Well, I guess it was inevitable. My car ran fine all year when I was at school, now it breaks down. When I started my car today while I was out running errands and I noticed a rattling. I thought it was the catalytic converter, as it sounded like it was coming from that location. I figured maybe a couple of the exhaust bolts were loose so I'll tighten them when I get home. One mile later down the road I heard a pop from the exhaust and it died. When I turned it over the exhaust would make a light popping noise every second or so randomly. I thought maybe a piece of the cat broke and it was clogged. After we towed it home I tried turning it over again. After a couple of tries it fired up. The familiar rattling sound was back, this time maybe a little louder. When I got out of the car I noticed it was coming from the engine. Opened the hood and it sounds like maybe the valves are hitting or maybe a spring broke. Through all of my valve issues this sound is new. Not the sound of a broken valve, or fragments of valve seals in the cylinders. I have no idea...compression test is coming soon.

didn't know if you thought of it but could it be a bad lifter...right now my car when i first start it up has a knocking sound under the valve cover...but after a minute it does away (i think its sticking)

I hope you can still make it to the Fest!

Woohoo or boo hoo?

Don't start it again until you find the problem.

:O
If worst case scenario rolls around, I'll probably be going through there on my way to the fest

Hope its something simple tho!!

I will NOT miss 944fest, no matter what I'll ride up with someone. I would like to have my car though. Last time I started it I noticed that it did have oil pressure, it just sounds like a diesel. When I get the compression tester tomorrow I will check it and see whats up.

Check the belts before you do anything man. Nothing really comes to mind on this one. Belt slipped a little and the valves are contacting the pistons?? Not sure man, good luck and keep us posted.

Damn. Hope it's something simple, quick, easy and cheap to fix.

I didnt know that was possible on these cars?

I checked the t-belt right afterward, it was still intact and had some tension on it. That's going to be one of the first things I check though. See if it could have slipped a couple of teeth. What kind of noise does the engine make if a valve spring breaks? Right now it sounds exactly like a diesel engine.

i hope this doesnt happend to me, the yellow has been making some weird screetch scratch noises recently

Serge944

Use a "stethoscope" and try to isolate the noise. Is it coming from the cam tower or the head?

I think it's just worn lifters. They can get very noisy, especially on start up.

pearldrum944

Worn lifters would have shown signs of going out though, wouldn't they? I had no sound problems with my engine except a slight ticking which is still there (from dropping a valve 1.5 years ago or so) I let it run for roughly a minute when I got it started and the noise didn't change.

Like others said about a stethescope... also check the crank case...

May be bad... my 924S sounded like it had a bit of a valve tapping, then about 150 miles later, oil pressure dropped to 1.4 while doing 75 MPH in 5th gear... Ended up being a spun bearing...

Best of luck my friend...
