  1. Ve pump question

    General Discussion
    Geeez I would not be doing any more business with that pump shop if they didn’t know by looking at your inj pump that it is an older wax style KSB. Yes, it is backwards compared to the newer IC inj pump with KSB. 1st give away is the length of the delivery valve holders. The non IC pumps holders...

    Char is correct. Large turbo & large exhaust housing = slow spool

    Oh boy, that turbo exhaust housing is going to be sloooow to spool. Just saying.

    Charlie, no worries on the 91.5-93 inj nozzle size. No one person can know it all or remember it all. I stick with generally the mech inj engines because of this. After 26 years, I'm still learning stuff. I've recently dug deeper into the valve train of the Cummins engines and understanding the...

    For what your doing, the 16cm is a good compromise on spool up vs fuel mileage. I sell a fair share of 16cm housings for the 1st gen crowd. You want/need to keep boost under 10psi as much as possible to get good fuel mileage. Going over 10psi isn't going to hurt anything but fuel mileage. So the...

    I'll chime in. I have a bit of experience with what you are wanting to do. I bought a 1993 W250 with 6bt new off the showroom door and owned it for 17 years. Been messing with these engines ever since & I'm in the Cummins diesel business & have worked on hundreds of these engines over 26 years...

    Certainly isn't a P7100. Charlie is most likely right on a A-pump.

    Well that sucks. Keating is a decent company so I’m sure they will look after you one way or another.
  9. Ve pump question

    General Discussion
    I'm surprised your questioning the pump shop diagnostic explanation, when yourself even said you know case pressure effects timing. Yes, what you explained your pump was doing is correct for the pressure regulator valve failure. This is different then the pressure relief valve/ fuel return on...

    Well I'm glad it is fixed. I knew it had to be either timing or bad fuel ( which will have a delayed flame front ) as mentioned prior. Time to put some miles on it :)

    We have had great success by putting a nice steady stream of rtv sealant on the sealing side of the tappet gasket & waiting till it just skims over to the touch....then installing it. Make sure the tin covers bolt holes are not dished from over tightening ( make sure are flat ) as some people...
  13. 4BT piston lift pump spring questions

    General Discussion
    Up to 16psi max is considered safe for a stock VE pump. So anything less than this psi, is considered a low pressure pump. There is benefits to running the higher safe psi over lower psi. The higher safe psi will allow more timing advance with the higher case pressure. Along with better throttle...

    General Discussion
    The lip part of the seal is not the problem at all. It's the actual whole seal itself that pushes out with too high of psi. That's why the aftermarket kits are a bad ideal, as they push out even easier. Many loctite the seal in place or stake it and run 30+ psi with the stock bosch ve seal in a...

    Starter is on the driver side and the adaptor plate for the G56 is the same for the NV4500

    I own a 01 Golf TDI std & a 12v Cummins with a G56.....similar on the lug deal. As long as your not trying to apply too much power, the G56 is happy to cruise along at 1500-1600. But you will find the sweet spot of a Cummins is between 1700-1900 for best fuel mileage on flat ground, unloaded...

    Problem with any of the NV transmissions is finding good parts now. Since NV went under, everything i've seen or heard for parts for them has been junk. Unless something has changed recently? With that said, the NV5600 is stronger than the G56 overall, due to cast body vs alum but the parts for...

    K, your good on timing then. Putting conditioner in bad fuel is only a bandaid. Drain tank, blow out lines etc & put known good fuel in. You can't see if your pulling in air unless you put a clear line between the filter head & injection pump. I have a test section I made up many years...
