Hi all - My Haynes manual doesn't list the torque amount for the EGR chamber cover, and searching revealed nothing more than EGR valve torque specs, which are in my Haynes.
Does anyone know the proper torque specs for the chamber bolts?
For reference, the chamber cover is part#31 in the below diagram.
That information is listed in the service manual that is available on this site. The torque specs are 7 ft-lbs.. They just need to be hand tighten down. Most torque wrenches are inaccurate at those levels and will probably "click" well past beyond the 7 ft-lbs range and will probably strip the threads.

@mykizism nailed it. it's prolly around 89in.lbs. from what i've seen, a pretty common value for non-load bearing small fasteners (like, those that fit an 8mm socket). You can find a torque wrench that can hit that spec in the 1/4" drive variety, but it's hardly worth while unless you know yourself to be heavy handed. a cheap torque wrench could go by it.. also important to note that the first 20% of values on any click-type torque wrench i've seen aren't even rated for accuracy.
so. if you have a 20-100ft.lbs wrench, the total number of values is 80. 80x0.2=16. so adding that 16 to the lowest value, 20, said wrench wouldn't be rated for accuracy until set to or above 36ft.lbs.
you can also find the manual uploaded on this forum, though I'm unsure about ease of use being comparable to buying the document and running it in adobe with all its hotlinks and ability to punch in page numbers like 9-22-03.

Hey Pyts! Thanks for the info. I bought a manual from that eBay link and it turns out I bought the very last one of the 51 units for sale haha good timing.
I've got 2 torque wrenches, a 1/2"-drive ft-lbs and a 1/4"-drive in-lbs. The 1/4" isn't a high end wrench though and it's only good for rough estimates I think.
