In the Rave Manual Torque Settings section the Torque for the Exhaust Manifolds is listed as 40 ftlbs. In the Cylinder head Directions it is listed as 28 ftlbs.

This is a pretty big disparity. I have been using 28 ftlbs, and it appeared that there was a bit of a leak in a couple of places. What do you guys think about going to 40 ftlbs.?

 

I think i did 40lbs on mine

 

I'm glad you are asking these questions, as I prepare to put mine back together next week.

 

I didn't use a torque wrench on the exhaust manifold bolts.

I *did* tighten them in a pattern similar to the head bolts and made 2 passes.

You've got a lot of tolerance in those exhaust gaskets to forgive a lot of errors, for one thing, and if you have a leak there's always copper exhaust gasket sealant to slather on the outside.

Plus you can loosen and re-tighten those exhaust bolts multiple times, as desired.

 

 

Collie, if you can reach the manifolds easily after total assembly then do 30lb/ft and later when the engine has cooled down do an extra torque to 40lb/ft. Although it seems a very hefty torque on 10mm studs considering it has a laminated gasket.

 

Thanks Offroad. I will do 30 and see how it feels.

 

I'm a horrible person I just tightened them

 

$%&. Now I feel guilty. I'll go to forty too if it makes you feel better. I don't think 40 is like, excessive.

 

No I meant no torque wrench, just a 3/8 ratchet and they felt tight to me lol
