N52 valve cover gasket replacement
- Thread starter bigwinn
- Start date
Q1.
I didn`t change mine and I have the black top so either I should have or you need to
Q2.
This is what I changed when doing mine .
Valvetronic Gasket 11127552280
Gasket 11127559699
Eccentric shaft sensor 11377524879
You are also advised to get a spare one of these 11157559528 as they are prone to braking when taking them off but mine didn`t brake . It depends if you need the car before getting a replacement if required .

About to do my N52 with the black cover. Research indicates that I don't need to replace the bolts. They are captive on the valve cover. See the other recommended part above is the crank case breather pipe that runs from the rocker cover. Can this be changed with out taking the inlet manifold off? Any thoughts welcomed thanks.

I'm replacing the whole cover too with a Febi Bilstein one, but no pipe with mine. Will just have to be very careful when I disconnect it.

Ahh, thanks. Will be careful. Planning to do it later in the week. Thanks for the tip.

I'm pretty sure you need to replace the bolts on all N52 engines because they are aluminium "stretch" bolts.
That's so they match the thermal expansion/contraction characteristics of the Magnesium/Aluminium block and head, which steel bolts wouldn't.

The previous owner of my 330i with the N52 had a new cam-cover gasket fitted just before I bought it by a local garage, but told me he had insisted they used new bolts.
The invoice includes the comment "Found front O/S corner of rocker cover had 2 bolts snapped off and been left in holes" so they had to drill them out!
Shame he didn't get the oil filter housing gasket replaced though.

In the past few weeks I’ve done an E89 and an E85. Both black top. Both had magnetic bolts so not ally and I reused them. Although captive, some of the captive collars come out with the bolts. Note which are which as the corner ones have a slightly bigger collar and won’t fit anywhere else.
