sorry if it's been covered
cliff notes:
1. I'm on my 15th BMW and this is my LAST V8 (buying their straight 6's from here on out)
2. Factory engineering and design flaw causes valve guide seals to leak
3. Often (on many V8 engines beginning with the M60 and continuing) by 50k miles oil consumption is 1qt per 1k miles.
4. Significant smoke puff occurs on startup or after idling when warm
5. Regardless of who does it (or if they have the helpful guide tool kit), valve guide seal replacement is expensive.
Decision:
a. sell the car asap "as is" with 80k?
b. sink thousands into repair
c. keep searching for "Plan C"
The FIX:
Change to TOTAL Quartz Racing 10w-50 oil
Result: ***YOURS MAY VARY****
1. No smoke
2. Oil consumption less than 1/2qt per 1k miles
Didn't really want to sell it.
