MAHLE Original GS33637 Engine Valve Cover Bolt Kit

Bolts are suppose to come with aluminum sleeve which it did not come with. These bolts will probably work for a metal/ magnesium cover but if you’ve got a plastic one they be correct and you’ll crack the cover upon tightening.

Got all of them in place and went to start torquing them down. First bolt dead center head broke off. Now I have to get a new set of bolts and try to drill out the broken one.Edit: My fault completely. Thought I had the torque wrench set to Nm but I had it set WAY too high. If this happens to you and you shear off the head... usually there's a little lip left on the torn end. Use a screw driver and you can back out the left in piece and use needle nose pliers to grab it. Cover any open engine ports so you don't drop anything into the engine.

If you're doing a valve cover job on an N52 engine with magnesium valve cover, these are absolutely required. Just make sure you follow the torque settings to a T. YouTube has decent tutorials on this, especially George Austers.

Not the very best boltmade out of cheap aluminum, must be very delicate when tightening them very easy to snap, ended up snapping two of them

It was as described in the ad but felt cheaply made. When installing them I was unable to reach the recommended torque specifications that was required by vehicle manufacturer, 2 bolts broke before I could finish stage 1 of the torque procedure. Due to the fact that I had no other bolts to use, I finished tightening the rest by feel and hoping it doesn't leak. Would not recommend.
