When I start the engine for the first 3 seconds the engine rattles. Is this somethink normal or shell I expect something bigger? Cheers

I assume it's normal, because mine makes the same sort of noise for the first second or so after it starts up.

I actually think the "mechanical noise" that the engine makes on cold start-ups is charming and intoxicating all at the same time.

hahaha i like to see a positive in any situation.

my S makes the same 'chatter' for 1-2 seconds, i never rev through it, just let it deal with its issues, but im in North east of Scotland so we are colder at the moment, atleast its dry.

I would think it is just oil finding its way through the motor. Mine does it too... but I rev it to redline and hold it there for 2 minutes...... just joking. The noise goes away after a few seconds.

My 2001 boxster with 100,000 mi rattles also, buyt not for 3 seconds. I timed it it last 37 seconds. It then disappears.

I do have another rattle in the catalytic converter that continues. I know its the converter because I put a stethoscope to it. When I was a kid, I had a 944 that had the same problem. Turned out to be an oxygen sensor cap in the catalytic converter. I hope this is the same thing.

Try turning the key on for a couple seconds before starting. I learned that on a 996 forum.

My 97 does the same thing if I let the car sit overnight. I will try the "Key" trick of turning the key to on before cranking the car over.

Please let me know if it helps.

[wtf]

Ive experienced something similar on my car, i was freaking out after reading all this "IMS failure" ..

Ive only owned my boxster for a week and a half and the other day it just made a quick rattle on startup (like a clunking sound similar to a big end bearing noise - metal on metal clackering), but the noise goes away after a few seconds.

I turned the car off and on again and the noise didnt re appear. The car makes no other weird noises and drives beautifully normally.

Tonight I had been driving around with no incident, then stopped car.. An hour or two later i started it up again and got that loud rattle.. The noise sounds really disconcerting to say the least, and it went away after a few seconds.. I turned it off/on.. no noise.... off/on... no noise... off/on... a bit of a rattle again that went away after a few seconds..

The car in this occasion was not cold, the weather isnt cold (maybe 11 degrees celsius), and the oil level in the car is good...

im hoping theres nothing stuffed with it, and hopefully it isnt the sign of the dreaded 'IMS' ?

I worried about mine too until I drove a brand new Carrera S and Cayman S at the dealership and they both made the same noise on startup.
