Also listen for lifter noise at this point & decide if you want to replace lifters while doing the Vario-Cam chain wear pads need to be replaced also (4) this requires removing cams, pads could be contributing to noise, good news is they are cheap. IMS bearing & RMS ! You will notice once you have things apart it is fun to replace parts so inspect everywhere & if anything is showing wear buy new parts then. Water pump unless you have replaceed recently, same for motor mount. OK when you can tell us how you lost your license mate!  |
I seem to remember reading that If you switch to the new style tensioners, that you need to replace all of them. I can see where you should replace the IMS and bank 1-3 since they both are on the same side of the IMS. But since the 4-6 tensioner is completely on the other side of the IMS, I can't see how not replacing that tensioner could have any effect.
