Start Up Rattle

OK, I've been using the car a bit over the last week or two, and great as it is to drive, I definitely have a rattle at start up.

It lasts just a second or two, and only does it when cold. when it's up to temperature, nothing at all. Getting irritating now so can anyone shed any light on it,

I dont believe it to be IMS

related, I changed the oil and filter a couple of weeks ago and had a good look at the filter and bowl. both were spotless and showed good clear oil that had only done about 3000 miles. No oil at all under car or on bottom of engine. In short, no obvious signs. Oil is Mobil 1 New Edge 0W-40

Car runs beautifully and it's just annoying to keep hearing this every time I start it

Leads me to tensioners/tappets or something. Is there a fix to this, ie , can I adjust the tensioners or do something that will not involve major teardown.

Thanks Guys, all input greatly appreciated
 
Sounds pretty normal to me. Lazy tappet, which takes a second or two to pump up. Try a 5W-40. It almost eliminated it on my 996C2.
 
Hi Richard,
If it's normal..good..I can relax about it. Having just put in 90 quids worth of mobil, It'll have to stay for now. Did look at a 5-40 but couldn't decide on best brand, so went with recommended. what oil do you run ?
 
I used to use Fuchs Titan Supersyn 5W-40 which I bought from Opie Oils, but my indy now gets a very good price on Mobil Synt S 5W-40. Both are on the Porsche Oil Approval List.
 
Not uncommon on these or many other engines with Hydraulic Tappets, if they stand a while ( sometimes only a few hours ) they can take a few seconds to fill
