Valvetronic motor gasket replacement

Ilogik · Post by **Ilogik** » Wed Mar 27, 2024 2:18 pm

Pretty certain I've got a leak around that area, I was wondering if anyone has any recommendations of someone to do it in the Midlands. Could do with getting this done before getting oil / filter change done.

Its not a big job something I did myself. Remove the surrounding bolts, then wind out the motor using an allen key (count the rotations), replace the gasket, replace motor (wind back in counting again), replace surrounding bolts.

I managed to not blow anything up

but maybe one of the more mechanically minded on here has a proper guide!

Where are you? Norfolk probably a bit far but bigwinn is in Lincoln

Also, N46 or N52? On the 6-cyl you just unbolt and lift it out. No winding to do.

With the N52 you have to unwind the valvetronic motor to take it in to service mode to remove it.

Did mine on a N52, fairly simple job and some great how to's on line. Did have to wind the motor out and in again. I didn't need to electronically reset the motor. Just cycled the ignition a couple of times and all good.

Cant speak for everyone else but when I did mine I rotated the motor clockwise with an allen key counting the turns until it bottomed = X.
Wound the allen counterclockwise whist disengaging the motor and again counted turns. Y
Without rotating motor whilst removed - refitted - winding motor clockwise same number of turns Y until it was home and bottomed.
Wound motor out to original position X turns.
Use an OEM / Mahle gasket you should be right.
(Mine was N52 3.0si)

You 100% need to wind it

As you remove the motor it WILL rotate.
Better safe than sorry.
Put things back the way you remove them - in my opinion or you may wish you had.

Each to their own.
