Re: Significant oil leak

Thankz. I checked the filter housing, it is clean and dry. Wherever the oil came from is lower.

Re: Significant oil leak

I would suspect a rear main seal before an oil pan gasket. I would NOT expect the seal to be "blown," though.

Oil pressure is not a standard OBDII parameter as far as I know. Whether or not it can even be monitored depends on the factory sensor. Many (maybe even most) only have an oil pressure *switch* that will trigger the dummy light if the oil pressure dips below some ridiculously low number like 5psi.

Re: Significant oil leak

Do you mean that the rrar main seal could have leaked but will not continue to leak now that the level is adjusted?

The oil pan seal seems to be silicon instead of a gasket at least on the lower part of the pan.

i dont know enough about this new engine design to know if 2qts over would have been enough to submerge the crankshaft and cause aeration. All i know is the oil that leaked over the bottom of the engine and the extra 2qts we drained out didnt look frothy.

I guess i will drive it and maybe drive under boost for a bit too just before i put it on the lift next week to recheck it. Would boost pressure in the intake system have any effect on crankcase pressure?

To be honest, I'm not well-versed in diesel mechanics - nor do I know these engines very well (yet - as I haven't gotten my own to play with). I'm trying to learn as much as I can. But at this point I only "know enough to be dangerous."

For example, I just learned that the VM Motori diesels have an oil separator as part of the crankcase ventilation system. It includes a cam-driven centrifugal pump that's located on the front of the left cylinder head. I'm not implying that this could have anything to do with your leak. I'm merely pointing it out as an illustration of how little I actually know

My guess...other than additional gasses escaping around the rings from higher cylinder pressures under boost, the crankcase won't have a significantly higher pressure. The PCV evacuates the crankcase with suction from the intake so it shouldn't be much above atmospheric pressure if at all. Besides, as boost increases, so does intake vaacum.

Re: Significant oil leak

I left the skidplate and fiberboard off so i can see better. So far no more oil on the bottom of the pan but that is just putting it in offroad2 height and looking underneath in the driveway. I wont be able to tell for sure until later this week when i get it back on a lift.

Re: Significant oil leak

I just used some florescent oil dye on a buddy's truck and we were able to pinpoint the leak in under a minute. Give it a shot- it cost under $20.

Re: Significant oil leak

We will put it on a lift later this week to see if there is still a leak. If there is we will certainly use dye to locate it.
The dealership said if the oil aerated it would have triggered a low oil pressure warning light. The service manager claiming that air would not create pressure. I asked if he was sure about that because air would have been pumped with the oil, and compressed or moving air certainly causes pressure. He said that absolutely if the oil had aerated it would have triggered a low oil pressure warning. He also said that when the owners manual stated that overfilling can cause aeration and engine damage that 2qts over wouldnt have caused that and it would take close to double the proper amount of oil to cause aeration. Seemed like bullshit to me. I filed a case with Chrysler customer service just in case there are lingering problems.

Re: Significant oil leak

Just a thought, where exactly is the oil filter on these? I'd check there from past experience. Dealer's tech didn't screw it on right on my past vehicles and there goes an oil leak.

Re: Significant oil leak

Hmm, well the dye previously mentioned is not a bad idea.

Re: Significant oil leak

There is the possibility it was leaking out of pcv or other orifice and will stop leaking now that the level is correct. So we will inspect the bottom of the engine on a lift again later this week and see if the oil is still leaking. If it is we will use the dye. If it is not still leaking that should mean it was overflowing and didnt cause a leak that requires repair.
