I've been looking at 993 for a while, found a nice 97. But i am concerned by the amount of valve train noise, It sounds like mechanical lifters that may neeed a bit of adjusment. How serious and how expensive might this be.

kahuna,
The 1997 993 has hydraulic lifters that do not require adjustment. A certain amount of valve train noise is normal (and desirable from a cahracter standpoint). Is the engine sound tray on or off? If it is off, noise is louder.
Do you have a real name?

Kahuna,
As Mike said, some noise is normal. Get someone who knows 993s to hear it...may be fine. If you need to replace any of the lifters (not uncommon), it's an easy DIY, if you are so inclined (lots in the archives on this). Hope this helps.

After I took the engine sound tray off, I have seen significantly increased valve noise, especially when starting up in the garage and there is nothing wrong with my valve guides. Just a FYI. Good luck!

Collapsed valve lifter or lifters could be the cause of your noise.
My 97 has now been in twice for lifter replacement on the driver side already this year.
First time all 6 were replaced, then after ~1000km the "ticking" was back. Again, 2 lifters, same side have been replaced this time under full warrantee. My car has just 30k miles on the odometer.....and has been dealer serviced since new.
