Can we get this sticky?

Great Thread!!!

I see the pitch of head studs for a 12v are 12mm 1.5 pitch anyone know what the quantity and lengths of the Head Studs are (not bolts)???? and Also thread and lengths for the Common rail are, I'm thinking about making my own studs!

I don't think they make all-thread in >180Kpsi tensile.

Well i would not machine all thread! I would turn blanks, and have them thread rolled and heat treated!!! Smart A

Anyone have the oil cooler thread sizes off hand?

great idea:snoop:

Bump

I r gud at stuffs.

Awesome thread i had some stuff written down somewhere, no idea where it got to though.

Oil cooler pressure fittings (to the turbos)

1/8 NPT and M12x11.5 straight metric oring.

Ill try to remember what the thread size was for the electronic wastegate on the 04.5+ HE351s. That way people dont have to pay 60 bucks to cap the hole!

Anyone know the cylinder head fuel return size on a 24 valve? The one on the back of the head.

Looking for automatic bell housing to adapter length and pitch

Anyone know thread of fitting going into rail on cr? Looking to add ii dual line kit and keep all the stock stuff by adding a t

M14x1.5 same as the inlet.

Its not the same as this?

Injector return (24v)

M12 x 1.5

Its a M12x1.5

Anyone know the thread pitch on the 12 coolant temp sensor.

The temp sensor in the back corner of the 12v head is 3/4" NPT. There is usually a couple 1/2" NPT ports under the intake plenum, too.

The inlet of the piston lift pumps I have dealt with is 1/4" NPT, some are bigger but can't remember for sure if it's 3/8" or 1/2".

1/4" NPT is dangerously close to 14mm x 1.5.

Anyone know what the thread pitch on banjo bolt for a 12v injector return line is? Buddy put a fass on his 12v and removed the stock filter etc. We need to make a t-fitting where the injector return can thread in the top and the injection pump can then tie back into it and then back to the tank.

Size and pitch for ve inlet fitting , along with the factory fuel filter inlet and out lets. VE motor as well. Want to ditch the hard lines for AN fittings and a reg.
