Installing new injectors and cleaning the EGR port

Need torque specs for reasembly
1) Upper intake to lowere intake
2) throttle body to upper intake
3) EGR valve to upper intake

Cheers

Howdy Carl,

I couldn't find my Haynes manual that lists the torque spec and I thought there was a document in the Tech Articles section (look at the menu near the top) under the engine section...but couldn't find one...

If you can find a haynes manual it will have them...or many others...but if I recall these were all tightened to inch/pounds...I know this because it meant I had to go out and buy another torque wrench because mine was in foot/pounds...but I think you can get away with tighten till tight and another 1/8" if it will go...

These are aluminum and usually can't take too much torque...

Tight with a 1/4" ratchet.. Lol thats how I do it. The only three things I torque to spec are head, Mai and rod bolts..

If you went to 10ft/lb you would be safe, IMO. I have not used a torque wrench on intakes except on 390's[cork @front & rear] and 3.0 duratec[plastic manifolds].
I have removed & replaced the throttle body a few times to R&R the cam cover gasquet and have yet to replace the TB gasket. I just push it in place, and wiggle until I can feel it fit into the 'old spot or grooves' that it came from. Seems to be working ok... The bolts have a 12-pt head I think on my 85 at least, and I just happened to have a socket of the proper size that was also a 12 pt.
In short, these torque values are flat surface to flat surface with black paper gaskets that are not deformed too much by the installation. Head gaskets, in most cases, need to seal against a lot more pressure and coolant & oil passages, and additionally, take care of the expansion of the head & block from temp. These are pretty much the same, flat, with very low pressure differential so are not as touchy.

Thanks for your advice on this. COmmon sense tells me how much I can tighten things, but I always like to check if there are torque specs and match those.

I'm with the others... "feel it out" but here are the two I found. Source: nos chiltons, from when they were still good.


1. 15-22 ft. lbs
2. 12-15 or 15 to 25 on the dual plug motor
3. Couldn't find. I'd keep it around 15
