I got my car back from the shop today and it runs and got it insured and drove to school the timing is set to 10 degrees btdc and the performance seems better although it idles low 800 rpm and sometimes goes lower to 300 rpm even when started and sounds like shit. also I noticed that there was a pretty loud and bad sound coming from the camshaft when I first started it and it got a little better. it kinof sounded like squeeking and rubbing and rattling noise from the camshaft and distributer.... the rubber rubbing sound was especially weird...

oil pressure according to my gauge is 1 bar at idle 800-900 rpm and it gets a bit lower and goes up when iddles I'm guessing goes down to .7 bar sometimes and a few times i saw it dip to almost zero just for one second.

at 2000 rpm I think it was around 4 bar haynes says it should be 5-7 bar.



also question about my headlights today it was raining and dark when I was driving home and I was going 60 mph and could not see shit in front of me other than the trraffic lights I could not see the lanes at all. I had my healdights on and also high beam and they work but it looked like I was driving with no headights....

also after driving again I got a horrible headache like usual, I"m still dizzy and have blurry vision so I paid 60 bucks and got a carbon moxide dectector it has a digital readout from 30 ppm to 999pm which would mean I'll die after a 10 minute drive.

my CO detector says that 30ppm is still dangerous and CO obviously can cause death and smaller amounts can cause brain/ heart damage.

I'll see my reading tomorrow. If it detects high CO like I expect I might go to the mechanic one last time and tell them about the high CO levels and have them try and find the source.

if they can't fix it I've decided to trash the car asap so I stop wasting money and buy a better car.

Your idle should be at 950rpm.

It sounds like you need to make a slight adjustment to the idle speed. There is a screw in a kind of tube-looking thing, coming out at an angle from the front of the air plenum (that's the bit with the throttle body bolted to the left of it). Get a screwdriver and give the screw a quarter of a turn anti-clockwise until the idle speed sits just under 1000 rpm (Don't adjust anything else!).

Now, Tim. Have you tried stuffing some foam in the gear lever hole yet? If you trash your car for the sake of a few cents-worth of foam rubber, I for one, will be very angry, after all the advice you've had from me and other board members, and I suspect others will too (Khal is already not talking to you anymore!)

If you ditch the car, you'll prove that Lizard was right all along: that you shouldn't have ever bought a Porsche in the first place.

I'm sorry if this sounds harsh, but really, we've all tried our best with you and now you're talking about forsaking all that good will. Please persevere, for all our sakes!

And you shouldn't be driving a car with that much CO. You're getting headaches, the next thing that'll happen is you feel faint then you crash, hurting yourself or someone else. Take care Tim.

yeah but my car is a piece of crap so it doesn't matter. iddle will drop to 200-300 rpm until it warms up, I can raise the iddle a bit so it goes to 950 when it warms up.

all those squeeking and rubbing / rattling sounds from my camshaft and the oil pressure which I think is low probably mean my engine is going to blow up any day.

actually I don't care about any of those things as the car isn't really drivable with what I think is CO leaking into the car. I'll find out tomorrow.

I don't feel like I'm dizzy when driving but then when I park and get out of the car I notice that I'm walking like a drunk and my head feels like its floating above my body

I think my car is ready for the junk yard, it's running but it died a long time ago....

Mike I want to keep my 924 but I don't feel like dying from fumes and spending all my paychecks on a piece of crap which I've spent a ton of money on.

I just paid the mechanic over 300 dollars + the towing.

I know what you mean I'll try the foam in the shifter etc this weekend.

I'm going to also place the carbon monoxide detector in various spots in my car and see if its gets a higher reading in the back (hatch) or front to help find the source.

maybe i'll get lucky and that'll find the source. all the mechanics I went to have no idea what it is.

hey at least if I trash the car I won't have to make a million posts

9 ppm
EPA residential standard - not to exceed 9 ppm in 8 hours.

35 ppm
EPA residential standard - not to exceed 35 ppm in 1 hour.

50 ppm
OSHA workplace standard - not to exceed 50 ppm in an 8 hour period.

200 ppm
Slight headache, fatigue, dizziness, nausea after 2-3 hours.

400 ppm
Frontal headaches within 1-2 hours.
Life threatening after 3 hours.

800 ppm
Dizziness, nausea and convulsions within 45 minutes.
Unconsciousness with 2 hours. Death within 2-3 hours.

1600 ppm
Headache, dizziness and nausea within 20 minutes.
Death within 1 hour.

12,800 ppm
Death within 1-3 minutes.


I thought this was pretty interesting, it says that the tailpipe exhaust of a car engine can easily produce 70,000 + ppm of CO, 12,800 ppm will result in death in 1-3 minutes

this sounds pretty scary, I get headaches, dizziness , blurry vision after a 20 minuter drive home with the windows open so I'm expecting my detector to go up to its max reading of 999.

Try the CO detector right around your shift boot, you said you could feel some air coming up from it earlier. Then try the dash vents that are open, under the passenger and driverside footwells, definatly around the hatch area like you said. It can't be far...one thing I've always liked about the 924 is that it's so small compared to working on a truck.

I still think you need to check the line that comes from the exhaust right where the two tubes join to one, up to the EGR valve. It's common to be disconnected. I had the same problem on my old '79, and all it took was 10 minutes to seal up.

As I said in a previous post, you are wearing too tight underpants.
Your testicles are being pressed against your spine causing dizziness and headaches.
Castration is the cure.

Hello,

it seems to me that the problem is not only your car, but also your mechanics... They don't seem to know anything about the old K-jetronic injection system, they only mess with it. And charge you for their mess...

Your CO problem will be cured when you use your brains, and that is searching for the leak.

Please listen to the advice of the members, but if you don't listen, YOU only make a fool of yourself.
On the other hand, you are starting to become a person who gives the 924 a bad reputation...

Your headlights: first of all, HAVE THEM ADJUSTED!!!!!!!!

one other thing to check is that there is a rubber liner on the top of the firewall that will seal the area off from the firewall to the hood, if this isnt there then any fumes can go right into the cabin
