Dummy Plugs and Stand Pipe Torques

[LTRMC02]

I have gotten different feed back on the torque specs for the new style dummy plugs and stand pipes ranging between 33ft\lbs to 60ft\lbs. I don't have a factory manual and of course the Haynes manual doesn't tell.

60ft/lbs (82Nm) is the value you are looking for....

Thanks Bondsman, nice looking rig you have there. What coolant are you using, I hear Catipillar and Zerex or something like that are the two recommended coolants for these trucks.

[bondsman]

thanks.. Im running CAT EC-1 with a coolant filter.

valvoline zerex g05 is the same thing as motocraft gold- look for a OAT coolant no silicate

Xerex does make an elc as well... I couldn't find it anywhere. Found my ELC at a CarterCat place..

Superjet, I see you have the 6.4 banjos, I hadn't read up on this yet but have heard soemthing about hogged out or using 6.4 banjos, I'm assuming these are the fuel feed fittings going into the heads. I see that mine have check valves and looks like they can be removed. What's the deal with changing these? New style bigger or not have the check valves?

Actaully they are a bit bigger holes and no check valve. Some folks have drilled out their stock banjo bolts and they ended up weakening to the point of breaking off.

Is there much advantage with the new fittings if I'm not changing injectors or turbo right now? I'll be running an SCT tunner, still not sure on which tunes to get but going to start with some from MKM customs as they will give me a few tunes for buying all the parts from them.

Is the main purpose more fuel flow or a steadier fuel pressure to the injectors?

Also interested in the CCV mod and Zoodad I think it's called then I will probably leave it alone for awhile LOL. I guess there is always something more that you'd like to do to these trucks.

The bolts go into the block. The claim is the stock ones with valve can starve the rear injectors of fuel under heavy loads ie. Full boost heavy load up long hill. So for free pull out valves or few bucks buy 6.4 bolts. Injectors are bigs bucks
