Well if you have worn valve guides or hardened valve stem seals, what happens is that overnight some oil left on top of the engine, in the cylinder head, drips down past the valves and the seals (which it normally should not do) and then collects in little drops on top of the piston.
So you start up first thing in the morning, and your spark plug momentarily fouls due to the oil on it, and you'll get a few puffs of blue smoke. Once the engine runs for 30 seconds or so, it smooths out and the smoke disappears, because the oil has burned up.
Can oil still drip from the valve stems while you are running around town?
Yes but only under conditions of "high vacuum", which generally means letting off the gas while in gear and letting the engine drag the car's speed down---then, when you step on the gas again,----POOF!---another quick burst of smoke.

I dont think the odor is sulfurous. I'm going to have it checked out, just to play it safe. Winter is right around the corner and I want my car running smoothly when the snow finally starts here. I'm just curious, why would it be rough just on start up, but not when I'm driving it?

What exactly will my mechanic do to check this issue? And if this is the problem, is this a pretty expensive repair?

If you wanted to check for worn valve stem seals or valve guides?
A cylinder leakdown test tells you a great deal about the internal condition of an engine.
Generally on a car as old as yours, you live with it. It can be an expensive repair (the valve guides themselve I mean). Replacing just the valve stem seals is a lot cheaper to do, but on an older engine, perhaps not as successful.
If you aren't seeing lots of blue smoke on start up, this is probably not your problem anyway.

I havent seen any blue smoke, so maybe it's just the EFI. I think I can just live with it. I do have a questin about the washer pump fuse. Is it just one fuse or is it two? Can you tell me if I can use regular ATC fuses or do I have to have special fuses for it? Can you tell me what amperage I need for the fuse? Thanx

Also is it wise to have the oil changed? I bought the car from a private seller and I have no idea when and if the oil was changed...If the answer is yes can you tell me what kind of oil, it does say 5w30, but would that be a sythentic oil? I appreciate any help, Thanks again

If you have no idea when the oil was changed I recommend you change it ASAP but first you should check with the dealer to see if they have that information. Also you should acquire an owner's manual from a dealer, if it did not come with the car. This will tell you what type of oil to use and how to interpret the service indicator lights (those green dashes that come on when you start the car).
You have enough questions and enough problems that I strongly recommend that you locate an independent BMW Specialist in your area (after acquiring a manual and service info.) ; bimmers.org will give you that information. These cars can can be expensive to maintain at dealer rates but they are reasonable at most indies but regular maintenance is a must.

I had the washer pump fail on my 1997 5er. It's an easy -if a bit fiddly- DIY. It took me 45 minutes to R&R the pump.

#2408 of 2735 Help! Need a 3rd Windshield Replacement
Nov 20, 2009 (6:25 pm)
I am facing the THIRD replacement of my windshield on my 2007 530 wagon.
Here's what happened:
August: rock hits and cracks windshield within driver's sight.
October: Windshield replaced by bodyshop with BMW parts - no problems with fit but windshield has blurry spot in middle and is defective.
November: BMW shop that sold the defective windshield replaces it under warranty.
This week, I drove took car on the highway and it has so much wind noise it seems like the window is open. BMW shop #1 says that the BMW shop #2 that did the work did a really bad job. I can see black stuff oozing out on the sides and the mirror is not lined up right.
So, I took it back to BMW shop #2 which did the work - they apologize and agree the work is bad. Car needs to go back in and windshield needs to come out again.
Question: It seems like I am stuck with the shop that did the bad work. Does anyone think I have any recourse to get BMW to pay for the windshield somewhere else? I am not wild about using this dealer. In fact, I am not so sure the current installation is even safe.
Thanks for any advice.
