[@1962moon1]

Thank you we spent 10s of thousands of dollars from washington to phoenix new turbo and actuator new egr and cooler 6 new fuel injectors 2 DPF filters and catalyst doser valve all at Cummins / freightliner / Peterbilt and 3 tow bills Sitting in Ely Nevada last night dreading calling for a tow to vegas and saw this video. pulled out the intake manifold pressure temp sensor and it was completely encased in soot cleaned it with WD40 put it back in and truck instantly ran fantastic Like new thank you so much for posting this

[@truckerstyleshawn]

No problem! Glad I could help

[@rrmobilemaintenancellc7272]

I service part of Northern/Central Nevada and Ely, NV is one of the worst places to go down in. No repair shops anywhere near by.

[@bgesjackson2011]

I pure pulled over to the side of the road to do this... 2005 international 9400i Cummins ISX.. DAMNNN WHAT DIFFERENCE!! I done the biometric sensor and the EGR both... HUGEEEE DIFFERENCE IN POWER AND SMOOTHNESS... thanks a lot man!

[@truckerstyleshawn]

No problem brother!!!!

[@truckerstyleshawn]

Thank you yrt! If i can help i try to and answer all the coments, and if i can make a video to answer one of those coments i will

[@TravelingTech]

Great idea! I've got a cm870 in my shoo right now and going through troubleshooting low power and smoking between gears. I'm definitely gonna check that out! Thanks!

[@truckerstyleshawn]

Also check the fuel timing actuators. If they are low in voltage it will have that issue as well

[@TravelingTech]

@@truckerstyleshawn thanks for the tip. I'll check that out too.

Thank you for your videos very informative.Ive been having problems with my cummins, changed filtets, turbo,.actuator, ans is still lossing power after 90 miles.turn off cool down and run again. Code reads low.fuel.pressure. Now white smoke started this morning. Any suggestions?

I got the same engine as you have thanks for this video this is going to help I have been having trouble I don't know if we can cross and you can have a look on the engine it will help me a lot to safe money

Prior to cleaning the barometric sensor was it idling rough and sputtering while cruising at highway speeds?

[@truckerstyleshawn]

Yes

[@chadholland6847]

Hey what's going my CM870 brother, just wanted to touch base with you... I finally got my truck out the shop yesterday 2 injectiors #4 and #6 1 timing actuator Replace 2 plugs for the timing actuators Adjusted the valves

Good info man thanks

Question , Dumping fuel where ? In the crank case ?

[@chadholland6847]

Hey Shawn, what was the name of that turbo you said can for our cm870, cause mine blew last night

[@truckerstyleshawn]

Bully dog. And mine is blown as well. I have been researching on doing a BorgWarner s400 turbo conversion. Basically a pdi build on a budget. With a t6 adapter to stock exhaust manifold

[@chadholland6847]

@@truckerstyleshawn oh ok, man I tell you it's always something right; I found a couple of the original turbo's on eBay running from $600 to $800

[@truckerstyleshawn]

Chad Holland yes if you can get one with a 1.32 t6 exhaust housing

[@truckerstyleshawn]

Chad Holland you also will have to get your Ecu retuned for not haveing a can’t turbo. I am leaning tords a hoset s400 or s475 like the detroit series 60.

[@tylertucker4478]

Are these cm870 cummins any good? And how many miles can you get before it needs a rebuild. Im looking at a 379 with a 400hp cm870 in it with 900k but idk if it has a rebuild in it or not. Im a cat guy and still leanring about these isx. Any reply would be appreciated

[@truckerstyleshawn]

I like them. It all depends on how it was maintained. I have seen some that need a rebuild at 500k and there are some like mine I have 1.6m and still haven’t been opened.

[@boss7308]

I have tje same engine last week started smoking like crazy out of blow by tube! No loss of oil, oil pressure good runs the same except crazy smoke! Any ideas?

[@truckerstyleshawn]

Watch some of my other isx videos and try them out. But a lot of blow by is normally high crank case pressure or worn rings. You can try a good deturgented oil and try and clean out some out deposit in the system but that’s normally best case scenario

[@RealMC77]

Hey Shawn, Hope all is well. Does the CM870 has an CrankCase Filter? I know the CM871 does.

[@truckerstyleshawn]

No it does not

[@chadholland6847]

What's going on Shawn, well just got info from the shop yesterday that it was 2 bad injectiors, but what I will do once I get it back home I'ma clean that sensor you're talking about too

[@truckerstyleshawn]

Sounds good. And i would ask them if they know anyone around that rebuilds injectors and keep them as extras

[@joevega5477]

Hey budd thank you for your videos.you saved me $ on egr valve magic plug.🙏 thanks

[@truckerstyleshawn]

Any time man

[@rakimmason8]

I get white smoke randomly only when driving only. Most likely to happen when pulling hills or hard acceleration when under a heavy load. Engine sounds fine, weak acceleration power. Been going on for over a year now, still haven’t figured out the problem 😢 *2010 Pete 387 ISX07* *No engine light*

[@preludedudesi5208]

Working on a CM870 now, has a bad miss, #6 cylinder performance test fails, injector cut out test no change, swapped injector with test injector same thing. Also has a thump coming out the intake. Any ideas

[@truckerstyleshawn]

Did you check your valves and piston with a horoscope? Sounds like a pretty bad issue. Also check your wiring and everything is getting the proper voltage

[@preludedudesi5208]

@@truckerstyleshawn thanks for the reply, yeah I checked all that, monday I'm gonna check base timing make sure the cam gear didn't spin on the cam also gonna check the valve lash. If that checks out good it's either a piston, slight bent valve not letting close all the way.

[@alexulteanu3525]

Hi. I have 2007 Volvo Cummins ISX just change turbo today and it’s still smoking turbo work only on high rpm and change the turbo activator valv I think from left side of engine. What can be the problem ? Please help

[@truckerstyleshawn]

I would check the harness for your iat sensor. Also for boost leaks to start

[@truckerstyleshawn]

kzbin.info/www/bejne/d4DbipWPbM6lg6M

[@alexulteanu3525]

I know that harness is cut for sure but connected back. I can’t believe that that small think can be the problem. I will check tomorrow and I will instal the new one and I will change the manifold pressure and barometric pressure sensor to but I can’t find. I checked today didn’t see it but was dark.

[@saidabdulle7329]

hi trucker i have same problem and i did sensor but still have issues also i got turbo leaking oil any advice pleas

[@truckerstyleshawn]

Change out that turbo before you have a runaway

[@eagletran9]

Thank you sir 👍

[@truckerstyleshawn]

No problem

[@chagoquintanilla8151]

My turbo keeps cutting out at 1300 1400 RPM 35-45 MPH then kicks back in. I just replaced EGR, Speed sensor and exhaust pressure sensor no change. Any ideas?

[@truckerstyleshawn]

Is it a cm870 or 871?

[@truckerstyleshawn]

Your vnt may be bent or clogged. So I pull the cas from the turbo and check the vanes on the vnt.

also check wires to the crank case they get cut from harness yes one tiny wire will shut you down

I'll tell you what man that was a very detailed informative video that I really appreciated. I'm running the same motor. New to me . Not looking to get taken advantage of. So all the tips/tricks and info you got I'll watch!! and it's time to clean my sensors. IMAP also!

[@truckerstyleshawn]

Glad I could help man

[@bikerboy2k142]

So let me ask u what is your opinion on the isx cm870 engine as far as reliability and fuel efficiency and maintenance/Parts cost? Reason I ask is because Im looking at swapping my Volvo ved12d engine with either this isx cm870 engine or the Detroit series 60 14L engine. Main reason for the swap is more power and parts/shop availability. As well as maintenance cost and fuel economy. I figure u and any one else who has this motor or had it can better help me decide on what to do.... Thx in advance and be safe out there

[@truckerstyleshawn]

Isx is good but series 60 would be your best bet for cost per mile.

[@fvazquez201236]

Check egr tubes wrapping around the back of the engine for a silicone hose which is ignored, i had a howling sound, low boost pressure, the freaking shop changed the egr valve, because the code popped up, without checking all possible scenarios but think we have deep pockets to drop stacks. That hose will cost you 75 compared to thousands after these rat shops get their hands on it.

[@1962moon1]

I have that same howling sound will check the tubes thank you
