BMW E46 M3 Vanos bolt failure #2

2002 BMW E46 M3 SMG with 83K miles

I was made aware of the vanos bolts being potentially loose on the intake side, so I decided to check mine.

Well they were loose and upon further inspection and removal 5 of the 6 bolts were sheared off and the 6th bolt was half sheared and just about ready to shear off.

Had that happened the vanos gear on the intake side would have come off inside the engine and probably destroyed the engine internals.

VANOISE was BMWs biggest failure. Sold my E39 540i because it ended up sounding like a diesel.

@molliarti VANOS varies the timing of the valves by moving the position of the camshafts in relation to the drive gear

how did you get the bolts out?

this is scary shit, i also have a 2002. Did you fix it and car runs fine since?

I have an E46 330i and the only performance item I have is the Signature Motoring performance CAI for about $160. The performance kit adds around 13.5HP on the dyno, sounds freaking great, and installs in under 30 minutes. Highly recommended.

-13.5 HP increase

-Lifetime filter

-SOUND AWESOME

-30 min. install time

Aside from the power gain, the SOUND is amazing at higher RPM but sounds normal in regular driving. I’m thinking about added high-flow exhaust next.
