I've used the search settings and also googled this question. Searching this site produced nothing and Google gives more than one answer.

What is the torque wrench setting for the intake manifold nuts? I have seen numbers from 4 (!) to 10 ft lbs.

What is the torque setting for the rocker arms? Again, a couple different numbers but 14 ft lbs seems the middle.

Any advice here?

Thanks

Rob

Because I hear this Q pretty often I posted a table with the most common torque values on my site in the file/downloads section (bottom of main page) HERE

The Haynes manual has a lot of torque values at the beginning of each section. For 8.8 grade M8, the standard torque is 17 ft-lbs.

I would think the intake manifold nuts were in that range, but Haynes calls out for 4.35 ft lbs. I've never seen that low of a setting on such a big bolt and can't figure out the logic behind it.

Is it a typo? Can someone explain why it would be so low?

Possibly because of the phenolic spacer between the head and the manifold? I can't remember what I torqued my carb manifolds to, but both Clymer manuals I just checked had nothing for the intake. Not even under "Fuel Injection".

Value is based on the stud size. Not the nut.

I get that, but again-why 4 ft lbs on an 8MM stud?
