Torque settings bmw

USA car or not. some cars made else where are not the same.
yes made in 10 plants world wide, my be not the same.
first off most cars now use TTY torque to yield on head bolts
and that means not to ReUSE them ever.
the service manual shows 2 things
the order
and the TTY methods and rules for all bolts there.
1.4L engine
sounds to me the engine froze iced up , lacking antifreeze or overheated max.
my online FSM , shows 1.6L and 2.0L only in USA>
so is that it? which one/? to post a question about any engine
tell what engine is there first. or post the VIN with xxxx at the end
the engine code is there. but not told, sorry , I'd hate to guess
or post for 3 engines is a waste of time.
if I google search 1400 I get no hits, why is that, IDK> how odd
is it a typo,(major)
there is 1.4L sold in some countries, Canada, or UK or other english speaking countries.
GM/Daewoo E-TEC (Family 1)

I give up ,my book has no 1.4L at all
so can not read the engine page to you and would if I could.
in USA to fix cars it is super wise to join and pay
for Mitchell-1, DIY manuals.
and read. and not make blunders in this area.

here they are in all their glory, in ASE school we get free access.
it is that good

There's a better chance you have the gasket on wrong although improper torque could do it as well but in either case the head will have to come off again. I hope this helps. Take care.

Over torqued and you run the risk of a stripped thread or broken head bolt. Under torqued and the compression gas will leak past the head gasket and burn it out.

With it torn down that far I would to be safe and not go through that much time again .

Hi
firstly, do you have the equipment to change the head gasket.
ie: a suitable torque wrench for the head bolts?
do you know how to re-time the engine having removed and refitted the timing belt(which you should renew)
I`mj looking at the worshop manual now and I presume you know how to strip an engine
The important part is when you replace the head (having made sure it`s not warped or cracked) and having cleaned all mating surfaces, you should have ten cylinder head bolts the tightening sequence is ____________________________
8 6 2 4 10


9 3 1 5 7
_____________________________

the torque settings are assuming you`rs is a M.40 engine is stage1 30 n/m stage 2: angle tighten 90 degrees stage 3 angle tighten 90 degrees.

Good Luck

Its usually from the center out in the next most opposite bolt (star) sequence. ie. if its a 14 bolt head 1-7 top, 8-14 both from front it would be like 4-11-3-12-5-10-6-9-2-13-6-8-1-14-7. you just want to avoid tightening a bolt outside a non torqued bolt to prevent head or gasket damage. torque specs are done in degrees, ie 44 ft/lbs, then run it 15 min then tighten another 33 degrees, then run it another 10 minutes and final torque another 25 degrees.

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.

yes time -serts can be useed to be torque

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.
