Dirtymilkman Posted September 8, 2022 Share Posted September 8, 2022 I would bump your idle RPM's up first. 625 is to low. 2 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 8, 2022 Share Posted September 8, 2022 650 is pretty good,, right ? Dirty milkman.... I dont like 625... I even bumped a couple E-7's too 700 just to smooth them out, and oil pressure was a few pound's better... jojo 1 Quote Link to comment Share on other sites More sharing options...

First make sure the parking brakes are applied and the engine is idling at temperature. Cycle the cruise control On/Off switch 3 times, the engine rpm should go down to 550 rpm. With the Set/Resume switch (its a spring loaded switch), toggle the resume to increase the engine rpm. Once you have set it to the engine rpm you want, press the clutch in. It should stay at your desired rpm. If its an automated transmission, then you would need Tech Tool to set the rpm. Hope this helps.

Most of these were set to 650rpm from factory. 1 Quote Link to comment Share on other sites More sharing options...

Dirtymilkman Posted September 11, 2022 Share Posted September 11, 2022 50 rpms will bump your oil pressure to almost 30 I bet 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 11, 2022 Share Posted September 11, 2022 Hell, going from 625 - 650 will bump it up.. just sayin'... jojo Quote Link to comment Share on other sites More sharing options...

Not metal to metal but for sure a squeal that I can’t figure out where it’s coming from, for sure passenger side Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 13, 2022 Share Posted September 13, 2022 Did you check the turbo for movement of the turbine? Also, look at top right corner of the CAC..front side. See if there is oil or residue at the weld where the viens attach to the side tanks.. a pressure tester is a key tool for this.. a few guys here made thier own.. jojo 1 Quote Link to comment Share on other sites More sharing options...

Run the engine and spray soapy water at all connections. Quick and easy since you don’t have a pressure tester tool or one made up yet.

Onyx610 Posted September 13, 2022 Share Posted September 13, 2022 (edited) And yes check the shaft for play. The turbine could be scraping the housing. It will expand at high speed. Edited September 13, 2022 by Onyx610 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 13, 2022 Share Posted September 13, 2022 does the squeal ring out as a steady squeal, or is it more of a ,,, Chirp,, chirp,,, chirp? and speed up with RPM's? if you dont have a stethoscope, you can use a 2 foot longish peice of 3/8" hyd. brake tubing, to listen to the engine and its parts, ie: alt./ air comp. I have couple thoughts, but will wait for you to reply with new info... Jojo Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted September 16, 2022 Share Posted September 16, 2022 Is it draining from the drain tray onto the ground? Or onto the floor? How about a pressure test of a full system and look for engine leaks. Park on a clean spot or through a sheet of cardboard under it if you need too.. Hell, there should be obvious signs of a leak, at that rate.disregard the heater core idea for now.. 1 Quote Link to comment Share on other sites More sharing options...
