As you can see the urail was on its way out and just matter of time for the others.

Yes, thats true. If the u-guide breaks it takes the rest of the other guides with it. When i first read about the chain problem on these cars i got worried, so it is going to feel nice that they are all good. 😄

New primary, upper chains and guides replaced. I have also changed the guide pieces and o-rings on the upper tensioners. Now for the timing bit. I have had all camshaft sprockets free rotating, so i dont have any chainslack anywhere. Both vanos units are fully retarded counterclockwise to the left. All 4 camsprocketbolts are snugged up and ready for final tourqe. Have i missed something? Have a nice weekend 😄

I have removed it and put new silicone on both surfaces before i put it back. I know im taking a chance at getting a coolant leak, but if it holds i have saved some money. I dont find it that difficult to remove the intake manifold.

Removed tdc pin and cam blocks. I was going to crank the engine a couple of turns, then realine the timing parts. Then i saw the intake camshaft making some weird moves. Is this normal? The vanoses are empty on oil, is that was causing it?

The Intake Vanos does flip back due to its ability to retard and advance. When you are turning it it should be done manually to make sure you have not interference. Basically turn the engine with a big socket and bar.

Ive posted a video in my last post. It is what i have done rotated the engine by the crankshaft. On every full turn 360 degrees of the crank, the intake camshaft on bank 1 does a little jump/skip. After i rotated the engine a couple of turns, i loosend all the camsprockets again and set the timing with the camblocks, and retarded the vanoses again. I hope i have done this right. The chain tensioner is turned in by hand so much that i dont have any slack att all in the chain. Is that correct?

I havent cranked the engine with the starter motor, i have used a socket and a ratchet? (Those clicky bars you put sockets on), and of course the strenght in my arm😄 sometimes the english get a little messed up, hope it is understandeable 👍
