Shortdawg67 Posted October 24, 2023 Share Posted October 24, 2023 Engine Mack 2007 ASET-C 380/410 Combustion air temperature 2-8 flash code combustion air humidity 2-9 flash code Those are the new codes I’ve been getting; hearing this scream as I’m accelerating louder than the turbo. I need help troubleshooting. Also, How do the Turbo blades look to you guys??

Joey Mack Posted October 24, 2023 Share Posted October 24, 2023 I see a little oil and chipped teeth on the compressor area. Pressure test the C.A.C. they tend to leak at the top right corner..

JoeH Posted October 24, 2023 Share Posted October 24, 2023 What's with all that pitting around the machined part of the cast iron? Combined with the chipped teeth I'd wonder if something small went through there... 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73456-aset-c-turbo-issue/#findComment-540904 Share on other sites More sharing options...

Something has gone thru there and the snail is heating as Joey mentioned check the after cooler and the charge air system for leaks! Its starving for air ! how does the inlet wheel look? The chips that came off that wheel are melted to the housing! The hot side housing being blue is not a good sign!

Shortdawg67 Posted October 24, 2023 Author Share Posted October 24, 2023 @Joey Mack yes there is a little oil in there as well as In that gasket tube that connects to the turbo has some leak in that tube I noticed. I’m sorry what does C.A.C. Mean?? If it is leaking what would be the next step? I’m wondering if something fell in or around the air filter and the turbo blades are up whatever it could have been.

The concern is the blades are they chipped!? The charge air is the cooler in front of the rad check it for cracks along the weld at the rh top corner where it comes off the turbo! they some time s split there check all the hoses for splits and broken clamps! make sure the elbow at the top of the inlet manifold is tight and hasn't come loose! look for indications of soot anywhere on the inlet side! something when thru that exhaust side !did it also go thru the inlet or did it come from the engine it self? that is the question!

Joey Mack Posted October 24, 2023 Share Posted October 24, 2023 As you check for leaks in the intake system, take a close look at the intake manifold. Those 1 piece manifolds tend to leak. I find most leaks at #5+#6.. you will need an inspection mirror or flexible bore scope to get a good look, well, at least my fatass does... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73456-aset-c-turbo-issue/#findComment-540913 Share on other sites More sharing options...

fjh Posted October 24, 2023 Share Posted October 24, 2023 We made a special cap off tool for the turbo to pressure up the whole intake system it’s time consuming however worthwhile if your chasing intake and exhaust leaks! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73456-aset-c-turbo-issue/#findComment-540921 Share on other sites More sharing options...
Shortdawg67 Posted October 25, 2023 Author Share Posted October 25, 2023 (edited) I have found a fairly used whole Turbo for my ASET-C. When I replace my current turbo; should I replace the oil feed lines as well? Could the oil feed lines be clogged up with carbon and/or soot that could have caused my turbo to also fry up?? (Keep in mind I STILL have low Oil Pressure to the Engine!!) Or can I keep the oil feed lines and clean them out? Also, when I replace the current turbo does the new ‘fairly used’ turbo need to be recalibrated to the ASET-C?? I am also keeping in mind to inspect the charge air cooler and clean out any metals or clutterness. Anything else I should look out for?

Mackpro Posted October 26, 2023 Share Posted October 26, 2023 There are 3 different part numbers for ASET AC turbos depending on HP level. The newest turbos are the “D” series. Make sure the part number starts with a 631GC5176. Then the next number can be a EM or a DM then the last number relates to HP level. And the X on the end means reman Quote Link to comment https://www.bigmacktrucks.com/topic/73456-aset-c-turbo-issue/#findComment-541021 Share on other sites More sharing options...
