he used after market rings and sleeves not from cummins they are quite popular down here because of pricing...

After-market rings an d sleeves are never as good as factory components. Tolerances are not as good and materials are not either. That is why they are so cheap. I would never do that in an engine that I cared anything about. Jump over a dollar to save a dime.
Noted with thanks,

Fuel consumption way to high for 30-40 tons . Unless it’s constantly driving steep uphill or stop and go all day long. 4,47MPG . Oil pressure isn’t bad at all 38psi . What is at idle ?
Just curious.
You said WATER temperature. Do you meant to say antifreeze/coolant ?
741295 mls is about half lifespan for this engine (when is taken good care of).
Yeah .... about this aftermarket parts . Not a good decision.
Let’s see what’s the boost under full load and EGTs.

Thank you Wiseman
My apologies as I'm having to learn some of this terms used in trucking , at idle the pressure is 268kpa the fuel usage is stop and go what would be the ideal consumption the driver sent me a pic of a diesel leak on the diaphragm on the inlet side of the engine today , by water I meant coolant.

That is...well I’m speechless. It needs to be cleaned and fixed ASAP. You’re never going to find the leak with it that wet.


RE: ISX 475 oil leak - Rawze - 02-06-2018

Leak or not, That is the nastiest looking engine I have seen in a while -- I would suggest a power-wash and some basic TLC too. Those photos point towards a seriously neglected piece of equipment. If you would have showed up over here at my house with it that nasty and neglected, I would have run you off to go get it power-washed and steam cleaned first.


RE: ISX 475 oil leak - Wiseman - 02-06-2018

S53S , I’m puzzled. First you wrote oil pressure at 265kpa max and now you said 268kpa at idle . That can’t be possible , unless oil sensor or oil gauge gives a false information.
This nasty thing on picture looks more like an oil than fuel . Either case is in desperate need to be cleaned. Smear some on paper and see what it smells like.

Here @ Rawze’s you’ll learn fast and most importantly THE RIGHT WAY, so you can distinguish easily right from wrong.

Naahhh .... Rawze isn’t gonna run you off . He just gonna send you to wash it really good before he help you. He’s nature is like that . If he have the power, he can help everyone that ask . As long they listen , learn and don’t play smart ass .
The only problem I see is , you really gonna have hard time wrapping your truck in suitcase and fly from South Africa to Atlanta international .


RE: ISX 475 oil leak - s53s - 02-07-2018

Thank you Wiseman I will confirm the readings again via pics, @ Rawze all comments received with gratitude I wash the engine every week when the truck comes back using a 250bar pressure washer myself , I sent the pic to show you the leak, I came on the forum for help because the leaks are irritating me being a first time owner I don't expect sympathy though lol! The stuff does smells like diesel. I really wish I could send the engine there or get a recon , I'm sure I'll get all the help I can from this platform thank you guys!

Hi Wiseman,
I asked around about fuel consumption frim other owners and the best I heard from guys down here was 2,3km per litre on Cummins and 3km per litre with Scania. I noticed Rawze on a video saying he gets up to 3.7km per litre what could be the cause for such a huge difference

As per this post...

9.487 MPG = 4.03 kml. (google 'mpg to kml' converter).

It is because I drive slow (88-96 kmh), I drive in a way that maximizes fuel mileage, and my truck is set up + has programming designed for maximized fuel mileage above all else.

There are a lot of old posts on this forum where people discuss better fuel gains. Here is one that came up in a search ...
