Recommended Posts

hello! new guy here from ottawa, ontario, canada.

bought a 02 C4S a couple of weeks ago and absolutely loving it.

some things need to be fixed on it like front cv boots, new rear tires, amd some other minor things...

one thing I noticed when it was on my buddies hoist is the metal lines travelling underneath the passenger side had some kinks in it. looks like a diy jacking gone wrong to me. anyways, what are those lines? coolant lines? heater core lines? I would like to replace the section that is kinked but having a hard time figuring out what they are for.

Those lines also include brake and clutch lines - best investigate the damage further.

are you sure? the brake lines and clutch lines look to be on the drivers side, those look great. these are thicker lines, maybe 1/2 " lines. never seen clutch and brake lines that thick. I am suspecting its these...

sure looks liken it anyways.

6 & 8 or 6 & 10? 8 looks to be the washer between the flanges.

thanks again.

ill contact my porsche dealer and give them the vin....at least I now know what lines they are.

Yes, 6 and 10. Sorry for the typo. Good call giving them the vin to verify fit.

one thing I noticed with this car is after a good spirited drive or a very short one, the car will spew out blue smoke when you start it up the next time around. it eventually goes away, faster if you just drive off immidiately. and it doesnt do it all the time either...

the aos was replaced last month by the previous owner. ive read that its normal to do as long as it goes away, I see lots of topics about this very issue it but theres a LOT of blue smoke on start up sometimes. my mechanic (who is a subaru guy) seemed pretty concerned when he started it and moved it on his hoist. I did beat her good on the way to his shop. lol

Thought I'd bump this. The battery draining issue was actually a bad voltage regulator.

After installing a new battery and that one only lasting about 3 start ups, it was pretty obvious I had a bigger problem.

I google'd the issue I was having ( slow discharge on idle, battery starts at 13.7 volts when idling, and then slowly drops as you let it idle. After 10 minutes, I was down to the 13.3 volts range with just idling, no load or anything on it....and still going down. While driving, the car would go down as low as 12 volts after 20 minutes of driving)

Using pelican parts how to's - Took me a whopping 45 minutes to pull the alternator out. While I was there, i removed the TB and intake plenum to get access to check the ground there...Took that, and the main engine ground off and cleaned them up. they already looked pretty clean though....

Took out the alternator and removed the voltage regulator, when comparing to the new unit, you could see the OEM unit had significant wear. The brushes were down to about half of what the new unit had. My theory is that when then engine got hot,the brushes were making very little contact and wouldnt keep the charge going.

Installed the new one, re-installed everything, and started her up, stayed at 14 volts the entire time.

Now I can drive the car without carrying a spare battery in the frunk. lol
