Hi all,
Well, my little Red finally had her 90,000 mile birthday and at first blush, she still seems to be running strong ( Likes drinking a quart every 1000 or so miles). I'm still rather new to the 993 C4, but me being somewhat handy with a wrench (and also being able-bodied to move around now since my illness), I was wondering what the 90,000 mile service entails, and if it is feasible to do at home.
Also, if it isn't totally feasible, how much about does this maintenance cost?

Hope you are all doing well. I haven't posted much here since I got ill last March. But on the eve of the one year annivesary of my illness, I have some good news to share with you all - I got the doctor to sign off on my ability to drive a car again. So now, I'm still limited to literally driving to the corner store and back, but still being able to drive (and a Porsche at that)- that is happiness.
Cheers!

Hi saphriel,
I'm afraid I haven't got any advice re service , my wrench manners aren't all that civilised , but your post has touched me to post back.
fantastic news that you're back in the driving seat and that lil red is pulling strong , I hope you'll soon be driving much further afield than the corner shop ..

Sorry for the OT reply .... On with the thread!

Since you are local, give a call to Redmond Euro!
18014 Redmond Way Suite C-25
Redmond, WA 98052
425-376-2655

They are a great shop, & work on both my 993's!

I believe the 90k is just all fluids, filters, belts, plugs Cap & rotor, & lubing & checking a bunch of things.

Glad you got the Ok to drive, not sure I could do that!

I think there are many who do their own services on these cars; it all depends on just how handy with a wrench you are. As far as what's entailed in a 90K service, a comprehensive check list of exactly what needs to be performed can be found if you do a search on it. Good luck and congratulations on your improved health.

I believe the 90k, is the same as the 30k, and 60k, i.e., Major Service.

I would also add replacing the SAI Check Valve if it hasn't been done lately.

If it's the original.....have fun getting it off.

Mine at 60K was so frozen/rusted in that we had to remove fixture that it screws into, but that assembly in a vise and add some heat to break it loose.

When are the caps and rotors inspected ? My car had the 60k service done recently and when i changed my dizzy belt 3k's later it did not look like the caps and rotors had been inspected (and they had certainly not been changed). The caps looked as they had seen their best days, so i put in some new ones .
