N52 valve cover gasket replacement
Hi all
Slight weep of oil means I think it’s time to do the valve cover gasket on the coupe
Q1- mine is a silver top engine, is that the one that needs new bolts or can I reuse?
Q2 while that’s off what else is worth replacing?
Cheers
Stuart

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 .

Just had a thought you may have different part numbers as yours is the silver top . Pretty sure you are supposed to replace the bolts on your engine though .

N52 valve cover gasket replacement
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.

If they are like the m54 ones you have to go some to break them and it’s usually when you apply twisting pressureBmw Enthusiast wrote: ↑Sat Mar 16, 2024 6:46 pm 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.

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.

Coupes because stunning!

N52 valve cover gasket replacement
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.
