Picture is from underneath the car. I was doing some work on the Mini (2016 MCS, Auto, ~56k miles) and noticed this slow leak. Where is this leak coming from? Maybe 3 months ago I noticed my coolant was low, and I had a really slow leak under my car, maybe a 5 or 6 drops over night. It never came back after I refilled my coolant so I just left it alone until I had time to deal with it. I also noticed that there are some drips of coolant on the oil filter housing.

What's leaking and how much fun am I going to be looking forward to for this repair?


Spotted a coolant leak. It's flowing in the direction of the arrow.

 

Coolant on the oil filter housing is probably just that, bad oil filter housing. Common area to leak. Plastic housing gets distorted. Requires replacement.

 

Oh, I see, I didn't realize coolant goes through the oil filter housing. Is there a "how-to" someplace on changing the oil filter housing? I couldn't find one.

Do some searching I remember more on this issue in other threads

 

Thanks for digging those up for me. Yeah, this doesn't look like a task I want to do myself. I just finished changing a motor mount, trans mount, and intercooler. I'm sick of working on my car for a while lol.

 

+1 that oil filter housing i bet leaking coolant. We have the metal version linked in that thread.

 

NamBot3000, No problem.
And as an aside, I recommend ECS for parts and accessories

 

So after receiving some quotes, it looks like I’m going to be doing this job myself. Is there anything else I should change or anything I can upgrade while I’m there?

What all do I need for this job?
- Oil filter housing (metal version) - does this come with bolts and seals/gaskets?
- intake manifold gasket
- oil and filter
- coolant

​​​​​​​anything else? Is there anything I should buy simply because I’m likely to break it?
