.. oh one more thing .. a bit too big of a gap will not hurt anything .. it will be just a bit louder .. too tight is bad! because the valves may not seat properly and that can damage things ... err on the side of loose

10-4 on the rear wheel direction of travel... I just buttoned everything back up; I ran to the auto parts shop to get a 13 mm spark plug socket, but it still isn't deep enough - I may just purchase the BMW tool part number and revisit on another day.I will leave the forum open on the laptop if you get stuck somewhere ... just go about it easy and you will be done in no time ... oh and when you turn the rear wheel try not to turn it against the driving direction ... it is not super bad .. but it is easier on the timing chain tensioners that way
I wonder what the use of the Reverse Gear plays on the Timing Chain and Tensioner; if any, since the Transmission is in Neutral?I will leave the forum open on the laptop if you get stuck somewhere ... just go about it easy and you will be done in no time ... oh and when you turn the rear wheel try not to turn it against the driving direction ... it is not super bad .. but it is easier on the timing chain tensioners that way
I ordered the spark-plug socket from Max BMW; he recommended the following P/N:I didn't have one either .. I just used a regular slim 14 mm deep socket that I had in a set. Well you are doing the right thing ... don't rush it a couple miles back or forth matters not ... screwing up does!
Edit: Actually I am full of $hit ... 14mm or 9/16" !!!!
I think nothing really ... in order to use the reverse you have to have the engine in neutral and running ... the reverse is actually electric ... from what I have been told (can't verify this myself) it uses the starter motor for power. SO IMO there is no connection between the timing chain/tensioner and the reverse lever ... I think the lever just simply locks in neutral and maybe shifts in a gear that let's the starter be used a power unit. won't know for sure until I have to open one .. and I hope that will be a veeeeery long timeI wonder what the use of the Reverse Gear plays on the Timing Chain and Tensioner; if any, since the Transmission is in Neutral?
I have been told that it would be more accurate if both valves are measured at the same time to avoid play throwing off the reading ... this said it will try it next time (another 1000 miles) with 2 separate feeler gauges using one makes it a bit more difficult to see which one has which play.Is there a benefit to having the feeler gauge on both valves at the same time vs doing them individually?
And that is for people with 4 hands ... sorry I couldn't resist
Thanks for that info ... I only have a ground out SEA wrench that I use ... so I didn't know the actual size !
I originally used a 1-7/16" wrench, which I taped in order to make up the difference on the hex final drive. Got the caliper out and measured the above mentioned hex nut, and ordered a 46 mm wrench from Amazon.Thanks for that info ...
