BMW: "Hello BMW Parts..."
Me: "Hello. All the rubber hoses, gaskets, and o-rings under the hood of my E46 are falling apart" BMW: "Yes, they do that. Which parts would you like to order?" Me: "All of them" BMW: "Done"

For those wondering why all the work replacing stuff - here's a shot of the vacuum hoses going from the manifold to the secondary air pump check valve. This is pretty typical of the condition of all the hoses under the hood:
Redoing the Vanos tonight. Before and after beauty shots. At one point my wife asked what I was working on. "Vanos: The Cams of Fate" I said. She just kind of look at me. "I think you need some fresh air." Yeah, I've probably inhaled too many VOCs tonight.

Glad you didn't break the left-hand threaded cam bolts.
Rajaie at Beisansystems.com makes a great product. Did mine in February 2008 (thread HERE) and haven't had a stumble, cold stall, "hiccup" related to Vanos seals since. Nice progress. |

I most strongly reco that you replace the crankshaft sensor on the driver's side of the engine, under the intake VANOS Solenoid (Gray wire bundle) before re-assembly of the VANOS and the Oil-Filter Housing. These go out and will send you back to "GO" right after assemble.
Is that a metal impeller water pump I see? |

Its a new BMW pump, so composite impeller.

The composite impellers on these water pumps start to die on these cars after awhile and thee pumping efficiency degrades. I put a metal one in mine 6 years ago and have had no issues since - including rock solid temps on hot track days. Just an idea.

I read somewhere that BMW used plastic impellers, that over time would become brittle and crumble apart. They've since switched to some kind of more durable composite, that's superior to the plastic and doesn't suffer from the same problems. I also went with OE composite pump when I did mine a few years ago. Nice thing about E46, is the water pump is very easy to access and swap out.

In theory at least a busted plastic impeller isnt as likely to damage the housing or other aluminum bit as a metal one is. Of course could still black a water passage, I think each has its positives.

replaced the oil filter housing gasket in the 94 this weekend also...hardest part was getting the alternator lined up as I chose to not remove the fan...lets see if that stops the oil showing up below the rear main seal...
That is a heck of a lot of parts...car is going to be a happy drover knowing it fell into your hands...well done...would say keep it up...but don't want you to keep forking over the bucks...smile
