BMW E46 Valve Cover Gasket Replacement
Video tutorial on how to replace your BMW E46 3.0 litre in line 6 cylinder
engine's valve cover gasket. Process is fairly straight forward but does
require a little bit of know-how and prep work and METICULOUS care in
disassembly. When your valve cover gasket begins to show signs of
"sweating" or leaks then its time to replace the gaskets. Even if your car
has very low miles like mine does the age of the rubber seals gradually
deteriorates to the point where you just need to put new parts in.

In this two part video series Otto will show you how to replace the valve
cover gasket on the M50, M52, M52TU, M56, M54, S50, S52 and S54 6-cylinder
BMW engines. These engines have been used in various 3, 5, X and Z models
from the early '90s through the mid '00s. Note that while these procedures
are shown on an E53 X5 (00-06) BMW with the M54 3.0 engine, they can also
be applied to the E36, E46, E34, E39, E60, E85 and E86 3, 5, X and Z
6-cylinder models. Some will look slightly different or have slightly
different hardware but, the basic points and procedures are the same.
Part 1 - Valve cover removal steps:
In this video we will remove the valve cover on a BMW 2002 3.0i X5. Part-2
covers the installation.
For a list of the parts and tools used, see the accompanying BLOG post at:
1) Some models require that the cowl HVAC (Heating, Ventilation, Air
Conditioning) air inlet tray be removed in order to allow full access to
the engine valve cover. This E53 X5 does not require removal of the cowl
2) Remove the engine trim cover. Pry out the two round trim plugs on the
trim cover. Remove the two 10mm nuts or bolts. Lift the plastic trim
cover off and set aside.
NOTE: This earlier "coil on plug" model has the coils secured into place
via studs and nuts. On these models, remove the two 10mm securing nuts and
pry the metal harness clamp upward to release the harness plug. The coil
can then be pulled up and removed. Later M54 engine used the later "pencil
style" coils. These coils do not have any bolts or nuts securing them in
place. They can just be pulled up and out. See the "pencil coil"
replacement video at: http://blog.bavauto.com/go/coils2/
3) Release the securing clips and pull the harness plugs from the ignition
4) Remove the nuts or bolts securing the coil frames to the valve cover
and pull the coils up and out. See note above if you have the "pencil
coils" that do not have nut or bolt securing hardware.
5) Unclip the coil plug harness assembly and set aside. Unclip the oxygen
sensor harnesses and set aside.
6) Remove the valve cover securing nuts. Loosen and remove in an
expanding spiral pattern, starting in the middle of the valve cover.
7) Gently remove the valve cover. Be very careful if applying any prying.
this can easily crack the plastic valve covers.
8) Clean the cylinder head gasket mating surfaces with brake parts cleaner
and a clean cloth.
Now, click on to Part-2 and continue with the installation of the new valve
cover gaskets and replacement of the valve cover assembly.
