My visit to this website

[993C2]

Hello

I recently purchased a 1997 Porsche 993 C2 (she is a beauty) and while I think I can control my speed within city limits, I can't wait to take this car out into the country on some twisty roads.

I also purchased the Valentine One radar detector and hopefully I will learn a thing or two in these forums about my V1 and the possibly protect it may provide.

Cheers ...

I have to say I am not sure I understand why this site is littered with these messages for the newbies. I understand the need to protect this site from spammers (I assure you I am not a spammer, I am here to learn about radar/laser detecting).

But it makes reading this site right now (as a newbie) kind of hard.

Oh well ...

Congratulations on your new C2. That's a fine sports car, one of my favorites (and many other people's favorite too, judging by their resale value).

Make sure you keep the O2 passages in the heads clean, and if not already done, remove the lower engine cover to provide a little more cooling. This will help you get the most mileage out of those soft valve guides (unless of course they've already been replaced with the new harder guides). Great car, and they sound so damn nice.

I was under the impression that radar detector use was strictly prohibited in Canada. Be careful with that. If so, a Bel STI, STI-R or Escort 9500ci might have been a better choice because they're the only detectors out there that are undetectable by RDDs.

It's a annoyance right now, but it does help. There are lots of folks scanning these forums for places to post ads about cell phones, viagra, 409 scams, etc... By limiting their ability to post links and pictures, it makes them go somewhere else. It's also a nice incentive for newbies to participate.

Hang in there. You'll be out of the wood before you know it. Besides, I really want to see a picture of that C2.

Knowing nothing about air-cooled Porsches...wouldn't the fan just pull air from under the engine?

Same concept as keeping the hood shut when the car is overheating: allow the fan to pull as much air directly from the engine (bay) as possible.

The 993 (1995-1998) had the last air cooled Porsche engine, and it was the first 911 variant to incorporate the use of hydraulic valve lifters. This meant there were no more valve adjustments, making the 993 a much lower maintenance 911 than any of its predecessors. Unfortunately however, this new valve train had a flaw that did not surface until long after the cars were in the marketplace. The valve guides that were chosen were very soft and over time the lateral forces would wear the guides. This would result in a loose valve stem which would ultimately lead to poor valve seating, bad compression & loss of power.

This problem generally shows it's ugly head some time after 60,000 miles. Because most Porsches see infrequent good weather use in the range of 6,000-10,000 miles a year, most of these cars were well out of warranty before this problem surfaced, and Porsche was already deep into the next model revision, the 996.

This problem seems to be more common in cars driven in hot climates or those that have seen significant track use. These cars have an underbelly pan that surrounds the engine. The primary function of this pan is to reduce turbulence and lift at high speeds. Most experts recommend the removal of this pan to provide more cooling which generally prolongs the life of the valve guides.

Another issue to stay on top of is the coking and clogging of the O2 passages in the heads. If ignored, they will clog. In 1996 the 993 engines shifted from OBD to OBD2. The OBD2 cars benefit from a 12hp increase over the 1995s, but they will trip a 'check engine' light if these O2 passages clog, making it difficult or impossible to pass emissions testing. Once clogged, the only real solution is a top end rebuild, which can be costly. Most experienced Porsche mechanics have learned to routinely saturate these passages with solvent and blow them out with compressed air to prevent clogging.

In best case, if taken care of and kept cool, you can get 100,000 miles out of one of these engines. If ignored and abused, you'll be digging into your wallet for a rebuild much sooner. If and when you do rebuild the engine, there is a new improved harder valve guide that corrects the vavle guide issue.

Sorry to drift so far off topic.... I sort of went Porsche geek on everyone.

LOL ... I think your Porsche Geek kind of spooked me. But it's all good.
