Engine noise/rattle when starting up?? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

My 986 and my father's 996 are both rather noisy for a few seconds after initial start-up, and there is nothing wrong with either car. I believe the sounds you're referring to are perfectly normal. Out of curiosity though, what oil are you running?

Padawan, but do your cars make this noise when warmed up and occasionally can be heard whilst driving - like a rattlesnake sound but how you would expect with metal parts rattling. Not sure about the oil it was replaced last June/July should I attempt to put some newer oil in?

IMHO, it wouldn't hurt to change out the oil first using Mobil 1 (0W40)....9.25 quarts.

Keep us informed.

Good luck with that.

good call. I had alot of lifter noise in my old 944. When re-did the head I made the cam followers too tight. The Mobile one cleared it right up. Might help here.

Yep, I'll give the oil a change. May try it myself next weekend or ask the garage to do it this week - I need two new sidelights anyway. I'll keep you posted. Cheers

I'm not sure taking your Wait & See approach was the best decision. Your engine is making noises where it previously did not - it's telling you something's not right.

These motors can cost upwards of $10k to replace, alot more than a couple hundred bucks for a qualified mechanic to look it over. And soon as possible, don't wait weeks before taking any action.

Seeking advice here isn't your best bet either. There are lots of knowledgeable people here, no doubt, but they haven't seen the car and have only your rather vague description to render a guess on.

It may be nothing, and I hope that's the case. But, if it turns out to be something, you're much better served by addressing it sooner rather than later.

My advice is to have it looked at and don't drive the car (or at least drive it very gently) until you do. Good Luck!
