Thanks for your replies. I'm not even "sure" it's running rich, since the stainless tips went black (on the inside) just a day or 2 after the delete. Could be totally normal.
As far as AFR, maybe that's valuable to have.
10w60: I had the oil pan replaced & did provide the dealer with Castrol Edge 12w60.
QUESTION about this though, does the S62 consume oil? Should I add a quart?
Could low oil cause a tick? I've put on maybe 1200-1500mi since that pan/oil change. If there's a rule of thumb please share.
ALSO: I've noticed my oil temp needle doing a little more dancing than usual....which leads me to think that maybe there's something going on with the oil.
Location of the tick: Definitely NOT heard at the engine. I had a collapsed lifter once and I just drove around until it filled back up. No issue there. But the engine is smooth & quiet from listening under the hood. The sound seems to be "perceived" from after the engine, though obviously could originate from the engine. 82k miles
Apart from getting my AFR, what else you got in your arsenal? Something I could figure out quickly and, you know, free
Seriously? Even though the S62 has a unique procedure, I wouldn't do that with ANY car I own. That is why most cars have a dipstick (newer ones have an onboard display).
Over filling can also do damage. You should get a warning light on your display when you get between 1.5 and 2 quarts low. But don't rely on that. Being down 1 quart should not cause ticking noise at idle or light load at the engine and will not cause ticking downstream of the engine.
So, do yourself a favor, please read the procedure and measure, something you should be doing on a regular basis anyway(every 2-3 gas fill-ups in normal driving).
As to oil consumption, each motor is different. It goes into how it was built. how it was broken in, how you drive and partly which oil is used.
In general, older motors (pre March 2000 build) motors tend to use more oil. The newer motors as of 3/00 had a change in the piston ring design leading to lower oil consumption in general. My motor barely uses a quart every 7500 in normal driving, but if you are on it hard, you will consume much more oil.
