  1. Pickup tube is same on the small and big oil pan, the 51 qt is just deeper.
  2. on the vmac engine when it would quit running when it was hot and would not restart Mack said to pour a gallon of water on the governor of the fuel pump, if started it was I not sure but I think it was the magnet or sensor in the governor need to be replaced. I read your engine wont restart after cutting it off but give it a try and see.
  3. can you hear a noise thru the air cleaner, sounds like you might have a lifter head come off. Watching the valves with the motor might not show up. I would go thru the valve adjustment and see if one is loose, it will make a popping sound.
  4. Email me at g1956p@gmail.com and give me your phone # or I will give you mine
  5. I've got 2 732GB2696D new 18 stud mack heads in original Mack box NOS with 3/4 corner stud, they are naked heads, no valves.
  6. Swap #1 and #2 injectors and see if it goes to #2, If not pull delivery valve on the injection pump and swap #1 and #2 and see if it goes tp #2
  7. If I remember right there is a big 40 amp fuse along the bottom of fuse panel that is marked on the panel or wire going to it heater/ac. I dont think it would be bad or the fan would not work. Does the push button for a/c light up, Also it should work if you put the lever to defrost it should kick the a/c on. It goes from the control to the thermostat , you have to pull the front cover off and you will see if it has power to it and power leaving it, if not it is bad. On the ones I seen there is a in line fuse in the wire that goes from the thermostat that goes to low, high pressure switch, follow the wire on the thermostat wire and look for the in line fuse in the a/c heater box.
  8. Clean out the bottom of cup holder, there are 1 torque head screw in the bottom of each, remove and lift cup holder out.
  9. We had a 2005 CXN 613 with ac427 kept it till 1260000, all ways kept good oil pressure. lowest was around 45 at 1300 rpm when pull hills, I have seen where wrong gasket installed on the oil filter mounting bracket to block, you might check that.
  10. Is this engine a E-tech or a E7 older, The E7 uses the screw in sensor at the front of the flywheel housing, the E-Tech engine uses the sensor that push in from the side and a little bolt to hold it in. There is a difference in the flywheels. The E-Tech has one tooth on the flywheel that has been cut off. The older E7 has 6 holes on the front side to line up with the sensor. Make sure you got the right flywheel. Also did the crankshaft have a dowel pin in it, If not it could be installed in the wrong place.
  11. VMac 1 came out in 1990, VMac II came out sometime around 1995. Mechanical pumps were available until the VMac III ETech came along.
  12. By the picture it also shows it came out with to fitting with a small pin hole in it from factory, not the old style over flow valve in the picture the sent you. We have also seen the plastic tubing that goes to the intake mainfold have a pin hole in it, we would pressure check the tube and diagphram together. Like I said if TURBO LAG is the only problem pull the allen head plug on top of the governor and there is a cog wheel like a brake adjuster in there, I think you turn the cog wheel toward you from the side and you can get rid of the lag, we would turn the wheel a few cogs and test drive down the road and if not enough pull over and adjust more till we got what we wanted, just a small amount of smoke and quick pickup. I will say no more. Good Luck
