Engine TQ specs

This is a copy and paste from that other forum...

I will be updating as I get suggestions or find more!

 

Apparently this engine was not built by people with muscles. 60ft/lbs all the things.

 

except for the axle nut haha I had to barrow a TQ wrench for semi truck pinion nuts to torque my axle nuts, and no that's not a joke.

 

Any chance you have the crank girdle torque specs?

 

Updated! cant believe I missed those haha added a little bit more as well

 

Thank you, great to have all this in one spot.

 

This is a really nice resource and will come in handy

 

Looks like the torque rating was taken from the G35M-R and not the A26MX-R which is our transmission/turbo engine setup. They are just a few pages apart in the workshop manual so easy to miss. The right torque should be 151.3 - 161.1 Nm (111.6 - 118.8 ft-lbf)

 

updated, good catch and thank you much sir!

 

Awesome thanks for putting this together! Starting reassembly within an hr

 

Glad I could help, when I was building my engine I kept getting pissed when I couldn't find a spec or if I has to dig forever for one, drove me up a wall

 

Definitely! This was amazing last night, got almost every placed back on the engine! Anyway thanks again

 

So the intake manifold.... is confusing. Where are all of the bolts?

 

Not every bolt will be in every picture, everything would be insanely cluttered if they but every bolt in every picture haha just tighten them inside out

 

Thanks for this @Need2pu quality information.

 

I do what I can

 

I can't find the head gasket procedure in the workshop manuals. Do the head bolts call for any lubricant? I would think enine oil but I can't find any info anywhere.

 

Torque spec thread, not which parts to lubricate thread. Also I dunno, I'm being helpful right?

 

In my mind knowing if they need lubricated or not is a pretty important part of torqueing! -

 

Good info. In the past I had to spend most of the time researching torque specs. Then it ends up the torque specs would be hand tight, hand tight + 1 turn, tight but not too tight, normal person tight, and muscle man tight lol.
