Hi all,

Curious to know, is the 11367831906 Plate from BMW reusable ? Reason I ask, Since i have replaced the 11367831906 from BMW, and have removed the 11367831906 3 times to fix things,

It is now leaking again ? your thoughts? Traveled 800 miles on it

TIS says to replace the sealing plate each time. The o-rings get compressed, so they might not seal if you reuse the plate. Beisan sells an o-ring kit and you can buy a few to have on hand if you don't want to buy a new plate each time it gets removed.

Got it. Gasket can go on ether way right? Or do you prefer the crushed side go towards the head?

If vanos top corner alignment dowels remained on engine head place vanos gasket on engine head.
Place gasket on head with gasket ridge to vanos (front). Gasket two lower tabs will point to vanos (front) (picture).

Only time I ever advocate using any sealant is around the lower left hole if there was previously a leak from that area. If so, use a *thin* layer of sealant on the head side. I use toyota fipg but hondabond likely works well too.

Should I coat the gasket in a thin layer of Honda bond?

Random question can you replace the vanos gasket without fully removing the vanos itself?


Sent from my iPhone using Tapatalk Pro

Yes, As mentioned above be sure to clean both surfaces. I use red 3M scotchbrite pad.

Don’t use anything too abrasive as the head is aluminum.

Remove the vanos solenoid plate, then just unbolt the vanos module, then separate it from the head about 1", then replace the gasket, and put things back in reverse order.

Technically possible, but you probably want to get in there and clean up the mating surfaces. If you just disconnect the splined shafts (and don't touch the sprocket bolts), you don't need to redo the timing.

How to remove that sleeve ?

[sapote]

I know the car can adjust timing my gut says this is close enough but my ocd says it’s not perfect.

What do you mean -- the software tool said the crank was not at TDC? or it said vanos timing was off? Setting crank and cam at TDC is not the same as saying vanos timing is correct -- it depends on the position of the vanos pistons at that moment.

[Mspir3d]

To avoid chain slack, always turn the crank CW in the last 1/2" or more to land on the TDC mark. The line between O and T is the mark you want to land on.

That’s about what raj had in his directions. The picture was without inducing any slack in the chain. I know the car can adjust timing my gut says this is close enough but my ocd says it’s not perfect.

[sapote]

I did the timing, rotated the engine and the cams line up perfect when the crank is between the 1 and O. I can move the crank back a tiny bit without moving the cams and it all lines up. Is this close enough or should I do it again?
