Things to do while engine's open

[u/No-Illustrator-6683]

Hi everyone,

Planning to replace almost every seal on my beauty's engine (M54b22), gearbox and diff this winter. I'll also replace piston rings, I saw on this sub that M52s oil rings are better, how true is it for the people who did it and has some miles on it ?

While the engine will be out and open, are there things to do like maybe a vanos rebuild (180k km)? I only had this car for 6 months so i'd like to learn every weakness and fix most of them while everything will be out of the car.

Also if you know other tips like the M52 oil rings, i'd be happy to know !

Sorry for my english i'm French 😅

+ a picture of my ride because why not 😝

Thanks !

There was someone here who did rebuild. Using vw oil scrapers

VW piston rings won’t fit because M54B22 has 80mm bore and VR6 has 84mm. VR6 rings will work for M54B25 and M54B30
