Haven't been driving the C2S much lately, been taking the lazy man's route using the auto box BMW instead. Last night I wanted a more spirited drive so I took out the Porsche and upon start up there was lots of valve clatter which continued until I drove for about a mile and it went away; when I drove the car this morning there was no clatter at all but I noticed I was down 2 bars of oil which I've already filled. I hadn't driven the car for about +/- 2 weeks.

I have noticed a similar situation with the BMW when I dont drive it for about 2 weeks or more and BMW's local Service Director told me its oil bleeding out of the lifters over extended periods of time and they silence once they get pumped up again; I was skeptical so he started a few other new cars that have been sitting on the lot for a while and most of them exhibited the clatter which went away after a few minutes. I never experienced this issue before with any of my Porsches and am curious if anyone here had the same issue?

 

Normal, and if I'm honest some times you can let the thing idle all day and it won't pump back up, you need to drive it. If it happens after sitting say over night or two days, that when its a bit excessive and your dealer could address it. But a week plus, no worries.

 

Thanks
