Look at these pictures with me, please.

So I was under the car trying to fix the emergency brake to hold better. I moved the supra so that it would be backed into the garage and when i was done i noticed a 4" in diamater spot of oil or tranny fluid or something from where the car was previously sitting. So I get under the car, clean things up a bit, and take these pictures.

It seems like it may be coming from this thingy.

But I also noticed this had some oil residue around it...

The first few pics are of your clutch slave cylinder.

Check your clutch master cylinder to see if it's low. Also, how is your clutch working? If it's too low on fluid, you will feel it not disengaging all the way.

Looks more like oil leaking down from the back of the valve covers, and running down the side of the transmission.

 

[BorHor]

WOWOW rust. something I never see in cali cars.

 

[TurboFreak]

deaboni - I'll go check right now. Brb. EDIT: Yep, little low. Not bone dry but needs some in it.
Cuel - Not valve covers. 100% positive.
Bor3000- THAT is barely any rust. Except I dunno why the oil pan is all rusted. Never seen that on any of my supras. Must be from it never leaking. LOL

So I let it sit for an hour and there is nothing on the ground... Weird. There is some slight seepage from the place in the last pic. Also, the slave cylinder isnt leaking it self. The oil is coming from the boot thing that is connected to the tranny.

ALSO, how do I check my tranny fluid??? It must be low... EDIT: I guess I check it with my master cylinder....dee dee dee.

ALSOOO, is the ACIS valve supposed to be open or closed when I check it. Mine is open...

If its coming from the square boot on the trans., it's possible that the trans. is leaking in the bell housing. Maybe the front bearing retainer gasket.

On the driver's side, about half way up the trans. is a fill plug. Center of the trans. case, just forward of the back up light switch. That is where you check the fluid level. It should just drip, or be right at the bottom of the hole when cold.

That last pic is the weep in the front of the bell housing, right at the inspection plate? If so, it's possible the rear main seal is leaking. You need to verify if its motor oil, or gear oil from the trans. You can remove the inspection plate and take a peek in there. If there's oil all over the inside of the bell housing, coming from behind the clutch, its the retainer. If it's running down the back of the motor, and the motor side of the flywheel has oil reside on it, its the rear main. Either way you pull the trans. to fix it.

Bet you wish it was the valve covers now, hunh?

 

[TurboFreak]

Man, I bet thats what it is...

Off to go check the trans fluid level...

EDIT numero uno : Would the car need to be on for that gasket to be leaking? I sat in the car and pumped the clutch for about a minute and nothing is leaking EDIT#2: I guess it would need to be on. I'm gonna go take off the inspection plate right now.

I edited my last post(hit the reply button to soon), so you might read it again...

No, it shouldn't need to be running for the retainer to leak. Could be a really slow leak, though, so it might take a while. The car does need to be running for the rear main to leak most of the time. It could also be the oil pan gasket. Take down the inspection cover, and peek in there with a flashlight and a mirror, if you have one.

 

[TurboFreak]

K, so i took the four bolts out of the inspection cover... won't come down. Do I pry and pull at it or is there something i missed?

Also the bolt closest to the slave cylinder is covered with fluid...

And I forgot to mention all this fluid does not smell like motor oil. Its def. tranny related.

 

[cuel]

The cover may be a little pinched by the motor and bell housing. Sometimes they're a pain to get out. iirc, there is a rubber gasket on top of it. It might be hanging up on the oil pan or something.

So the fluid smells more like gear oil? It will have a thicker consistency than motor oil as well. How was the fluid level?

 

[TurboFreak]

Yeah it smells like gear oil. And i need more tranny fluid.

ALTHOUGH, I was just thinking. The car was faced nose towards the back of the garage and then i moved it so it was facing out of the garage. Then I noticed the little puddle of oil that was just outside of the garage. I don't know what I was thinking at first but it couldn't have come from the front of my car....

So I dont think this leaking problem is as serious as I thought LOL. Oh well, good to know whats leaking, even if its a tiny bit.

SOMEONE in my family has some serious leakage though...or someone spilled something.

So I'm just gonna put more fluid in the tranny and call it a day.

I've lost the front seal in a couple of w58's over the years.

 

[cuel]

Might slip back under there and take a look at the ear end. Might need some oil there to

 

[TurboFreak]

Maybe. Although I was just under there fiddling with my E-Brake and didn't notice anything leaking.

Just for clarification (as I'd hate to see something get messed up), the fluid in your clutch master cylinder and the gear oil in your tranny are two different types of fluid. They are independent of each other, and are NOT one in the same.

The clutch is filled from the clutch master cylinder, and the tranny is filled from the fill hole on the side of the case. (Although I have seen posts about removing the gear shifter and filling the tranny from inside the car).

 

[TurboFreak]

Well update. Thecar IS leaking from that inspection plate. And it is definitely gear oil.

I filled up the transmission via the fill hole on the side of it with GL-5 specified gear oil. And i need to get fluid for my clutch master cylinder.

 

[suprarx7nut]

Leak from inspection means dropping tranny to fix... bummer.

Though my rear main was probably leaking for quite some time before I got the car.

I'd suggest Harbor freight if you need a tranny jack. (makes things infinitely easier when putting it back on )

 

[TurboFreak]

Yeah, I guess I'll fix that and do a clutch, come tax return time.

 

[Figit090]

uhhh...sorry if this is an obvious question (i said i'd go to bed 30 minutes ago and didn't...oh well) but..

how do you check the tranny fluid level... there's no dipstick...do i take off a plug and make sure it's at the plug?

 

[IJ.]

Manual trans yep undo the plug half way up on the right side, when Oil just dribbles out it's full.
