Cost of these 993 repairs

adamb113 · 01-07-2005, 06:22 PM

I'm looking at a 95 993 with 94,000 miles on it and I think I would be looking at the following maintenance in the next year if I buy it. What are the ball park costs of each of these services at a shop/dealer
Clutch?
90k service ( wasn't done yet )?

Claning out the carbon buildup issue thingy with the thingy tube that causes the red light to go on?

Anything else I should ask about or look for with a 94,000 mile car?
Thanks,
Adam

Clutch parts are about $1600, some take the opportunity to get rid of the dual mass flywheel. All in, should be around $3k to $4k.

90k service is probably around $1k at the dealer (I'm guessing here a bit).

Carbon buildup issue turns on the check engine light, which is yellow, and doesn't affect '95s. That could be $6k or $7k to fix, or search on Rennlist for less expensive alternatives. But, like I said, a '95 shouldn't have that problem.

Someone chime in with more accurate prices.

Chris.

The 90K service is the big one.

Figure on the following being done at 90K

Sparkplugs
Caps and rotors]
Belts (including PS belt)
oil and tranny fluid
All filters (air, fuel, cabin)

Chances are good that unless they were done sometime fairly recently, you are probably coming due for valve cover gaskets. The lower ones aren't too bad, the uppers are expensive to replace.

A 90K with valve cover gaskets will set you back over $2000.

I would not be set on replacing your clutch just yet - it may have been done already or it may not need replacing. When it needs replacing, figure $3 - 4K

Thanks guys! Good info.
I'm loking at a 95 with 90k on it. The guy hasn't done any maintenance on it recently. So I'm trying to get a feel for what would be coming up and how much in the next year or two. The real bummer is that when I went to go look at the car this morning I found two rust spots!! Each about the size of a silver dollar. I have never heard of this sort of thing since they started galvanizing. One is right under the right headlight. The other is on the left fender just as the sheet metal bends under to the wheel well ( where you would expect tire kick up to hit). What is a good estimate for this repair. I would imagine one of the better ways to deal with this is to get two factory origianl fenders. Strip them and then paint to match. I imagine that any paint job on the existing spots would be very subject to future rust problems. Any Ideas?? Cost?? Is 2K per side a good estimate?
Thanks,
Adam

Porsche cars have a ten year body warranty, as long as the vehicle has been serviced and inspected. Call the Porsche dealer and check if that would be covered first.

Make sure this is not your current problem.

Adam,

Have you had a PPI done on this car? It would be well worth the expense.

Unless the PPI showed otherwise, I’d count on a 30k tune-up, as others have suggested. A 30K tune-up can run from $600 to $1,000, depending on where you go and what they include. Are you mechanically inclined? Much if not all of this can be DIY’d, saving tons of money. The spark plugs (actually only one of the plugs) are the most troublesome part. The rest is pretty easy.

Has anyone mentioned flushing the brake fluid? If the previous owner has not done much maintenance, he has probably not done this. It’s pretty important to do this every year or two, depending on use (track, etc) and climate. It’s also an easy DIY job. Check Pelican Parts for the “Motive Power Bleeder,” about $40 or so, plus some ATE fluid. DIY for $40 for the tool (and you keep the tool for the next time around), plus $30 for two liters of fluid, or pay a shop $150 each and every time.

Valve cover gaskets are another thing you can DIY. A shop should charge <$500 for this. It’s mostly labor, as the gaskets themselves aren’t that expensive.

As Chris said, the 95’s are immune to the carbon buildup issue, as the 95’s have OBD1 and the later 993’s have OBDII. A ’95 is a good choice for this reason. Add a chip for <$500 and you’ve got the same HP and torque as the varioram cars.

Do you have reason to believe the clutch is gone? If not, no reason to replace it yet. A PPI should reveal how much life is left.

As for the paint repair, cost will vary according to how good you want the repair. The most expensive would be a complete re-spray of the affected panels, which will be $$$$$. You could sand and spray the spots yourself with a can of touch-up spray paint. It won’t be anywhere near perfect, but it will only cost the bottle of spray paint and you can do it yourself. Or any $ amount in between. But like MMBRAZIL said, why do you have rust spots? A bad previous paint job? Un-repaired rock chips that have spread? A PPI should reveal this.

As for anything else a high-mileage car might require, how about shocks? Does it still have the original shocks? If so, they are toast. The cheapest solution would be a replacement set of Bilstein HD’s, with install and alignment and corner balance, would probably run $1500 - $2,000. You can go up from there, if you choose more expensive shocks like PSS9’s.

And of course check the condition of the tires, but that is tru of any used car purchase.

A final note: I recommend staying away from the stealership. Find a trusted independent in your area. Perhaps someone on this board can recommend a mechanic in the Boston area (make a post on the 911 board: “Anyone know any good mechanics in Boston?”), or get involved with your local chapter of the PCA and get some recommendations from them. A good first job for the new mechanic of your choice is the PPI I mentioned above.

Good luck and keep us posted!

Adam,
What are you planning to pay for this car?

Chris,

Just wanted to chime in on the carbon buildup issue. It is my understanding that '95s are affected just the same as 96+. THe difference is the more sensitive computer which triggers the CE light in the later model cars.

ChrisL · 01-15-2005, 08:21 AM

Yes -- I meant that the light doesn't come on, not that the ports don't get clogged on '95s just like all the others.

Chris.

Kang,
Thanks for the great info.

So with the carbon build up issue... Since the probelm is the same but the sensing is different,.... What will happen when the build up gets to be to much? failing emissions? other problems?

Larry,
I haven't come to a final price yet but it will definetly be less than $20.
It's really been neglected. All the wrong signs are there
No reciepts, worn tires, no big maintenance items done, shocks etc, didn't do wiring harness recall. Hasn't done 90k maintenance and he approaching mid 90's mileage. Unfixed rust spots?
It shows all the signs of somebody short on cash and cutting corners.
I have the means to work on it ( barn with a lift and a bunch of tools ), so it may be a good match if I can get this guys head out of the clouds ($24k) and scoop it up for a good price.
We'll see..................
