Don’t pin me down on it but I believe to have heard that this lead to failure in some cases.

An Indy shop wanted to do this when i asked about bullet proofing the vanos, I also saw a video or a post somewhere that shown some carnage with with sleeves coming out. I didnt go through with with that shop ended up taking over kaiv to get my vanos refurb done.

17 reactions | This is a BMW S54 Vanos Oil Pump Disc ‘fix’ we see very often from another UK BMW specialist. The crude inserts generally break up and fall into the engine - when we do these, we re-machine the disc for a lifetime of service - a proper repair without the use of inserts.

Yeah, don't do the sleeves. I've come across a couple of Vanos unit's done like that... little pieces had broken off the sleeves where the tabs mated to the disc and of course, the bits had then gone into the engine 🤕
