So I've read the article about spark plug replacement, it seems easy to follow. One unclear thing is exactly when to do this, some where between 60k-100K???
Mine is 07 E63 base at 65K, is it to soon for the spark plus replacement? How do you know when your need one? Thanks
I just did mine last week at 73,000 miles. I have a feeling mine were changed before I got the car at 59,000 miles. 2 Reasons:
1- some of the bolts seemed slightly stripped on the coils.
2- aside from 1 spark plug, all of them seemed in OK condition.
Getting the coil out on the right back side by the firewall is a PITA, there's a tube that is sorta in the way.
(these aren't my plugs)
most of my plugs were a little dirty, but they all had a decent arc on the top part.
On thing to note about that 2007 maintenance manual.
It was the first year for the M156 and 722.9 transmission. Change the transmission fluid every 40K, not once at 40K.
Same with differential.
Can you share what the recommended interval for both spark plug and diff fluid change are? I followed the link you shared and all I could find was a maintenance booklet, which has no useful information. Attaching the page where 50K is mentioned.
I pulled mine for headbolt replacement and found oil deposits on all of them. I have 32600 miles on the car. High crankcase pressure and lack of a catch can seems to be the issue. I tried to rig up a aftermarket catch can but the pressures gave me leaks. Maybe one day I'll be able to afford the $600 catch can, but not this year.

Do you have any good reference for head bolt replacement how-to? I cannot find an experienced mechanic in MA who have done the job in the past. I am sure there is someone out there, but I cannot find.
I purchased the manuals, and watched Tasos's videos on youtube. I also messaged him 2 times to confirm a couple of things. I wasn't wearing my glasses and used the white line for timing the first time around, and after talking to him and watching a video again I saw the 40' mark. Cost me 2 more friction washers and a Saturday to get it right. It isn't rocket science, and I could probably do it in 6 hours if I had to do it again. If they are charging you more than 6 or 8 hours then I would find someone else. If you do it yourself and a helper you will need the cam timing tool, torque wrench to 90NM, and the parts. I will also mention the different head bolts, mine used a T50 and not a T60, and I am going to guess mine would be ok. They did have a little corrosion under the heads, but I suspect they would last. The T60 sized bolts have less material and are probably the ones failing. In the end its your rig, and you have to decide. My car has really low miles, and services done on time. If the car has had old coolant or regular water added I would replace them.

Good luck.;
In order not to hijack this conversation, do you mind if I Pm you? I watched his videos too. Can’t figure out timing tool part
