Description How to time a BMW 540tu engine, part 1. Should have used a script, just winged it. One part was repeated twice, should have edited it out. First video, not ready for prime time yet.
Never saw any instructions to do bank 2 first. All of the ones I’ve done the chain has always been tight on both sides. Never had a code after doing them.
@@bmwinfo7764 I've seen it in Beisan guide. I'm just retiming mine, because my mechanic was changing guides and timed it bad, engine is running but very rough idle, and no power, got error 34 Function, inlet camshaft control, bank 2, and live data from CPS reads bank 1 = 0°cr and bank 2 = 42°cr, adaptations angle on bank 1 are from 0 to 4, and bank 2 are all cylinders same -20. So there's probably bad timed inlet camshaft, over advanced from what I've read on forums. Doing it now by myself to get it everything done properly. Your videos and posts are very helpful exactly to the point.
@@bmwinfo7764 just reading page 134 chapter locking of engine timing, quoting: "Tighten bank 2 then bank 1. Note: This assures any chain looseness it drawn to chain tensioner."
If you have the crank pinned at TDC on the compression stroke you should be able to turn the cam enough to put the cam lock blocks on. Join the E39 forum at bimmerforums.com
@@bmwinfo7764 Thanks. I'm doing the chain guide job without changing the vanos. All DIY's I could find for this job, include removing the sprocket, as they all include repairing the vanos. I'll leave the sprocket for this matter, but I suppose loosening the sprocket would be necessary when setting the correct timing, to be able to retard the vanos cylinders?
@@ThePerfectionOfLexus you’ll need to remove at least one sprocket to get the chain off so you can replace the guides. I sell rebuilt vanos with new Beisan System o-rings.
