mechohaulic Posted September 10, 2022 Share Posted September 10, 2022 broken /weak spring in oil pad high pressure over ride, engine won't know it gauge and electronics will 2 Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 10, 2022 Author Share Posted September 10, 2022 (edited) This is what I put into the ASET C engine. All Pai parts which I beleive is aftermarket. Oh, and I also completely forgot to mention. I have 6 BRAND NEW INJECTORS that I picked up from the Mack Dealer; installed with this Overhaul as well! I lve spent a very damn good amount of money now and I’m over it, it doesn’t make any sense. Mechohaulic Thankyou for your input as well. Where is the location of the oil pad to this broken/weak spring that you have mentioned? Under the oil pan?

Joey Mack Posted September 10, 2022 Share Posted September 10, 2022 Wow!! a Mack dealer using PAI parts.. My local dealer is too proud to use them.. They will only use Mack parts, which means they do very little E-7/E-Tech repairs.. and $3657.00 for the in frame kit is a good price, thats around what I paid for the ASET-C I built in July.. Good luck... jojo Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted September 10, 2022 Share Posted September 10, 2022 (edited) Is there excess blow-by coming out from the blow-by tube? V Edited September 10, 2022 by Vmac3 Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted September 10, 2022 Share Posted September 10, 2022 Also lets check the turbo shaft for excess play. These problems that you have sound unrelated. Also, remove the egr outlet pipe at the cooler. Check to see if there is any oil residue on the outlet side. V Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 12, 2022 Author Share Posted September 12, 2022 @Joey Mack for this ASET C where is the pressure relief valve located?? Can a picture be provided of location if possible?? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 12, 2022 Share Posted September 12, 2022 The oil pump has one, and inside the oil filter mounting should be another one.. if the filter mount was removed, was the correct gasket put back in?? Very important... I can't post pics right now.. jojo Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 13, 2022 Author Share Posted September 13, 2022 Is this where I need to be looking at? Inside that black oil filter?? Am I looking for a loose/ broke spring in there??? Also, do you guys see on the right side of the picture that dirty light blueish thing pointing upright what is that? Is there something that needs to be connected to that???

Onyx610 Posted September 13, 2022 Share Posted September 13, 2022 No that’s not it, green part with the white filters is what your looking for. As for the “thing” that’s oil pressure sensor or temp. Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 13, 2022 Author Share Posted September 13, 2022 Ok so the green part with the white filters would be the pressure relief valve?? Am I looking for the loose/broke spring in there? Do I replace the spring or replace that whole part?? That oil pressure sensor I’m gonna say is attached but not wired/connected to anything… Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 13, 2022 Share Posted September 13, 2022 you say the oil pressure sensor may not be wired right.. thats an issue... You can put a gauge in the port that is above the oil filter, and compare the readings.. you may have good pressure, just a bad sensor/wires.. jojo 2 Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted September 13, 2022 Share Posted September 13, 2022 That blue "thing" looks an awful like a pressure switch for an A/C system. That does not look like a pressure or temp sensor. V Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted September 13, 2022 Share Posted September 13, 2022 I think vmac is right. Either way, it is not correct.. jojo Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 16, 2022 Author Share Posted September 16, 2022 Ok fellas. Go back to the picture with the oil filter housing for me. That green painted part. What is that called? I installed a new oil pressure sensor and that didn’t change anything. So if I change that green painted part I am really hoping that solves my low oil pressure issue for damn sure. Again, what is that part called? (Thankyou Dawgs!) Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 16, 2022 Share Posted September 16, 2022 That's the oil filter pad/mount... It ain't no easy change...you have to drain the coolant and remove the egr cooler with it. I think you are going too far. Have you put a gauge on the oil filter pad to compare it to what the trucks ECM is reading? 1 Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 17, 2022 Author Share Posted September 17, 2022 I have not put a manual gauge to it yet but will when I bring it back in the shop. When we’ve talked about pressure relief valve for my low pressure engine oil is this what I should be looking at and for?? Quote Link to comment Share on other sites More sharing options...
Popular Post Joey Mack Posted September 17, 2022 Popular Post Share Posted September 17, 2022 i dont think so... that for turbo boost.. until you see 'true' oil pressure with a gauge, you may just be wasting time and money on parts that wont fix it.. keep it simple.... Of course if you are filthy rich,, keep tossing parts at it and let us know how it goes.. Too many guys skip the simple diagnostic procedures because, the see all these guys using laptops and programming, and it must be an ECM or something big,,, Thousands get spent, still not fixed, and a loose terminal was the cause or the wrong sensor part number was picked and installed... Im not being a Dick, just see where this is going.... jojo 3 Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted September 19, 2022 Author Share Posted September 19, 2022 as far as I know is I’ve had my oil pump replaced from the first shop I went with that is well known in my region quite some time ago.. I am not sure if they used aftermarket or Mack brand but hypothetically if they used Aftermarket; have any of our guys heard of this issue with the aftermarket oil pump having a problem with the spring???

Shortdawg67 Posted November 3, 2022 Author Share Posted November 3, 2022 UPDATE: I’ve replaced the Relief Valve myself in the Oil Filter Housing. It did not make a difference in the Oil PSI 🥲 my next look will be to check for the Rockershafts Plugs 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 4, 2022 Share Posted November 4, 2022 I don't remember if you had put a gauge on the oil gallery to compare it to the EECU reading..? Jojo Quote Link to comment Share on other sites More sharing options...
Shortdawg67 Posted November 4, 2022 Author Share Posted November 4, 2022 I did put a manual gauge to the oil port to read it with the oil pressure gauge in the truck 😏 so I should read it from the EECU? What’s that mean if I can ask, lol 😅 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 4, 2022 Share Posted November 4, 2022 What I mean is that, the truck pressure sensor goes through the EECM.. but a hand held gauge is actual.. if the hand held gauge is reading a different pressure, hopefully higher, then there may be an issue with the trucks sensor.
