Don't know how many of you have these trucks CL700 with cummins isx However ! We have a fair few in my area after the death of the V8 ! the one we have in the shop now we rebuilt approx 1000 hours on the build and we are working on the second reman head that has cracked is there any one here had experiences with these and any thoughts on WHY! other than it being a cummins ! WHY Are these heads cracking the cracks are at the injector holes out and between the valves! the EGR Has been Deleted dont know if this is causing too much heat ? Should we be replacing the injectors? are we setting the injector to tight? JUST seeking input! Experiences Please!! If any! Thanx

milkman did you resolve this yet? unfortunately with out the vcads program your running half blind!

Have you owned the truck since new ? Has this problem come about or is it an inherited problem I guess Im asking!

Possibly the egr valve is stuck open or turbo stuck try giving the valve a tap

Merry xmas ! ANY Codes!?

you should not SEE Smoke Of any kind! DPF should be collecting it you may have a crack in the dpf!

depending on the year and fuel pump there were two timing pointers the rob bosch pump had a different pointer for timing and valve set pointer

AC 460 pulled b trains for ever with this till now! That's likely why!

Yup its pushing the note a tad! We just had long time customer show up yesterday with a leak behind the compressor gasket leak RIGHT ! NOT !!! Cracked a block ! Kinda sad he has spent good money this year rebuilding an engine just to have the block give out!

so if the screen issue don't conclude this saga ! Next To find leak on head gasket ! Try this. drain coolant to just below thermostat level remove water pump belt and stats fill the housing to stat level run the engine and watch for bubbles If the bubbles come from the back it can still be the compressor from the front its obvious what to do!

Now As for the coolant filter we once had one of these and it was low liner protrusion same symptoms YOU HAVE rad cracking AND WOULD BLOW THE FILTER OFF Last resort thought! throws up a red flag for me! check the screen if its not there your going on a head trip in my opinion!

Your welcome 🙏 good luck with your issue keep us posted on the progress

GREEN WTF ? Does the engine have two heads or one big head the MP engine will have MP7 or MP8 on the intake manifold RED engine THE E7 will likely be painted GREY with two valve covers ,How ever if you are color blind it could be brown or pink or yellow or painted intentionally a different color ! If so identifiable by two valve covers! Gray check the screen at the cooler pipe Red possible injector cup issue! as you have checked the EGR cooler!

Injector cups!!!!

Intake screen at the oil cooler pluged?these have caused a lot of greef at times

Yup agree with Trent fairly normal however if you find that temp is coming on faster than normal could be you have a boost leak!

Settings need to be enabled in the software not really reprogramed but changed!

yup high on the list of suspects!

By the way those sols are available THRU PAI ! not totally extinct yet!

They do offer the choice of distinctly different ENGINE Paint color How ever! That sets Us Worlds apart from them! Green or RED what should I choose! hmmmmm!

OOPS

They have done better than I expected on the plug issue I had expected they would have done it by now I'm surprised they are still willing to continue on with thes smoke and mirrors game! ( When ) it happens thou I won't be surprised! THE Evil swedish aggressor!

As stated checking the h ring height is in order here also you might consider looking into the ceramic up grade!

Cup issues ! They claim to never have problems !
