I believe the alternator comes out. https://5series.net/forums/diy-do-yo...i-545i-120107/

Not sure if replacing those spark plug tubes are "necessary" or not. The shop that did my VC job said it was, which was why they ordered new ones. It's not much more involved since it's part of the removal to get to the VC. They're about 20 bucks a pipe I believe.

In all honesty, my oil leak problem could have been solved with the oil pressure switch (cheap), vacuum pump (pretty cheap), alternator bracket, upper and lower timing cover gasket (all at the same time, not that cheap. $700 at an indy).

I ended up getting the VC changed when I didn't need to. And just doing 1 side ran me about $1000-1100. So if you have an indy that will do both sides, and the upper and lower timing cover, might as well do the alternator as well and if you can get away with $1500, that's really cheap imo. Guess it's also relative to where you live. I had all of my work done in the Bay Area.

Replacing the alternator bracket o-ring requires removal of the alternator and the driver side engine mounting bracket. A real pain. The upper timing cover gaskets are easy to replace if the valve covers are already removed, I don't know why they would charge another $500 unless they were talking about the lower timing cover. That requires removing the heads.

What are the exact torque specs for VCG and timing cover bolts
I do not have Bentley manual and it does not say in TIS online

Note: The Valvetronic motor must first be removed in order to remove the cylinder head cover. The eccentric shaft must be in the minimum lift position and the motor must be wound out from the eccentric shaft. The worm gear could otherwise be damaged when separating the worm shaft and the worm wheel as the eccentric shaft springs back (due to the torque compensation spring).
If it is not possible to remove the motor, due to mechanical failure or sticking, the worm shaft can be moved using an Allen key to release the motor. A hole must be drilled in the rear plastic motor cover in order to access the motor shaft (worm shaft) using the Allen key. The motor can then no longer be used.
What does this mean in simple terms? Have anyone removed it without damage?
Thanks

The VVT motors come out easily. Just remove the four screws, then spin the motors out. They have a worm gear that engages with the eccentric shaft gearing, so they will spin right out. Installation is the reverse of removal. When you are ready to start the engine, turn the ignition on and wait a minute or so for the VVT motors to initialize and move the eccentric shafts to where they need to be. Contrary to what my indy mechanic told me, no you don't need to initialize them with INPA.

So all I need is to remove the 4 bolts and then just pull it out? What do you mean by spin the motor out? Just wiggle around or pull it up straight? I think the valve caver gasket kit comes with VM gasket also or do I have to buy it separate?
Thank for helping me out

I think it's like taking out a screw. Kind of "unscew" it.

Stephen Max

You unscrew it. Google "worm gear" and you will understand.

How did you make out with this bro?... I just did the alternator bracket gasket now Im thinking about tackling this.

Margal

I decided to fix all the oil leaks and the same time do complite cooling system refresh including valley pan pipe once i take the cylinder covers off. still learning, getting nessesary tools, parts and waiting for the weather to get warmer to works outside. I think this gonna be a two week project for me.
