Rsc1717 Posted October 21, 2021 Share Posted October 21, 2021 Hello trying to get some opinions on what’s going on here . Have a 2014 mack mp8 . I just noticed today that their is a leak by the transmission rear of engine . It’s on the passenger side right behind we’re the oil pan finishes. I seen the drip we’re the trans meets the engine so I followed up and it seems like their is a hole or breather on engine side and that’s we’re it’s coming from . What could that be any thoughts .

Rsc1717 Posted October 22, 2021 Author Share Posted October 22, 2021 I don’t think it’s a breather but I believe oil is coming out from their not a lot just a little and runs down to where the trans and engine meet .

Mackpro Posted October 27, 2021 Share Posted October 27, 2021 That hole is for the turning tool . Usually has a rubber plug filling the hole. Possibly rear main crank seal leaking if oil is coming out of it . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/68533-oil-leaking-out-of-rear-engine-breather/#findComment-481948 Share on other sites More sharing options...
Rsc1717 Posted October 28, 2021 Author Share Posted October 28, 2021 Oh ok yes it doesn’t have a plug on it and it is leaking thru their it seems like a slow leak will keep and eye on it . And possible wash the undercarriage to see if it’s coming from somewhere else. thanks mack pro Quote Link to comment https://www.bigmacktrucks.com/topic/68533-oil-leaking-out-of-rear-engine-breather/#findComment-482019 Share on other sites More sharing options...
