    Preparation for valve cover

    I would like replace the valve cover gasket. As it is leaking in the back around the bolts. And onto the exhaust manifold.


    I have the gaskets, and grommets for the job.


    I just wanted some tips to doing this on my vehicle.. I read the pelican parts DIY. They said to put the gasket on the block. Then put the valve cover on.


    But I asked my friend who's been working at BMW for 5 years. He said to put the gasket on the valve cover, and then put the valve cover on.


    Also. How are people torquing the bolt in the back that is up against the AC pipes? Not sure I can get my torque wrench on it!


    I just want to do it the correct, leak free way!!


    Thank you!!

    put it on the valve cover otherwise you chance it not seating into the grooves properly and leaking. You don't need to torque them. they bottom out against the head so just get them until it stops against the head snug. Its a very simple job. take your time and take pictures if you need to. first time should take you about an hour total, not including cleaning the valve cover out and cleaning the mating surface of the head etc.

      Whether you decide to use a torque wrench or not, make note of *inch* not *foot* in the torque spec.

            I put the gasket on the head first, to me sure it fitted correctly. Use a little sealent at the front corners at the timing case seams and at the two half moons at the back at the transission point.


            The special grommets are the parts that put pressure on the cover. The special bolts only press down on the cover/grommet by as far as they do.

            If hou have the cover off and just put in one bolt, you'll kow what I mean. Just bolt them down against the block by hand power.


            I then take a mini wrench and give it only the slightest of a turn, using my pinky finger on the wrench.


            Same in the M3. The head threads are known to strip very easily.

              That was classic. "Why do I keep snapping these things..."





              If the job has never been done before on this car, get a rubber mallet to gently tap on the VC to release the grip of decades of oil and hardened VCG.



              I did the rearmost nut(s) by feel. Most guys here say you can feel them bottom out and use just a tiny bit more pressure. I used an inch-lb torque wrench for most of them and by the time I got to the rear I had a sense of how much to tighten. It's light torque.



              Clean the channel in the VC before you put the new gasket in, otherwise you will still have some oil dripping out and you may think your new gasket is leaking.



              RTV on the edges of the half moons and by the edges of the vanos; less is more.

                Just did the valve cover. Everything seemed ok. Until I started the car. And it stalled almost immediately. And is now misfiring. . Help please. I made sure to be careful and do everything right.


                Update:


                I removed valve cover. Cleaned the surface again. Added silicon to the whole have moon opposed to the corners. And put the valve cover back on. Now it idles perfect.


                Apparently I put it on incorrectly, causing a vacuum leak.

                  yup i always do a thin bead of RTV around the whole gasket but most just do the moons. The valve covers warp over time and don't seal fully so i don't take chances. glad you sorted it out
