Type IV torgue values

[darkbeer]

I am fixing all the vacuum leaks that have developed over in the intake for my (new to me) 912E's L-Jetronic FI......
I don't have a 914 or Type IV manual so I'm not sure how much to torgue the manifold/head studs now that I'm putting it all back together...(new sleeves, lg & sm inj. seals, int. manf. gaskets, epoxy small crack in the plenum box, clean up the throttle body, repaint intakes, new fuel & vacuum lines,etc.etc.)

Can someone help me ??? I'm guessing 15 lb.s, but I really don't want to guess....

THANKS GREG

I checked Haynes' and Hussey's 700 Tech Tips and can't find anything for the manifold studs.
Lotsa luck...I replaced everything you replaced and still seem to have a vacuum leak.

Standard 8mm torque, 13-15#. I use 13 on questionable fasteners and 15 when I know that everything's perfect.

Here is a link to the 912E FI manual on my website, which may be of help to you:

The manifold nuts are M6, not M8. I'd go with 10 lb-ft.

You crazy long haired relay thief... you are WRONG......

The studs that hold the manifolds to the head are 8x.125. 15ft/lbs is the proper torque spec for them....

[Dave at Pelican Parts]

Oh, heck!! I was thinking of the nuts that hold the injectors in--D'OH! Yes, the manifold nuts are M8.

Say hi to Betty for me, Clay!

WE can always rely on the 914 fixit gru. Come to think of it, Clay does look like Mike Myers.
