Oil leak near transmission / rear main seal

[therican]

It's definitely not lubricant, but I'll know today when they can check the OPS.

Has it ever been the OPS though

Here's the loaner (4k Miles, 2.0, '21)

And service advisor states all is normal ... yikes; oh and they wiped it off fml

Did you ask what the cause is and did they provide an explanation?

Yep and got nothing like... jfc; that shit ain't normal.

Oil leak near transmission / rear main seal

Yesterday I noticed an oil leak where the transmission meets the engine block. Judging from the location it could be the rear main seal. There are some corresponding oil stains on the top of the plastic shield. I plan to make an appointment tomorrow to have it looked at. My car has just over...

Yeah whats your point?

 

[tarhoosier]

This is a major mechanical job in time (to you) and cost (to Genesis, perhaps some to you) and for someone who is skeptical of Genesis competence in service the risk of their repair attempt might be worse than the other options.
Perhaps that has been the point of your posts. Dodge the full repair until some other resolution is available.

Revisited this thread today and prompted me to take at look under my 2019 3.3 Sport that is just under 10,000 miles. Couple of car ramps and a 10mm to remove the 6 screws holding the undertray in place. Yes it does look dirty and oily but its dry to the touch. Using a towel I wasn't able to remove much of the grime so at this point I'm going to say its a non issue for me. Posting a picture of the undertray as well, The bolt in the picture is right about where id expect to see any drips and nothing much there to note.

I changed my oil today and checked for this again (after cleaning it up last time). Sure enough, the bottom of the bell housing, around the "weep" hole is oily and there's a drop of oil hanging on the head of a nearby bolt. It doesn't seem to be coming from anywhere above. This is annoying, because it may be indicative of a leaky rear main seal, but I don't think I'm going to worry about it, since it's very slight and I doubt I'll have the car past 30k miles (it's only got 19,600 miles now). I really don't want the yahoos at my dealer pulling the engine apart.

Aw, that sucks... I see there is a Stinger forum post about a leaky engine plug seal. I also suspect it could be an oil pressure sensor at the top of the engine. In previous non turbo 6 cylinders, it can leak down the valley and come out in the same spot.

 

[Husky]

Interesting. Good info, thanks. I'd rather it was the plug leaking, of course, but will probably still leave it alone. Strange place for a plug!

Check this video.

 

[Husky]

Very interesting, thanks.

 

[Aquineas]

Check this video.

Soooo that video makes me have more questions for those who are more mechanically inclined. Are there long-term implications of not getting that oil-pressure switch fixed?

 

[rmod]

I am not mechanically inclined but the first thing that I'd check is what oil is leaking. Engine oil or ATF. (I recall someone in this forum had a shop where they did a bunch of transmission pump seal or something similar leaking a while ago). Irrespective of the leak source, if the engine and transmission works without any issues, you can keep running it by wiping off and topping off the leaking oil. This can be tricky if the ATF is leaking as it is a little tedious to check the trans fluid level compared to the engine oil. The leak may get worse over time as the seals start to stiffen up. Whatever you do, don't be tempted to pour in a bottle of stop leak or something similar.

Mine is a 2.0T and I have a similar "seep" that is going on since ~50K kms or so. I've traced mine to be seeping at a location where the bell housing meets the engine. Strangely, it is not leaking from the weep hole at the bottom. The car now has ~130K kms and it has not gotten any worse. I just spray break clean and wipe it off each time I change the oil. I've also started noticing oil started to seep out of the timing chain cover at several places and the valve cover junction is starting to get moist at several places as well. Once I noticed these other leaks, I stopped worrying about them.

Just did an oil change myself and checked -____- ~22,000 miles. Will see what the dealer says

It sure would be nice if Genesis found the cause of these leaks. I think they are pretty minor but would be good to know.

Is it a 2.0T or 3.3T? Just curious. My guess is it's engine oil, but the smell (or lack thereof) would easily confirm that. Lots of issues with the 2.0T engines over the years. Our 2023 G70 2.0T is due this week, and I'm a bit concerned about quality issues as of late. It should be a bulletproof engine by now, but it's far from that. It seems bad enough if that happened in just one oil change, but I'd clean everything real good, and check it next oil change, before deciding if you want a dealer to tackle that extensive job or not. Good luck.

I think most issues posted here are for 3.3 engines. Some pics look like weeping and very minor. Unless I had a full blown drip on my garage floor, I’d be wary of a dealer doing major disassembly for they may screw something else up. I need to change my oil too but my other car is on my lift right now for some maintenance so need to get it done first. Will post a pic of my 2020 undercarriage soon though.
