Re-plumbed the CDR into my custom intake; the CDR sticks right into the rubber seal in the valve cover now, and a pipe runs from the output. Hoping to get more drain-back this way.

Added some little plastic clips to the inside of the door to stop rattlin'

Added a quart of trans fluid, I still have a leak somewhere.

Bought a throttle return spring 'cause the pusher spring plasticrap died and my puller spring is garbage

Diesels run "lean," or with a high air:fuel ratio, all the time. It's when they're running "rich" that you have problems like melted pistons & valves if you don't let off the accelerator or downshift to get some airflow.

well it seemed to fix it self it is running really good now it feel like it didn't have the power to get up and go so i was wondering if i through some more fuel in it it might run better but she is running really good today so im not sure what the problem is but i know my temp gauge is acting up and my oil pressure gauge is not working i have been looking at oil pressure gauges but i need to know dose it come with all the fittings to tie into the orignal sending unit i have noticed that the wire going to the orinal sending unit is loose on the connection so im thinking if i clam the connector a little it might get a proper reading of the sending unit any idea how to fix this promblem

A bad batch of fuel will make my IDI run different. Yeah if you get the right gauge it will come with all the fittings/wiring or lines to make it work.

Just go to NAPA, Autozone, etc, and get a gauge kit with a 0-80psi or 0-100psi gauge, mounting bracket, sender & adapter bushings, and wiring.

I still need to do something else about the CDR, it doesn't stay well. Cutting down my hose might work.

I'd rather do an oil sep. Do powerstrokes have CDR?
