I have a max force 13 ( I know what your gonna say before you say it ) My driver said the truck revved up for no reason 2 different times. So I took off the pipe going to the air cooler and there was oil (kinda what I was thinking it could be) so there was oil and on the inlet side the pipe had a puddle in the intake.
So my question is (two turbos on this POS) Im guessing I need to take both off to see which one is leaking or is is the one on top and
which turbo is the high pressure and
which is the low pressure?
Does the new turbo need to be calibrated?
I asked the parts guy at RUSH when I called to get a price and he said NO you just bolt it on is the true
Heavy D your you out there?
MaxForce 13.. need help with turbo question

Ok, you need to be specific about how it revved up. Those are suppose to rev up on their own to keep warm. If it was cold outside, then it was probably normal. There should be no oil in the piping, but if that oil did cause the rpm increase, the engine would have ran away. The upper one is the high pressure, they do not need any sort of calibration. R&R.
spsauerland and Mad dog logistics llc Thank this. -
I found comments on another post you helped on which I think I know the direction Im going. My driver said the truck revved up for a second then went to normal. I know when its cold they rev up (thats when we hit the cruise) Mine use to do it all the time until I changed out the fan hub now its fine.
As for turbo yes there is oil in the pipes there was a pool on the intake side (drivers side) of the motor and you could tell it was making its way up to the motor and then running back down to the lowest point of that pipe to pool. So the HP upper turbo is what Im going to change with the cartridge and the supply line (why not for 100) pay now or pay later usually paying now is cheaper then later. 931.40 for cartridge 100 for line.
Found info on this
HP turbo blew, need removal tips and advice
As for the Rev up could it be some of the oil was making it to the combustion chamber? -
For it to rev only for a second and return to normal doesn't sound like oil getting in there. Once enough oil starts this process, the engine runs away.
spsauerland and AModelCat Thank this. -
Ok not sure what caused it then. My driver said it revved up and went right back down. I was thinking some oil was getting in the combustion chamber and that was causing it. Had to be a pro star gremlin it was wet out and I have had a ton of faults show up when its was pouring and truck runs crappy then it drys up and runs fine so maybe it was that. This truck is going to auction in the next month! Bought it for 10,000 put a 100,000 on it so I made my money back in the first 6weeks. Lesson learned.....
Heavyd Thanks this. -
It is not very likely it is the low pressure turbo. I worked on Maxxforce engines since 2012 and I’ve only seen a few low pressure turbos leak, high pressure leaks all the time. (The big one on the bottom is low psi, that’s also a pain in the ###.) you can get the center section and the compressor aide as one piece International calls it a turbo cartridge, the oil supply line is one time use, and if it has not been updated it will require a retrofit kit. You can tell if it is T’d off to the oil pressure sensor it is the updated version if it goes into the block towards the back of the engine it is old style. If someone has reused the oil supply line in the past that can starve turbo for oil and cause failure, because the reason they aren’t reusable is because when the weaved black part between the steel part of the line is bent it causes an internal restriction. As far as the revving up I would check that there are no engine overspeed codes. I have never seen one rev up just for a second.
Edit: I am assuming this is a 2010 emmisons not a 2007 -
These engine sort of think on their own. Rattle like crazy then go away. It has a closed ventilation system. If the oil separator is stuck open or clogged it will let oil into the intake system. Since it’s a closed system the crankcase fume is returned back into the intake system .
