Valve Clatter

[500]

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?

I just went through the same experience last weekend when I went to pick up my car from my indi shop. I left there for a couple of weeks to change out my control arms, alternator, and do a 90,000 service. The shop owner said that is like a new car now after he changed everything. When I started it up and listened, I heard the clattering noise. I asked him about it and he said "Its the lifters" when he said that my heart sank. But he laughed and said that because the car had been sitting for two weeks all of oil drained out of the lifters. He said to drive it a few miles and it will pump up the lifters.

I went for a 5 mile drive and sure enough, no clattering noise. I have not heard it since.

Hope this helps.
