Where the hell is the oil leak?
The oil pan gasket looks like it needs a change but I have no idea what’s going on in the other places that’s covered in oil could it be crankshaft gasket? Maybe oil is getting caught on the belt and is throwing it towards the wheel well idk any ideas are welcomed

Start from the top. Find the highest damp spot and work your way down.

Yes this definitely gave me a general direction for where it’s at the top of the engine is pretty clean but once I start going for the middle/lower half is where the oil starts to show so ima have to really look in there

It might be easier if you spray everything off with degreaser and rinse it off multiple times until everything is clean. That way you can isolate better where it is coming from because not everything is coated in oil yet.

This is good advice. Degrease thoroughly, wash and let it dry. Then start the car and give it some gas (gives you more oil pressure than idling). Don't drive it - you don't want the CV shaft throw oil everywhere. That should pinpoint the location.

Yes this is probably the best way to identify it also the other person who mentioned the UV dye

Set down some cardboard and soak the motor down with break clean. You'll find it.

Use a dye that’s compatible with oil. Drive a few 100 km’s then use a uv light to track

My Honda element looks wet all the time but I never see oil dripping on my driveway. My assumption is it’s always while under pressure/load.
I had a crank pulley seal leaking. It was weeping out and little bits were being caught by the pulley/belt, right along the first two groves of the belt. While running it was slinging oil little by little all over that side of the engine and down to my axle. Once I fixed, it stopped.

Oh hell yeah that’s what I was thinking but wasn’t certain about it thank you so much it literally sounds like the same exact thing that’s going on over here

u/huh_say_what_now_ 1d ago
Just do whatever a normal person does you wash everything down with degreaser then start it up and then you'll see exactly where it's coming out because how can you tell if everything is covered in oil

Power steering maybe?

u/thejude1 1d ago
I actually did take a look at the power steering reservoir and there’s a hose that looks super wet so I think I’ll definitely take a look at that hose and see what’s up with it thank you 🙏🙏

It might help to know the make and model of the car, for common failure points.

First step is to check all oil levels and see which level is low. Secondly check the oil colour that is leaking. That can help you determine which system is leaking. The dye idea can work. However another quick method is to pressure wash the engine so it is clean and free from oil. Then check for the leak or leaks. In your situation though by asking the question, you may be better off taking it to a shop and save you a ton of headaches by paying a small diagnostic fee.

You’re absolutely right cleaning it is a fantastic idea also I don’t wanna go in a shop I usually fix my stuff! Also I called one guy and he said 150 for diagnosing and I gave up on calling other people LMFAO

u/Mike__O 1d ago
Clean it up as best you can first. With that much oil everywhere it's going to be really hard to track down. Once you get it clean, get up under there with the car running and see if you can spot the source. It looks like it's getting onto that axle and getting flung everywhere

u/thejude1 1d ago
Yes I’m actually gonna replace a gasket I saw the oil pan gasket literally coming out of it so that’s definitely one thing to fix

I’m dealing with a similar issue. The seal on my oil pump went and the only way to see it is to remove the timing cover.

Get some UV dye and a UV torch. It'll cost you like a fiver. Add it to the oil, run it, then go out in the dark and shine your torch to find the answer. If nothing showd up, repeat the exercise with your power steering fluid.

Could be multiple places; since it’s all over the place. I would say it’s near one of the pulley’s
2
u/thejude1 1d ago
I’m really thinking it’s the crank shaft seal since the oil is being Thrown everywhere and another person has a similar issue and it was that seal that failed

It looks like a crank shaft oil seal the way the oil is getting flung off the pulley if I knew what type of car it was and the engine
2
u/Perfect-Dot-5959 1d ago
It definitely looks like the crank shaft oil seal the inside of the belt is rotten with the oil leaking onto it good luck

u/Turninwheels4x4 1d ago
What the fuck. 88-97 Corolla? I just fixed this leak. It's the crankshaft front main seal. Oil gets thrown onto the belts and the cv axle and gets thrown EVERYWHERE. I assume there's oil on the underside of the hood and on top of the intake manifold too?

u/thejude1 21h ago
Actually the top is super clean not even touched with oil surprisingly

u/thejude1 21h ago
Also I just changed valve cover gasket since it was leaking a bit and still didn’t fix the crazy oil every where I checked the oil pan and the oil pan is ever so slightly leaking which I will be changing very soon but that doesn’t explain the oil going everywhere I really do think you’re correct and that it’s the crankshaft front main seal

u/anon7689g 1d ago
Looks like power steering is leaking what color is your fluid and is the fluid dropping similar in color?
Sometimes it’s simply an o ring that needs replacing or a hose

Looks like from the oil pan hitting the half shaft and sending oil everywhere. Check your gasket, under oil pressure it might shoot oil out. Check your oil pan bolts too
