Not sure exact locationWe dumped the oil and did another service - Drained about 12 gal out. Replaced with 10 as per manufactures spec.No smell of fuel in oil.Now we will run againAny thoughts Appreciate any advice as to a procedure to follow Nick Quote Link to comment https://www.bigmacktrucks.com/topic/30762-06-granite-oil-over-fill/ Share on other sites More sharing options...
hatcity Posted April 9, 2013 Share Posted April 9, 2013 just check level every day. (shouldn't be told to do this) 2 gallons over is stupid at the shop.

j hancock Posted April 9, 2013 Share Posted April 9, 2013 Like Hatcity said, check the oil everyday!!! Even if it is raining out.Add bumping the tires and checking of the lights EVERDAY!It is easier to fix a problem in the yard than on the side of the road.A couple of places the oil could be coming from. Grab a flashlight and start hunting if you see the problem again. 1 Quote JimIt doesn't cost anything to pay attention.

j_martell Posted April 9, 2013 Share Posted April 9, 2013 "never assume anything on a pre trip" are words i stand by (and damn proud of it). Id take working in the yard over working on the shoulder any day. Quote Lack of planning on your part does not constitute an emergency on my part....

Gmerrill0516 Posted April 9, 2013 Share Posted April 9, 2013 I'd hit the block with some gunk degreaser and wash it down to clear the oil. Keep a watchful eye as the guys stated and it should show up if you indeed have a leak. If all else fails, you can put some additive into the oil that shows up with a UV light. It shows yellow with the light and can help pinpoint the culprit. I believe it comes in a kit with a light. Your local outoparts store should carry it. Slack adjusters are critical too...a fire truck in boston area drove into a building as the last set of brakes had come out of adjustment leaving them with none...that was a few years back. The driver was killed if memory serves.Good luck.

farmer52 Posted April 10, 2013 Share Posted April 10, 2013 You may want to run an oil analysis just to be sure it is not fuel dilution. 1 Quote Ken PRR Country and Charter member of the "Mack Pack" Link to comment https://www.bigmacktrucks.com/topic/30762-06-granite-oil-over-fill/#findComment-177067 Share on other sites More sharing options...
rsb502 Posted April 11, 2013 Share Posted April 11, 2013 So what was the problem here? I see no need to do anything you shouldn't already be doing. You knew it was over when you got it, you ran it hard and it pushed some of the excess out. So I guess I see no need in unnecessary expense, file it right and it should be fine. If it "makes" oil then you're getting coolant in the oil probably from a bad oil cooler, but it sounds like it started over and tried to get to where it wanted to be.

I still recommend an oil sample/analysis if you continue to "make" oil. Cheap way to check the engine condition.

fjh Posted April 11, 2013 Share Posted April 11, 2013 Yup keep an eye on both ends the coolant and the trans I just ran across the beginings of one of these the other day! Fortuantly didnt wreck the trans yet! we ussually get em after the damage is done!

bbigrig Posted April 12, 2013 Share Posted April 12, 2013 Another way this series of engines has been known to "make oil" (more the fuel diluted type) has been through leaking o-rings at the Unit pump to block mating surfaces.In one case at a fleet I worked at, of a 15 truck order 2 of our engine blocks were replaced because the bore of the unit pump o-ring mating surface wouldn't seal. Both trucks made so much oil it was coming out of the breather at the front timing cover. The Mack dealer tried thicker o-rings to no avail. The unit pump bore on a hole was oversized. 1 in each block. In some cases this will show signs of hard starting or loss of power due to poor fuel pressure in the feed cavity, but not in every case. As was stated before, if the level has been adjusted and she ain't makin oil.......Let that dog run.....

Doffer Posted April 13, 2013 Share Posted April 13, 2013 I was driving a detroit one time and it started dumping fuel into the oil. I looked out the passenger side and it was blowing oil out all over the entire side of the truck. Pulled over, pulled dip stick and it was overfilled, thin, smelled like diesel.Be careful your not getting diesel in the block. I know with the older detroits this was an issue, so it might not be your issue. (what i've been told anyways. could be incorrect information) Quote Link to comment https://www.bigmacktrucks.com/topic/30762-06-granite-oil-over-fill/#findComment-177776 Share on other sites More sharing options...
Daron Foster Posted May 11, 2013 Share Posted May 11, 2013 NICK DID YOU ever find your problem with the oil being over full?I have a 2006 cxn 613 tractor that is doing the same thing.The shop will change the oil and within 1 week it will be over full and also the oil pressure will be around 20 pounds below normal.

Daron Foster Posted May 11, 2013 Share Posted May 11, 2013 our shop swears up and down theres no fuel in the oil because they cant smell it.i agree with you though,I think there is fuel in it,weekly oil changes are getting expensive .

topo Posted May 11, 2013 Share Posted May 11, 2013 To check for diesel in the oil you can put a drop of oil off of the dip stick on to a hot turbo diesel will evaporate real quick and oil will not .

thomastractorsvc Posted May 11, 2013 Share Posted May 11, 2013 if you have a Speedco close, they do oil anyalize for under $20 bucks on site and you can bring the sample or have them pull it, dont get your sample from the filters or the side of the leaky engine Quote Robert"I reject your reality and substitute my own."

staxx Posted May 12, 2013 Share Posted May 12, 2013 Places to check after oil sample confirms fuel in oil, unit pump O-rings , supply fuel pump the shaft seal lets go some times, end of fuel rail block plug behind front cover . have seen power steering pump shaft seal let go also but you would notice this if you checked powersteering fluid level. And if its coolant leaking most likey piston liner to counter bore or core plugs in head. If the oil cooler was leaking you would have oil in coolant because oil psi is greater then coolant psi. Do oil sample first only costs couple bucks and is money well spent Quote Link to comment https://www.bigmacktrucks.com/topic/30762-06-granite-oil-over-fill/#findComment-182874 Share on other sites More sharing options...
farmer52 Posted May 12, 2013 Share Posted May 12, 2013 As others and I said before....do a used oil analysis. Lots of value for a few $$.
