R.E.D Posted April 4, 2016 Share Posted April 4, 2016 For the past 3 days I have been running the truck fairly harder than usual. Averaging 58000 gross weight and doing 60 to 70 mph.Since I have 4.17 ratio truck was running at around 1600 to 1700 rpm.Once parked i saw the breather dripping and some drops on the ground and oil was way low....is this normal or am I looking at an inframe?Truck was inframed 60,000 miles ago.

fjh Posted April 5, 2016 Share Posted April 5, 2016 Was the inframe done prior to you owning the truck! if so what parts were used? Quote Link to comment https://www.bigmacktrucks.com/topic/44656-oil-consumption/#findComment-329588 Share on other sites More sharing options...
R.E.D Posted April 5, 2016 Author Share Posted April 5, 2016 Well kinda yes and no.i test drove and after seeing how bad the blow by was I asked them to overhaul it .not sure what parts were used .before the overhaul the blowby smoke could be seen from inside the cab when stopped at a light. It also had that burnt oil smell which is very distinctive.

fjh Posted April 6, 2016 Share Posted April 6, 2016 DId They use Mack mussel loader kits or jobber parts? Quote Link to comment https://www.bigmacktrucks.com/topic/44656-oil-consumption/#findComment-329680 Share on other sites More sharing options...
gearhead204 Posted April 6, 2016 Share Posted April 6, 2016 have a monometer test done to check the blow by, it could also be air compressor related or possibly a turbo shaft seal on the compressor wheel side Quote Link to comment https://www.bigmacktrucks.com/topic/44656-oil-consumption/#findComment-329686 Share on other sites More sharing options...
R.E.D Posted April 6, 2016 Author Share Posted April 6, 2016 Compressor is fairly new and no oil on the air tanks or dryer.im guessing if it is the turbo , I can just simply remove the pipe from compressor to charged air cooler and see the oil if seals are gone?

fjh Posted April 6, 2016 Share Posted April 6, 2016 (edited) Yup IF the oil is going in or out of the turbo It will likly so on the in or out pipes! How ever if you are standing in a cloud of blo by gasses while standing next to the truck think the answer is clear! (Note We Have had problems with the mussel loader kits being assembled poorly The rings not positioned correctly!)
