Flamidation Valve Going Bad?
 

Car: 94 Talon tsi AWD, with lsd and stock mounts
Problem:
When I take off from a stop sign or light (even slowly) I hear my wheels spin. Started about a week ago. When I shift from 1st to 2nd, I hear the same squeal/spin. Same sound when I shift from 2 to 3 and now recently (since ysterday) from 3rd to 4th.
This sound is reminiscent of what would happen on hard takeoff and from 1st to 2nd in my 95 GST (except in that case it would happen on hard takeoffs, not slow takeoffs like I'm doing now)
All of the above described problem on my 94 talon awd is not hard shifting or anything severe - I do it at VERY low speed (in fact, I saw it was happening even without me going into boost).

History and background:
I DO shift hard and take off hard almost all the time and this is my DD. I stopped doing this a week ago and started shifting like an old lady for the last week until I know for sure that I'm not in the process of breaking anything.

What the hell is slipping? Why are my wheels slipping?

Your center diff is broke and you are now front wheel drive. That or your xfer case and driveshaft fell off somewhere.

Re: Wheel spin developed recently in all gears except 5th
 

If the transfer case fell off, how is my car still running? It's not dripping oil at all.
How will I know if my center diff is broken?

Re: Wheel spin developed recently in all gears except 5th
 

Is your car lowered? If so your alignment could be off. This will cause tires to sqeak.

Re: Wheel spin developed recently in all gears except 5th
 

Not lowered that I know of. I just bought the car from Kenny a month ago (TGPilot). He didn't mention that he had it lowered.

Re: Wheel spin developed recently in all gears except 5th
 

Check for uneven tire wear and tire pressure. Check you transfer fluid because it might of all leaked out.
"That or your xfer case and driveshaft fell off somewhere." Steve is just being sarcastic.
I would drive with caution until you know what is wrong with your car. Oh by the way welcome to the world of DSM (don't save money).

Re: Wheel spin developed recently in all gears except 5th
 

Dude,
I REALLY REALLY hope thats the case - uneven tire pressure. If it's just that, then lunch is on me!!!!!
Otherwise I'm REALLY fucked.

Re: Wheel spin developed recently in all gears except 5th
 

It's probably a belt squealing. Check them.

:cool:

Re: Wheel spin developed recently in all gears except 5th
 

Geez, this ain't that tough. If you are indeed actually hearing and feeling wheelspin, have a friend stand on the passenger side of your car a safe distance away while you nail it from a dead stop. If your friend sees your passenger side front wheel spin, your center diff is broken, plain and simple. If that's not the case, your hearing something else, than refer to the posts above for other sounds and causes.

When I have a welded viscous coupler on my car and no xfer case or driveshaft, it'll spin the front right tire at anything under 100mph without even getting on it hard. The front diff is open, so you've got a one wheel wonder if your rear diff isn't getting any power.

Re: Wheel spin developed recently in all gears except 5th
 

Yep, what he said :rolleyes:

Re: Wheel spin developed recently in all gears except 5th
 

belts're OK.

Re: Wheel spin developed recently in all gears except 5th
 

I think there's a clicking sound coming from the bottom - passenger side front.

Re: Wheel spin developed recently in all gears except 5th
 

Forget about what we told you to do, you are on the right track. Right near the down pipe & x-case is a flamidation valve that's problably sticking, causing it to chatter on acceleration from a stop.

Re: Wheel spin developed recently in all gears except 5th
 

Yeah, those damn flamidation valves can be a pain when they get sticky. Luckily they are pretty easy to free them back up.

Re: Wheel spin developed recently in all gears except 5th
 

Can you say WD-40?

Re: Wheel spin developed recently in all gears except 5th
 

Double U Deeee For Deeeeee

Re: Wheel spin developed recently in all gears except 5th
 

Is it that simple a fix? WOW!!
I'll go see.

Re: Wheel spin developed recently in all gears except 5th
 

Where the hell have you been all these days dude? I hate to say this but I missed ya! :rolleyes:

Re: Wheel spin developed recently in all gears except 5th
 

I was in WI for 4 days again. Now I am catching up in the garage and I will be heading out to Canada soon for 3-4 days.

Re: Wheel spin developed recently in all gears except 5th
 

Jeez man! I sold the car to someone who said they were going to take care of it and it sounds like you are thrashing the shit out of it! Oh well it is your dollar...3600 of them to be exact. :rolleyes:

Do me a favor...if you terminally break the car...DONT'T CALL ME BITCHING ABOUT IT! :rolleyes: ;)

Re: Wheel spin developed recently in all gears except 5th
 

Nah - I haven't been beating the car. Dont worry though - I think you still sold me a nice car. I rewired the fuel pump, put in a Walbro 190, leds under the car, neons inside and finished the timing belt and water pump.
Planning to put in 650 cc, 2g maf, socket the ecu and chip it for the 650 cc, safc 2, electronic boost controller, HG + ARP head studs, fix the exhaust leak, more gauging. The finally dyno it with Shane. ;)

Hey the price was 3600 plus the plane ticket remember? LOL! :rolleyes: I wish there had been more time for a few beers before you left.

I know you had driveline issues - what did you have to fix? Let me know so I won't look in that direction - so I'll look into stuff you didn't need to fix and it could be showing up just coz of age. I may look into a Shep tranny next year.

Re: Wheel spin developed recently in all gears except 5th
 

Ahhh, it's all becoming clear now. If youz gotz da neonz undah the car, youz don't need dat center diff messin up ya ride. :rolleyes:

Re: Wheel spin developed recently in all gears except 5th
 

Let's see driveline issues:

Tranny case split...replaced the tranny.
Transfer case leaking...replaced T-case with tranny from same car.
UV joints in prop shaft making noise...replaced all three.

That's about it for the driveline issues I knew of.

Re: Wheel spin developed recently in all gears except 5th
 

So did wd40 fixed your problem?

Re: Wheel spin developed recently in all gears except 5th
 

:rolleyes:

Re: Wheel spin developed recently in all gears except 5th
 

Neons!!?

Re: Wheel spin developed recently in all gears except 5th
 

Oh jeez...

Re: Wheel spin developed recently in all gears except 5th
 

It stopped ticking dammit. Now it's still slipping, but the clicking sound went away.

Re: Wheel spin developed recently in all gears except 5th
 

How do I know which one it is? I looked and there's didn't seem to be anything looking like a valve. Would anyone happen to have a pic?

Re: Wheel spin developed recently in all gears except 5th
 

Hey Kenny,
Do you have any idea how many miles that tranny and t-case had? Or if it had ever been rebuilt?

Re: Wheel spin developed recently in all gears except 5th
 

You can't miss it. its right near the down pipe & transfer-case.

Re: Wheel spin developed recently in all gears except 5th
 

It must have fell off. So that must not be your problem.

I would start looking at the center diff as we said before.:cool:

Re: Wheel spin developed recently in all gears except 5th
 

Holy shit I damn near fell out of my chair after reading that!

....and that!

Re: Wheel spin developed recently in all gears except 5th
 

I just checked mine yesterday when I was working on my Laser's clutch issues. You'll find it RK.

Re: Wheel spin developed recently in all gears except 5th
 

But you know, now that I think about it?!?!?! You really should find another flamidation valve and swap it out before you go any further. Or you'll just be wasting our time and yours. :cool:

Re: Wheel spin developed recently in all gears except 5th
 

I think there is a Vfaq or Tuners tech article explaining the swap.

Re: Wheel spin developed recently in all gears except 5th
 

Yeah, I read that VFAQ when we swapped that 6 bolt in my friends 2G. We broke off the valve when we were swapping the engine. Good thing it was an easy fix!

Re: Wheel spin developed recently in all gears except 5th
 

With LED's and neons, why even bother with driving the car? Just pose in a parking lot with the door propped open and your leg hanging out! Any plans for a larger turbo to go along with those 650cc fuel injectors?

Re: Wheel spin developed recently in all gears except 5th
 

Neons can be what causes the flamidation valve go to bad in the first place. The frequency of the fluorescent light can cause a partial interference with the natural frequency of the flux capacitor on the flamidation valve leading to valve failure. I wish I could find the damn Vfaq on this, it spells out this issue quite well and includes pictures.
