Low oil pressure cat engine 3406b

Whats the serial number first #,s 3 is all.

 

If you dont know the serial # and arrangement # how will anyone know how to help you? Its on the cold side of the block, on the head, near the firewall. A brass tag permanently affixed, write it down and save it.

 

The serial # prefix would help, but I have a few other questions to. Does it have Jakes? Did you just decide it needed overhauled and oil pump or did a reputeable mechanic? Have you checked the oilpressure relief valve? Also a B is not a overhead cam eng has anyone checked cam bearings did they plastigage the rods and mains to measure for proper clearence which should be done anytime you are in a engine with oil pressure concerns. A 96 should have an E model I think which is overhead cam could be a whole other set of issues so really need serial # to be sure what we are dealing with

 

Look on your truck registration look for VIN # or look @ vin # outside the door next to the company name Dot # Etc. and if you need the Engine serial # you have to open the Hood and look on the side of the engine block (Driver side ) above your fuel pump or air compressor for most trucks
Happy 4th

 

Its on the block

 

It most likely a 5EK 1993 through 1997 the longest production serial # of the E's

 

Check gauge ?
