The lifters being hydraulic need time to pump up. My wife's 93 525ia had the same issue. I switch to 0w-40w oil and the problem went away.
I have a 1995 525i- When I start my car in the mornings it runs rough until it warms up and then it purrs like a kitten. Any advice on why it would run a bit rough from a cold start?

get some Auto-RX... and check for intake leaks when cold.

It's a pity to attach back to the throttle body. The excessive heat turned the rubber in crap. It's part 5 on the picture..
