If you are asking about the cam shaft bearing caps, the answer is a most definite YES! I can't remember the exact measurement but believe it should be 12nm.. When bolting down the shafts, hand tighten each cap, pulling the shafts down evenly and then when all caps are fully closed use a torque wrench to complete the job. Regards John

Hi dear40,

The m43 engine should be similar to both the m42 and m44. The cylinder head torque settings are 22ft/lb and 90degree torque angle, and another 90 degree torque angle. Make sure to wait approximately 10minutes before performing the 2nd torque angle.

if the treads are m8 then 22 nm,m7 15 nm,

both these items do not have torque settings,but if you use a 6"long wrench(spanner)to firm hand tight. that is sufficient.dont forget to use a non setting gasket sealant,

The torque settings is more know as torque spec's, and it just means an exact measurement of how tight a paticular part is tightend. With a new engine, many differnt parts have differnt specs, but hands down the single most important thing would be the cylinder head to engine block torque. This is often done in a 3 step process, using a torque wrench, and a torque angle gauge. Are you planing on installing an engine yourself? I can get specs for you.

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.
