Hey everyone, I was hoping someone could help me out with a part number. I couldn't find it on Realoem. I was doing the Beisan Vanos Seals procedure and I was finishing up and tightening the exhaust cylinder cover on when one of the bolts snapped. I was wondering if anyone knows the part number for these bolts. I think they are around M5x25, but I am not sure. Any help would be greatly appreciated. I also contacted Raj from Beisan, but he hasn't gotten back to me yet.

It’s torx instead of hex, but otherwise identical -

What? Hex key size is not indicative of fastener diameter.Originally posted by Robert's_BMW View Post

That is very true, lol, I must of had a stroke when I typed that. I just measured the diameter of the bolt and got 5.75, so I am guessing M6 is correct.Originally posted by jbfrancis3 View Post2004 M3 Coupe - Imola/Black | AA Supercharged (432 whp / 275 ft/lbs) | ARP Head Studs | ACL | Besian | Mishimoto CC | AA Headers w/ 100 Cell Race Cats | SS Section 2 | OEM Section 3 | TCK DA 400/500 | TMS Rear Camber Arms | Apex Arc-8 18x9 / 18x10 | 996 Brembo (In-Progress)Comment

Yeah they fit my car fine. I ended up replacing all 6 just so they're all torx. Also for whatever it's worth, the other vanos bolts (which actually do have part numbers in realOEM) are also torx now if you were to order them.Comment

How did this happen? The torque on these is basically nothing for a reason I guess.This is my Unbuild Journal and why we need an oil thread

Yea, its only 7 ft/lbs. Barely anything. The other bolts torqued fine, this one just snapped.

Yeah I snapped one of the bolts that holds the VANOS to the cylinder head when torquing it. Same grade as the one you snapped if I'm not mistaken. Maybe someone had overtorqued it before and it snapped this time, who knows.Originally posted by Robert's_BMW View Post2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal
