quick off the thread but is there a newbie introduction page to the forum? would like to post my experience so far.
keep up the good work, that's every one on the forum, not just williamx5

Thanks!! Welcome!! I'm not sure about a newbie posting... Something to think about if one doesn't exist...
The search function works really well... A few key words and it should get you to the posts that you need...
Enjoy!!

I have used torque wrench for years, but when I just re did my M62 I learned that I needed to do things differently. You weren't clear as to whether you used the right tool or not. If you didn't, I would recommend doing it all again per the factory instructions.

Good day... Let me first say as a disclaimer that the work I do here is just me wanting to share all I do and love with BMW's and how they work... If you follow in my footsteps and rebuild your N62, do so with the methods and procedures designated by BMW as to be accurate... This posting is also not going to turn into a debate with how some do it this way and how some do it that way... This is how I am doing it... I will say that I was NOT using a degree wheel for the 100*... I guesstimated... Slightly past 90* is my unit of measure, but I did that with a lot of "CDO" (which is "OCD" in alphabetical order as it should be).... With each guesstimated 100*, I adjusted the torque wrench to see if it would click at the new number... I had 10 tries to get to an approximate torque value... I do understand TTY bolts and the such, but I was just curious to how close the bolts would come to a specific, uniformed torque value with this method... After all, if the initial inch-pound torque wrench is inconsistent, that degree of difference multiplies exponentially (or does it?)...
Additionally, where it really doesn't matter too much with two bolts holding a cap in place, the head bolt pattern is very different... I will go over this in far more detail when I get there, but I experienced a huge difference in torque value between the head bolts when I did my 2001 540i 4.4L... If you just tighten to 33 ft/lbs, then do 100*, then do another 100*, all three steps in the correct sequence, I found the first four bolts tightened were of a significantly lower torque... I discovered that if you leave all head bolts at 33 ft/lbs on one pass, the force to get the first few bolts to 33 was relaxed as the other bolts took their share of the load... I did three passes, in sequence to finally get all the bolts to share the same load at 33 ft/lbs...
What I really need is one of those doohickey things hanging from my ceiling that tightens all to the right torque all at the same time!! Anyone have one I can use?! Talk about time savings!!
Again, not a debate, just me sharing how I'm having fun!!
Thanks for sharing!!
