Hello, dear Honda owners!

I did a long read using advanced search, but failed to understand what is going on with my car!
The backstory: I have 2 cars - Mercedes E-Class for longer trips and a Civic for shorter trips in the city. MB broke down some time ago and I'm saving money to fix it(huge repair). Now I have a long(four day) trip planned next thursday and I need this Civic moving! I doubt I will be able to get this fixed in any repair shop that quick! So I have to try something myself ASAP until I find out if someone will be willing to take my car in after weekend!

My 2003 Civic EP2 D16V1 (European car) has developed a HUGE coolant leak and it seems to go down from the top of the rear side of engine block right above engine oil filter. When I looked at the pictures I was sure it is the electrical thingy located above oil filter that is leaking but I found out that is the oil pressure switch! That could not leak coolant, could it?
So what would make sense to me is that either there is some hose leaking behind the air filter box(cant be seen from top or bottom of the engine) or water pump has failed and is somehow leaking this way? I have read about a "weeping hole". Where is it located on my model?
Mostly this car is used by my girlfriend and she told me she heard silent squeaky noise coming from engine when it was started cold. When warmed the sound went away. This also could be water pump. I dont think I see any coolant around the waterpump tho.

Any advices!? Any ideas where this leak is originating from?
Any input will be appreciated!

I will attach some photos I took today. (please ignore the oil leaks and sorry for the large images)

 

Could be one of the rubber lines that attaches to that rusty water pipe above the oil filter, could be the o ring on the water pipe is no good. Your second picture shows the area best to look.

 

This is your water pump weep hole.

 

Turned out it was the rusty water pipe itself. It had rusted trough on the drivers side (coolant droplet on it can be seen on my 2nd pic.)

Thanks for replies to both of you guys!

I got the car to the workshop I usually take it and they did the job replacing the metal pipe with used better one and gave me back the car at 11am at the day I had to leave! Just in time to get to the hotel and check in time after almost 5 hour drive!
Used pipe was chosen because time for repairs was so limited! I would suggest using new one!

 

Change the oil filer. Looks like it need it.

 

I did already change oil and filter last friday. It looks worse than it is! When i took this image the filter had been on the car for 9000 km. I changed it at ~10k. Also intake air filter and cabin filter.

Another thing to mention is - all that black gunk on the left bottom side of engine block is not only oil leaks. Someone in the past has used some kind of rust prevention material on the car and also got some on engine etc parts lol. Mostly its gone from the rusty parts already.
