Sounds like a broken rocker. I remember seeing a video on youtube or something a while back of a e30 sounding like a subaru, i think it was a broken rocker arm so yea.Comment

Broken rocker is most likely.
Just pull the valve cover off and have a look.Tenured Automotive Service Professional - Avid BMW Enthusiast

what do you mean sounds like a subaru, that is really an odd description of a soundYour signature picture has been removed since it contained the Photobucket "upgrade your account" image.

If you want to make it a long, cumbersome, draw out process.... you can change it in the car.
I much prefer to pull the head to do it. It doesn't take long and you can replace worn seals and the like while you are there.
I prefer to pull the head with the intake manifold and exhaust manifolds still attached. This saves you alot of time, labor, and the cost/time of replacing those gaskets. The downside to this is the entire assembly is pretty heavy and although you can likely lift it up and off, and hold it at your chest fine.... holding it with your arms stretched out trying to lower it steadily onto the block to put it back on is near impossible. With a friend on the other side to help its cake.
Do yourself the favor while its out and replace all 12 rockers with new ones. You'll never have this problem again. They way it sounds like you like to drive, with these rockers age, they are all just waiting to follow suit.Tenured Automotive Service Professional - Avid BMW Enthusiast

Yes, there are stronger rocker arms - do a search here and you will find them. Not sure they are really worth the extra $$ unless you are going mad forced induction though.Current Cars2014 M235i2009 R56 Cooper S1998 M31997 M3Comment
