Camshaft sensor usually gives you issues, but it will still start. Crankshaft sensor usually makes it not start.

Also about code readers, they are not always able to tell those two appart, because they run on the same circuit or something like that.

Yeah it's not super important how the rockers look as long as they are done properly, the most important part is the jacking points so you dont end up having a jack or jackstand go through the rocker, pushing the whole jacking point in.

My old E39 had that on both rear jacking points.

like I said, I have the previous mentioned symptoms. I have no idea myself anymore, only thing I can do is lift out the oil cap and see if my revs change. I got software from a E39 forum user, need to order cables and read it out. I don't want to spend the money replacing both parts even though they aren't /that/ expensive, but my job screwed me a little over money-wise. Looking for a new one asap.

Oh btw, my E39 used to have starting issues, as in long cranking if it had stayed off for more than one day, and starting issues when warm and "laggy" acceleration up untill 3000. I replaced 3 coils (since I didnt check the codes I took a chance and replaced 3 randomly) and the issues went away. Although I should mention that I replaced fuel filter and crankshaft sensor a little earlier, was going to replace the camshaft too but never got around to doing it.

But like I said, oil in spark plug holes is often caused by leaking valve cover gasket. I believe that CAN cause some running issues as well. If not, its still a very common M5x thing.

Hm, my Fiesta have bit slow starting and loss power at high speed. I discover there service way over-due because the spark plug look like worn out which mean it won't burn fuel and air very well and it possible threw cat faulty code from O2 sensor. I replace air filter, oil filter, pollen filter, changed oil and replace all 4 spark plugs, then she started up quicker and bought all power back. Could be worth check service due date?! Oil on your spark plug may need compression test, it could be failure piston, gasket, or worn valve guild.

Oil spark plug = Harder to ignition air and fuel mixture = Weaker starting.

(Underline is possible faulty that have oily on spark plug)

I serviced the whole car already, the picture of the spark plugs is when I pulled them out. Only thing to do now is an oil change. Battery is fully charged (3x charged to full by a shop). Air filter is changed, interior filter is changed, fuel filter will be changed soon. It runs fine in idle and revs fine (power only really comes 3.000 rpm + ). It is definitively one of the two things I mentioned. It doesn't matter if warm or cold, it always starts after 4 cranks. I'll wait on the software just to be sure and then fix it.

Side note, door step trims and orange front blinker sockets arrived today, sick

What about I said before about compression test?

That might be a thing^.My car sat years in the parking lot and after I did a half rebuild changing the oil retainer rings it pulled differently above 3.5k rpm.I had bad compression on piston 2 and thats perhaps because of the old rubber that went to plastic quality over the years of not being used
