M62 Engine

Hi.
I'm looking for some info on the M62 engine.
My 840CI, 4.4,1998 M62 engine started running very roughly. Sounded as if it was not firing on all 8 cylinders.
I thought it might be a spark plug, so I took them out and they were very sooty and , I thought, oily.
Also I thought the centre electrodes had been burned away but then I realised that was the design of the plugs, namely, BKR6EQUP. I had never seen plugs like that before, being used to a protruding centre electrode. These plugs were not listed in my handbook, so I replaced them with the recommended BKR6EK.

The rough running was still there so I searched the forum and discovered that a faulty camshaft sensor can result in all cylinders being fuelled together on every stroke and cause the symptoms of a plug/coil failure. I have a new sensor on order from http://www.c3bmw.co.uk at (for Ireland) a reasonable price of £58.75 sterling. In the meantime I have taken the plugs out again and cleaned them.

I have no manual on the car or the engine and wonder would any 5 or 7 series manual cover that engine.

And finally the question: What is the recommended Torque for the spark plugs?

Hi 8Tech.

Thanks for the reply.
The sensor arrived this morning but they sent me the wrong one.
So I will have time to check out those other areas you mentioned.
I was not aware of that TIS that changed the recommended plugs.
This engine has only 75000 miles on it but it was idle for a long time,
so I have cleaned all the contacts I can find and will investigate the other
sensors.
C3 appologise and are sending me the correct sensor by express.
We shall see.
