Leak problems w/pictures!

[Morrow]

Hey guys, had a few random questions for you mainly regarding my leak but since I had the photos thought I'd throw them up here too. Im doing a clutch swap and Ill be replacing the rear main as it is leaking. Today when I had it jacked up I noticed some oil/moisture on the oil pan seal (drivers side only) and Im not sure if it is also leak, or if it is runoff oil from the rear main. Heres a few pics:

P is passnger, D is driver, some better looks at the driver side oil pan seal further on.

Red is showing the trail of leakage along the oilpan, yellow is also showing possible leakage or just from being dripped on.

Drivers side oil pan seal

Passenger side oil pan seal


So what do you guys think, replace em both (rear main and oil pan seal)?, thats kinda what im leaning towards although just based on the oil that is on the floor it looks just to be the rear main.
Had a couple more random things im not sure of:

Blue is a sensor that was disconnected when i looked at it, had no idea what is can anyone help me out? Red is another sensor unit I have no clue about it and want to replace it as along the circled yellow area it is melted as it was resting on my exhaust (hard to see in pic).

Here is an unknown bracket just sitting there besides a leaky power steering line, not sure what it is for anyone know? Blown up pic below

Just a pic of my CV boots, top one appears to be leaking grease, should I replace it?

Wow, alot of stuff going on there.

If you are doing the rear main seal i would do the oil pan gasket and oil level sensor gasket while you are there.

As far as that disconnected connector, im not sure what that goes to. The one next to it that i believe powers the backup lights.

Looks like that power steering line should be connected to the bracket.

As for the rack boot, I would replace it and when you have it off look inside to see if the rack seal is leaking

hope that helps

I have owned several foxes over the years and have spent alot of time chasing leaks and have come to a conclusion........ these babys just leak. Much of what I see in your pics is what I consider normal and wouldn't worry about unless you have some big puddles under the car. I'd give it a good steam power washing and keep an eye on it to see exactly where the leaks are coming from, then decide if I should do something about it or not. Rear mains seem to be the worst leakers and ALL oil pans seep... just the way it is. Yeah there might be a few guys out there who don't have any leaks at all, but it takes alot of effort to make that happen... I know, I'm one of those anal retentive guys as you can see by the pic below. Hahaha.

+1. If my mustang wasn't leaking any oil, I'd assume that it all leaked out.

My 89 was worse than that when I got it a few months ago. I had front seal leak...oil pan leak...rear main seal leak and the whole bottom of the car was oil soaked all the way passed the muffler. It was fire waiting to happen. I put it on ramps and soaked it down with Purple Power(good stuff). Then I spayed it down with my pressure washer...you can use a garden hose ...but it needs good pressure. It turned out looking good. I changed the oil using a thicker oil and LUCUS oil stabilizer / stop leak. It hasn't leaked a drop since. I'm putting a clutch in it today ...so I'll be doing the rear seal also.

I put my Mustang up in the air to see if I have anything leaking and the only leaks I had were the oil drain plugs I was excited lol

The connector in blue is probably for the NSS at the top of the transmission. The rubber connector plug is for the backup lights. The gray connector to the right has the white fastener that should be pressed into a hole in the exhaust bracket directly above the transmission cross member.

The brackets look like the routing brackets that hold the starter cable in place. The brackets are fastened to either side of the timing cover.

Looks like the oil filter is a little loose and some of the oil seeping out and is running down the filter and dripping onto the PS hoses.

Hit the entire underside with gunk engine degreaser. Drive for a thousand miles or so and then go back under and evaluate your leaks.


BTW, you don't have CV boots up front.

 

[Morrow]

Thanks for the input guys, yeah i kinda feel like a retard about the whole CV boot thing haha, im doing a clutch/rear main swap so i think im going to do the oil pan anyways it will make me feel better lol i know it is a pita though, was just wondering about the sensors, im pretty sure my reverse lights work, im guessing they wouldnt if that sensor was unplugged? I know my hazard lights dont work though could this possibly be that sensor? Anyone have a good source of all the sensor locations? Thanks again fellas.

 

[LiquidGT]

Just to start with, look for a round can shaped thing in the fuse panel, that's your hazard flasher.

that connector on ur tranny ur wondering about is the "nss" mine was broken when i got my fox and is still unhooked and my reverse lights work just fine that lose connector looks like an O2 sensor but i could b wrong. wouldnt worry bout the oil pan but while ur under there you might as well get it done. maybe some oil resistant rtv will suffice.

Yea whats up with the drain plugs leaking! I thought it was just me! When I rebuilt the engine I should have replaced the oil pan too (I just cleaned and painted the stock) because I have tried new drain plugs and plug gaskets and they STILL seep!

haha idk, i haven't replaced mine yet, I know the gaskets for them are shot so ill probably just get new ones of them and see if that cures it

looks to me like a 0 mile install! Is it still that clean after driving it? Morrow it's a ford it leaks. If it didnt leak then thats when you worryOR it's not a 100% ford! I just installed a new FRPP 351w swap pan and the dam drain plugs leak already! with only 1500 miles on it. If you replace the oil pan gasket pay the $40 some dollars and get the 1 piece rubber fail proof FRPP oil pan gasket! peace
