E30 325i Rag-Top 2956 Report post Posted April 1, 2009 The book says to do it with the rockers in place, but even with them backed right off, there are always 4 rockers under compression at any point, and I can't push back the rockers and pull the shaft at the same time, even with a helper or two! Is it not a good idea to remove the rocker shafts first, then the cam shaft? More likely to damage the rockers / shaft / cam lobes? I'm sure there is a wealth of knowledge out there on this....

melowpuf 19 Report post Posted April 1, 2009 I've always pulled the rocker shafts out first.. It would be very difficult otherwise, as your probably finding. Quote Share this post Link to post Share on other sites

topcat 11 Report post Posted April 1, 2009 remove clips that hold rockers. slid rockers off the cam lobes. 2-3 will still touch the lobes,rotate cam and slide out whilest rotating. time consuming. had better results,less fustration doing it this way. removing the exhaust rockers and shaft will be enough to remove cam shaft and half the 'rebuild' time cheers m Quote Share this post Link to post Share on other sites

Mark 178 Report post Posted April 2, 2009 Sorry to threadjack. But about how much would it cost for a mechanic to replace the camshaft and head studs on an M20... labour/parts included? Quote Share this post Link to post Share on other sites

TA DA!!!!! Excellent, done it, and a lot easier that I thought, once you get the pressure off the rockers by sliding them to the side the rocker shaft comes out pretty easy. Then the cam comes out no sweat!Cheers for the info, i was halfway there, but couldn't work the last bit out. Bimmersport to the rescue... Quote Share this post Link to post Share on other sites
