So this isn’t good, right?

[Writefast]

Crawling around for the first real time under the Yuke just now and found a LOT of fluid. Oil level is perfect. Haven’t checked trans yet.

 

[strutaeng]

No, not really. Could be a few things like oil pan gasket. Worst is leaking rear main seal because transmission has to be removed...:-(

 

[Writefast]

Tans looks like it is WAY over full. Pictured is engine cold and running.

 

[donjetman]

Yes it looks overfull.
Tranny has a vent hose. It will be wet near its exit.
Tranny fluid (atf) it suppose to be red.
I don't think tranny fluid (atf) coming out its vent hose would be that high up or that far forward.
You probably have multiple leaks.

VLOM, valve covers, oil pan, rear main, oil cooler plate. I would start at the top and work your way down. Try to get a light and take pics of the rear top of the motor for a leaking VLOM.

@Writefast It's certainly not a new vehicle but if it's not leaving puddles on the ground I wouldn't worry about it.

Could just be valve cover gaskets, there isn't really anything above the starter other than the valve covers.

So the top side on both sides is dry. Pic one. Pic two. There is a bolt, a tiny white dot dead center that pic, that is wet.

A "lot" of oil would be a puddle on the ground to me. Could this be the oil cooler plate maybe?

 

[Writefast]

Thing is oil level is and has been consistent. I’m thinking it’s dirty trans fluid but I’m also a stupid monkey. lol.

And an aside. Should my, what I think is the flywheel, be exposed to the elements like that?

You are asking about the inspection round cover missing? I thought you'd removed that to take a peek inside...

the last pictures you provided are only of the drivers side
aside from that yes there should be a inspection plate over that hole in the bell housing, but what you want to do it look up in there with a tilting mirror and a flashlight and see if the rear main is leaking or not.
It could be the oil filter housing/gasket/block off plate.
under there oil blows all over everything so it can be really hard to say
you can spray some degreaser all over under there and pressure wash it and then drive it a bit and then look again for fresh oil.
no sign of transmission fluid even if it is over filled, that is a small oil leak

 

[Dustin Jackson]

@Writefast unrelated but one of your exhaust manifold bolts is either missing or broken off.

Both of your pictures are from the driver side and your starter is on the passanger side. Your starter had oil dripping from it which has me curious.

On the driver side you have the oil filter and oil cooler that coil leak.

In the center you have the rear main seal, oil pressure sensor, and valley cover that could leak.

And then on both sides you have the valve covers that could leak.

There is supposed to be a little metal cover that pops in there and prevents the flywheel from being exposed like that.

Taste it. Seriously.

 

[j91z28d1]

how many miles on it?


grab some brake clean and spray it all down.. best if you have an air compresor to blow dry, no worries if not. and then keep an eye on it.

from the look of it, I'd best money on oil pan gasket. gasket is fine but gm seals the corners with some kinda rtv that starts seeping and slowly gets worse..

you could check the oil block off plate above the filter, but watch out trying to snug bolts, they torque at such low spec is a little above finger tight lol and if you strip anything it makes everything a 100times harder.

Nope. Was that way I guess since I bought it about a month or so ago.

Roger that. Ill buy some degreaser and I have a telescoping mirror for work.

 

[j91z28d1]

I'd love to know what oil vs atf tastes like but I don't want to test to find out

All old, good mechanics can tell the difference. They've even tasted antifreeze.
