had the car for a month now i got oil change like 3days ago and it made the noise at the shop. I took it took her to a BMW Specialist shop. the oil in there is 20w50. im not sure if its too thick that the lifters not getting enough pressure because seem to me it does it when its cold, like in the morning.

I think 20 weight is too thick. Did you read your "Owner's manual" ?
What is the recommended oil (per your manual) ? I would recommend
changing the oil to may be 10W or 5W (or even 0W if using synthetic).
Asking opinions on what weight oil to use is a never ending saga. I use 20W50, valvoline, and I am in Los Angeles.
However, I think regardless of the weight, there should be no problem in gettin oil to the lifters. They might be oil starved for 2 seconds at start-up, but if you are not getting oil to the lifters, I don't think a lower weight will help that much.
You need something to clean them with - and, like I said earlier, I tried Risolene (yellow bottle, 1 quart) and added that to my crank case. I think it helped tremendously.
i lived in australia now... used to live in the US.. yea it do get hot down here.. even our winter is like america spring temp. our summer get dessert hot like arizona and such.. so i reckon they know what they're doing with 20w50
hmm 0w40 ok i give that ago.. i think the weight is a bit too thick for the m40 cyn 1.8 anyway.. but im not so sure because australia could get really hot even for its spring and their winter are still warm.. :|
