Since I now have an error code stating cylinder 7 misfire, I am looking into coil packs. I hope I don't need one since they have been done. Anyway eEuroparts sell theirs at dealer price. Also, they come with a lifetime warranty. So if thats so, coil packs are no longer an issue. I would love to hear your views.
Well I demystified changing the coil pack. first of all I didn't need one. It took me 45 min to pull it out. That is because I didn't know what I was doing. I think it will take about 20 min on the next one. Anyway, here goes the problem with cylinder 7.. DON'T SCREAM!
The plugs on the third pic are from cylinder 7 the other two are from 8. I plan to change them all
Those plugs don’t look that terrible to me, if anything they kinda remind me of an engine that’s running rich
another thing I noticed is the threads are unusually oily looking on yours, do you have leaking valve covers or something? This will cause all kinds of issues from weird heat build ups, to fouling plugs etc.
No oil leaks. I had a ABC reservoir leaking recently....
Anyway, update time... (Drum Roll) I changed all the plugs; at least the drivers side. Getting the last three was challenging. It took me about two hours. I am no mechanic. When I was done and started it up, Same S-hit. Then I noticed on my cheap as hell scanner that is was the whole side. I didn't scroll down. (Yes dummy of the year) I am no mechanic, just a business man trying to help himself. So tomorrow I plan to rent a Voltage transformer from the folks in Cali.

I took off my ignition control pack and look what I saw. This made everything so much easier for me. I will not buy a rebuilt coil pack. I prefer to go the FCP Euro way to get a brand new one with lifetime warranty. I think rebuilt ones where put on this car in the past.
Fcp with lifetime warranty would be great for coil packs 👍
eEuroparts you mean. Anyway what I am not going to do is use V12coilpacts... He now sources his materials from China. Alibaba has them for $700 with a 6 month warranty. I wouldn't touch them with a ten foot pole.

i thought you’d said FCP.
I also didnt really notice anything drastically wrong with that coil pack but I didn’t want to assume

I think you may be right about the valve cover leak. I think I may try to change it when I put in the new coil pack. I hope its not too challenging. My only concern is in the rear where the turbo inter-coolers are. Let me know if you have attempted it before.
Ok, my new coil pack came in. On Sunday I will remove the old one and and take a closer look at the valve cover. With the coil pack still installed, I cannot see any signs of oil running down the side. Maybe when I remove the coil pack, I may seem something different.
Ok, the TTV12 is up and running again. Now, when I removed the old coils and inspected them, they seemed to have a tan colored substance in the coil pack tubes. I believe the fellow who put the the coil pack used a mountain of Dielectric silicone grease. This stuff was every where in excess quantity.
So new plus; installed the new pack and off to the races. Now i may have an oil leak from one of the turbo lines but very minute. I will double check that this week.
Well when I changed the plugs, some noticed a little oil and we thought maybe valve cover gasket... smh, it was actually one of my ABC lines with a small hole which blew out Friday night. I felt like putting three bullets in this thing...

I took my car in to my mechanic. I had to do that because the leak was hidden on the bottom by a cross member. the leak sprayed from underneath a pulls; it was spraying. Anyway, it turns out to be a power steering hose.

i haven’t worked on turbo/v12 mercedes, but yes those threads on the spark plugs look a little more “dirty” than I’m used to
edit- just read you’re last post that you were able to rectify the oil contamination
The power steering hose cost me almost $1300 to replace. It was a big job.
yea I’ve spent a few hours at a time under the car just replacing that hose. There’s actually a check valve in those high pressure hose(unless mine was just completely clogged) which can also fail

After I jacked up the car and look at the work which it would have taken to replace it, I buttoned it back up and sent it to the mechanic. The system was way too complicated. Also, there was too much possibilities to make mistakes.
