On my 450 SL (99,000 miles) I had a moderate oil leak, I just replaced my valve cover gaskets on both sides and what a big difference on the oil leak....just about all gone.

My question is that when I was taking my passenger side valve cover off I accidently bumped out of place the oil fill tube. I think I put it back on ok....but now it seems that there is a light tapping sound coming from that side the first couple of mins. after I start the car....it then seems to go away. I don't remember the sound before....

Did I do something?

What should I look for?

Thanks in advance!
Mike
