I have included the link for the concerns I have.

Under carriage of an 07 F150 5.4 3V. I got under it cause I saw leaks after a transmission rebuild from the cooler lines to the cooler but now I saw the green drop at 12 seconds and I’m concerned. That’s my coolant, if I’m not mistaken but why is it in that spot? I also zoomed in on the oil drain plug and wondering why there’s black drops there? Like a slow leak? Checked my oil and it still looks new, changed it 500 miles ago and is still full. I also hear a little squealing but I can’t pinpoint it at all. Can someone help me with this? What should I do here? I degreased my undercarriage by the rack and pin because I got it replaced Monday. My mechanic informed me that my lower control arms were aftermarket and made in Taiwan but when I got under, I saw the Ford sign clearly stamped on both control arms. He was looking at them because I needed my ball joints replaced but he said the OEM ones I got didn’t fit and neither did 7 others he got. Did he just not want to do it? I dont think that’s it because I saw the squeaky ball joints he took out and put back on and they were mine. I feel like it’s about time I start doing these repairs myself with what I can and some help from you guys so any help in the right direction would be much appreciated!

Lets go after the coolant leak first. I am going to assume the leakage is coming from the front of the engine. A drop every 12 seconds or so sounds like an active leak. Check and make sure there is no leakage out of the weep hole (located on the water pump nose, bottom) on the water pump. Wipe the area with a paper towel and then place a dry paper towel below the weep hole and wait 5-10 minutes. Remove the paper towel, is it wet? If so you likely need a new water pump but make sure it is not seepage from one of the radiator hoses and dripping down to the pump area. Wrap dry paper towels around hose connections to check for seepage. A better description of the actual leak area would be helpful.

 

Yes green =coolant,
black = oil, usually
Red= trans or steering.

The best thing to do if there's no obvious leak is to clean the areas of concern as best as you can either by degreaser like simple green/ purple power and wipe/rinse or spray with brake clean.
Then once the area is clean and dry it's easier to see any leaks.
In general look up top for coolant leaks up by the heater hoses or intake manifold.
If you recently had trans work maybe that were stuff in the passenger side is all just residual spills from them having the trans cooler lines apart and from spills while refilling the trans via the dipstick .

Maybe the UPPER control arms are the taiwanese ones he was talking about?

 

The oil leak looks like the plug is leaking, can you tighten it up any?

 

Wipe off the anti freeze drop and watch it, the fluid might be sitting on top from the repair and has not fully drained off/down yet.
Though it could be from other things, wipe it off and keep an eye on it.

 

no, the old plug had the same issue so I thought it was the plug since the o ring on it wouldn’t move. This is a new OEM plug and it’s snug in there. I checked my oil and it’s not that black at all. Still looks new.

 

my coolant is yellow, not green so I wonder what happened that they put green in. I degreased it with some foamy gunk and I’m trying to narrow the leak down. I know my PCV hose is cracking and I’m replacing that Monday once I get it delivered. There was some weird dried substance at the upper radiator hose connection to the block and I’m going to look at that today. The trans is leaking at the cooler lines and it’s annoying because every shop wants to sell me a transmission, not fix the leaking.

 

im going to do this today. The leak area is right under the engine. Looks like by the starter but I’ll check it out again in a few and report back.

 

R134 has green dye in it that's the only thing beside coolant I can think of that's green. Your ac compressor is in that area maybe that has a leak?

 

Very possibly because in the video, you can hear a squeak and I can’t narrow that down could it be a bearing or the compressor itself?
