Bmw E30, 316, 55 kw, 1987, M10 with carburater

Hey Chuck, run a bottle of fuel injector cleaner in a full tank of gas and see if that takes care of the problem.

what engine, what country. what year, (3 strikes, and out)
we cant guess. 2001 to 2014.
4.7 L 240 hp (179 kW) V8 (2001-04)
4.7 L 282 hp (210 kW) V8 with VVT-i (2005)
4.7 L 273 hp (204 kW) V8 with VVT-i (2006-07)
no spark at all cylinders, check them all.
if all are dead, the $9 scan tool tells me why, with DTC Pxxxx
ever done a tune up ever? if not , why not now.
tune ups, correct bad spark and bad filters.

no spark winter, that is because, its cold and damp
and spark parts just hate damp when parts are old, 1920 to now.
If it runs now.
is the CEL glowing at any time running.
yes, why not scan it, got P0300s or P0301 to 8?
bingo

Go to auto zone they check for free, then will know what's is next.

check your carburater.

Don't shut it off.

It's the automatic choke!

The choke is "closed" or barely open... When cold, the engine needs a RICH mixture (more gasoline, less air). When the engine warms up, it requires a LEAN mixture (less gas, more air).

It is probably creating BLACK tailpipe smoke ... that means unburnt gasoline. (Blue smoke is OIL, white smoke is WATER).

Put the parking / emergency brake ON.
1. Remove air cleaner assembly from intake, use a carb cleaner spray or throttle body spray cleaner and spray just a little. (AutoZone $5)
2. Find the accelerator arm under the hood.
3. start car, rev the engine to make sure how to operate the accelerator from under the hood.
4. Carefully spray into carb / throttle body and work the accelerator ... don't let the engine die...
5. Watch out for "backfire"... it may create a small flame out of the carb. It will extinguish itself in one second.

6. You may need to do this two, three times.
7. Add a "complete fuel system cleaner" to your next tank of gas ($8).

That's it! ... pretty cheap, too.

Hope this helps!

Check the Air Mass sensor and Oxygen sensors.

If gais getting in the oil there is only one reason, it is getting by the rings, causes are always rich cylinder conditions such as cold start mode remains on due to a defective ECT sensor, also defective fuel injector(s) will cause this issue, cold running engine from a stuck open thermostat can also be a contributing factor.

BMW cylinder torque setting all models

According to my service manual as follows.

Cyl head to engine block (torx e12 M10 bolts)

Stage 1 30nm (22 ft – lb)
Stage 2 + 90 degrees
Stage 3 + 90 degrees

Cyl head to lower timing chain cover 10nm (89in – lb)

The tightening sequence is from inside to outside crossover as normal. Loosening sequence is from outside to inside crossover. Remember to set torque wrench at low setting and work gradually up through the whole sequence until you get the desired torque.
