Default Is my clutch going?

Hi there, I have a 2002 WRX with 119,000 kms (74k miles) and have been at stage 2 for ~14k kms. I believe this is still the stock clutch.

I started smelling burnt clutch in my car last week, now it's happening pretty much every drive. At first it was only if I punched it in 1st gear, but now it happens even when driving very smoothly around town.

Occasionally I will see some smoke come out of my scoop/gap between hood and fender. Again, this may happen even when I am doing my absolute best to not abuse the clutch.

I have only smelled burnt clutch twice before from backing up an incline from a stop, and I have been taking it very easy on the car for the past week but I can still smell burnt clutch occasionally. I have not noticed any slippage, yet it still burns. Is my clutch on it's way out or is it likely that another part has failed? Please let me know if you need any more information.

Thanks

well if it looks like a duck and quacks like a duck...

It sounds like its totally shot at this point and should be replaced. Do get under the car if you can and take a look around to make sure there are no fluid drips or residual leftover to rule out anything else smoking from the scoop.

I had some smoke a few months ago after a launch and I determined that to be a bit of oil leaking somehow from the turbo onto the uppipe heatshield. I saw oil stains on the pipe. I don't do that anymore and haven't seen any smoke from that source since.

This smoke is just coming from around the clutch and it definately smells like clutch. But I will check it out to make sure.

Would I be better going with an Exedy OEM replacement or a stage 1 clutch? I know the 2002 transmission is weak and heard it doesn't like upgraded clutches.

the more OEM the clutch, the longer the trans will last, so OEM Replacement.

yeah do some research on the clutches your looking at and see what its best for..like how you drive your car, if you track it, how much power you put down, etc. hope this helps

My only power mods are 3" catless turboback and stage 2 ots cobb accessport tune, so I'm definately under 300 whp. No tracking.

Me and my buddy jacked the car up and looked around under there, we are seeing quite a bit of oil on the crossmember and all around the steering lines around there. We looked as much as we could for the leak, checking the tightness of all bolts around the apparent source but came up empty handed. My power steering fluid has remained at the same level for over a year, but my motor oil does drop a bit between fill-ups so I am confident this is motor oil.

I tried to make my clutch slip yesterday with a few 1st/2nd gear pulls and didn't notice any slippage what so ever, this was with the clutch fully engaged, not slipping with foot. I'm starting to think that I'm smelling burnt oil, not burnt clutch. My commute to school everyday is 35 minutes on the highway at around 80mph, then I turn off via an offramp. Even if I just pop it into neutral before slowing down and use only my brakes, I will get a sniff of burnt something right after the turn, sometimes I will see smoke. Confirming my belief that it's burnt oil and not clutch. Possibly some oil is dripping onto my hot exhaust when I take the corner?

Any helpful input?

If you are dripping going through turns, you are dripping everywhere... pretty simple...

Only you can say if the oil is bad enough to casue the problem, cause well, we aren't under your car...

75k isn't unherd of, of a clutch wearing out, much depends on the driver of the car, not the quality of the part...

So, get under the car with a bottle of simple green and a parts brush, scrub the hell out of it and pressure was off the rest of the crap (bearing in mind there IS an inspection port on the bottom of the motor, don't blow oil crap in there)

If the clutch is slipping, the clutch is slipping, you'll see it in a sharp rise in RPM.. and clutch smells like brakes, acrid, not "burnt" like oil...

The best way to check for a slipping clutch is to floor it from low RPM in 5th.

I know I'd be dripping everywhere, but it's only dripping onto my hot exhaust on tighter turns and burning/smoking. I am not noticing any clutch slippage at all but I will try flooring it in 5th gear at a low RPM on my drive home and see. Thanks for the help!

I tried flooring it from around 1800 rpm a few times in 4th and 5th and had no slippage that I could notice. Pretty sure this is just an oil leak and I need to track it down.

Actually, if you are going to slip in 5th, you'll slip near 4krpm....

There's no power being made @1800rpm... none...

Smoke out the hood scoop + no noticeable clutch slippage = valve cover gaskets.

Oh ok, that's what I thought you guys meant by low rpm. I did pulls from 1800-4500 and no slippage that I could notice.

Valve cover gaskets sound like fun, does the motor need to be pulled?

No. There's a howto on here somewhere. It's relatively simple but involves a lot of mixing and matching wrenches to get to the various bolts. And some contortion. Figure a couple hours for the pass side and less for the driver side. Have beer and Betadine handy.

That's good news. I just changed my spark plugs this past weekend so that procedure is still fresh in my mind. Probably a bit more in depth I'd imagine.

EDIT: just looked at a few how-to threads and it looks pretty straight forward. I changed my heater core a few weeks ago, this appears less difficult for sure. Just need to make sure it is the valve cover gaskets that are leaking then I will order the gaskets.

So i crawled under the car again and looked at the drivers side valve cover.. no leaks. Passenger side was hidden behind exhaust shields so I pulled the airbox and saw some oil residue down there as well as burnt oil stains on the up pipe heat shield. So relieved that it wasn't my clutch afterall.

Thanks for the help!
