Injection pump timing has been checked and set. I am working on valve timing today. Does anyone know the answer to my question about the intake Psi sensor? Does E7 sometimes have them? I can not fined one on the engine harness or codes for one or find one with the scanner. It seems like the ECM would need that info! Thanks

yes it does have 680 Jake brake Housings

yes Cam was changed and customer has no idea what cam they used! Is the cam number on the front of the cam. Not sure about the valve lash we have not done it. Customers mechanic did it. Can it be that far out to be this low on power? It does have the electric plug I did look at the pins at the Deutsch round connector could not find anything obvious. It will not run and throws codes if I unplug it? are the pins you are talking about inside the governor housing? Should the valve adjustment be the first thing I need to check? Also saying the Cat. Way are you referring to using valve overlap on cylinders 1 or 6? Vs Macks 3 120 deg marks? Thanks for the help.

I got a basket case here and could use some help. I Have a customer that did a out of frame overhaul on a 1995 ch series E7 because a rod bearing failure taking out the crankshaft. I am not sure about the whole story this is all I have been told. However now the motor has low power since the overhaul. Truck will only go 45 mph with a trailer on flat ground. No smoke only 8lb of boost. The intake, turbo and air charge cooler have all been checked for leaks, The engine has no Active codes and goes to 100 load according to the scanner. Fuel psi is 28 psi under load, air filter and exhaust restrictions have been checked. First Question, I see no Intake Psi sensor sensor only air temp, two wire sensor is the only sensor in the intake manifold. Does E7 not have a intake psi sensor sometimes? I can not find a three wire plug anywhere on the engine harness for a intake psi sensor or a parameter for it on the scanner? I have not ruled out injection pump having issues do the metal in the oil from the rod bearing however, I would like cross off other possibilities before sending it off. The engine starts right up and idles fine just no power.
