Car Forum / Porsche / Porshe 944 / February 2004Rattle on acceleration
When I accelerate (mainly in 1st or 2nd gear, it seems) I get this light- sounding metallic rattle. It sounds a little like the noise I remember as a kid when my dad's Ford Cortina had "rattling tappets". It's difficult to tell where the sound is coming from, probably the front of the car from what I can make out. The noise does not occur when revving whilst stationery - at least, I haven't managed to get it to do so. Any ideas, tips, etc... very welcome.  SignatureRegards, Dave dave_ryman@hotmailNOSPAM.com http://welcome.to/daves.website http://travel.to/formula.one I have the exact same problem. I know this doesn't help, but know you are not alone. I thought it was an exhaust hanger (had a similar sound on a Jetta once) but that wasn't it on the Porsche.

I just pulled it off. The back side had split and it was hanging form the cat. Chip > > I have the exact same problem. I know this doesn't help, but know you > > are not alone.

Smoke everywhere today! The smoke looks like it's coming from the area where the exhaust down- pipe joins to the exhaust pipe. I don't think it's an oil leak putting oil on the hot pipe, because it's not got that bluey hue, and doesn't smell right. I thought it might be a leak in the exhaust, but the smoke is too cloudy (the car was hot) - and it's not noisy. It smells like burning rubber or plastic, so I'm a little worried that something has gone astray: However, the car still seems to run fine, so that seems like an odd explanation. Anyway, it's up on the mechanic's ramp tommorrow, so I'll keep you posted.

A quick update - got the car to the mechanic this afternoon - it's an oil leak. Good job I had a fire-extinguisher at the ready!! Interesting thing was that the rattle has now gone - may be connected? Who knows.

Well, it was a ruptured oil seal. Thankfully, the bill (including labour and VAT) came to a modest ?120 - phew!
