below the throttle? tahts what ryan told me it was.
And if that is the windshield wiper motor...where is the coil? jw.

[Inodoro Pereyra]

The IAC is on the throttle body. I'm not sure on which side of it, but of Ryan told you it's the IAC, it's the IAC.

About the coil, I'm not 100% sure (never owned a K8), but for the shape of it and the distributor cap, I'd say it's inside the distributor.

[navymx3]

Ahh, mk. Well, Im sure ryan is right, apparently hes been working on these cars for like 16 years now! lol

[Inodoro Pereyra]

Yep. I don't know how long he's been working on them, but he knows what he's talking about.

[Ryan]

eh? people have been for 16 years, I'm only at 2, but at least a few hours a day...

I have an IAC pic for you.

Let me rummage.



This is a B6 throttle body. Yours should be essentially the same

The yellow is just a valve so the throttle doesn't slam shut. The red is the ring that holds the cable, and turns the pulling motion into rotational motion to open the throttle butterfly.

The blue/purple is the IAC. It works using coolant temerpature and throttle position to change the airflow allowed in at idle.

The green is where the throttle position sensor TPS is supposed to be. Its just removed thats all.

The bolt on the butterfly valve is there only for storage convenience.



The coil is indeed inside of the distributor.



IF you're having trouble finding out what is what, find it in the online manuals.

A bit of common sense usually does though. The lines in the car only carry so many things.

wires carry electricity and electric signals.

black hoses carry fuel, coolant, ps fluid, and air.

steel lines carry brake and clutch fluid

bigger aluminum lines carry air conditioning fluid, called refrigerant.

I wish I could see the picture, but these work computers wont allow pictures from photobucket. it does however from Imageshack, if you could upload a pic from there? then I could really see just what your talking about

[navymx3]

Sorry for double post.
This is the distributor I was talking about ryan, the guy I got the car from said he did something with it, like cusomized it or something. Sorry for the darkness, its midnight and i didnt have a very good flashlight.

And this is my throttle, and what I believe to be my IAC...is this is?

[Ryan]

lmao, kudos for figuring out the pictures, but really man, post some taken in daylight, or even with a flash, lol.

[navymx3]

Haha, well it was with my camera phone, and it doesnt have a flash, but as soon as i get home, and use my fiances camera, ill post some better pics once i get a better income, I hope to really start working on it, and post a worklog

[navymx3]

Alright, well I finally got pics of MY engine, using my fiances camera, got some closeups of what I am curious about, and just some questions. Ill add captions to some of the pics im really wondering about or worried about.

Someone told me about this lil black box, and to put a paper clip in linking 2 of the circuits? mind telling me again, and which ones?

I saw this and am kinda worried...what is supposed to be plugged in here? anything major? not too sure.

Im guessing this is what everyones disty looks like...the guy I bought it from said he customized it somehow?

Ok, this is my throttle body...please, tell me what the black cylinder is below the throttle coil, and what is on the left side of the TB that has a plug connecting to it?


looks like a lot of rust under there, anything you guys suggest I do?
Well, thats my car and engine if you guys need me to take anymore picures, please just ask. And ill take them ASAP
Thanks for your time

Okey dokey...

The cylinder with the plug under your throttle body is your IAC.

The plug on the side of your disty is your ignition coil. The other pug on the center of the disty cap is the "custom work" that guy did. He just modified the cap to work with an external coil. If you follow the cable connected to that terminal you will find the external coil at the other end.

EDIT: I forgot, the little box is your diagnostic box. You should NOT connect anything during normal use. If and when you need to diagnose a problem, you need to jump a set of terminals, depending on what you need.

[navymx3]

Ok, someone said that since my car is having a rolling idle problem, and since it idles high, around 1500, that i should jump something in my diagnosis box?do you know what that may be? and for your eyes, i hope those pics better explain what i was trying to ask

[Inodoro Pereyra]

Ok, to diagnose, you need to jump TEN (that's Test ENgine, not "10") and ground. Then put your car in contact and count how many times the "check engine" light flashes. That'll give you the DTC (Diagnostic Trouble Code) number.

Yeah, those pics are much better, thanks.
