2001 se v6 manual

it leaks right through there on the bell housing on the transmission that is where the stick shifts gears I believe also it can be coming from more towards the engine because you can see a trail of oil that eventually makes it to the end of the bellhousing and pools til it starts dripping luckliy it is a little drip but it has gotten worse. I tried blue devil rear main seal leak and that didn't work. I don't know what to do if you have any idea please help me this truck has been nothing but problems I haven't even put 3000 miles on it it has 92k miles thanks

It's pretty hard to tell from the photos. You could have a rear main seal/oil pan leak on engine or an input shaft leak on the trans. Either way it is not good for the clutch. If it gets on the clutch you will need to replace it.

Can you smell it? I really mean it, take a good whiff of it. Gear oil smells distinct. Maybe compare it to the engine oil on the dip stick or find the trans fill plug and compare that. Other option would be change your engine oil with a colored oil and see if the leak changes color as well.

I will smell it tommrow when i clean under there i just showerd lol so i dont wanna get dirty again. I just changed the oil today the leak shouldn't be black anymore i am guessing ill clean and see if the leak comes out the same color. you think it would come out the same color if it is new oil? new oil is like a yellowish color so i am guessing it won't come out black. I wonder how much they would charge me at the shop for this.... thanks for the reply

It won't come out super clean either way. The inside of a bell housing is pretty filthy with the clutch dust flying around.

You'd be best off in getting a quote from a shop in your area for pricing.

I wish i knew if it was trans or engine oil because i know an engine oil leak of this size is no big deal but if the tranny runs dry thats going to be a big problem

Transmission "oil" is thick. That looks thin. Smell it, feel it. Or... check and see if you're low on engine oil or transmission gear oil.

 

[BigDad]

Top off the tranny oil, check at intervals, you should be able to notice if it's trans, before it gets critical.

 

[nealinnevada]

Have you considered that it is just the clutch cylinder leaking? Why not remove the fill plug on the tranny and stick your finger in there. You should be able to touch oil easily. Also, you could eliminate the tranny/engine by putting UV tracer dye in the engine oil. Get yourself a cheap UV light and check for the dye showing up.

Rear main seal and rear oil pan lip seal leaks are both very common on the VG's. Rear oil pan seals typically leak when parking with the nose uphill and while driving, but not while idling. Rear main seals will typically leak any time the engine is running. A lot of leaking rear oil pan seals get mistaken for rear main seal leaks. As mentioned, gear oil is very thick, sticky and smells pretty bad compared to engine oil. If the clutch slave is leaking, you can peal back the dust boot a little and clutch fluid (actually brake fluid) will pour out of it.

 

[Justwork]

I don't think it's the clutch fluid, with a leak like that the clutch pedal would feel pretty sloppy

well i think its the clutch slavecylinder I am going to change it will update when I receive the part

As mentioned earlier, you could pull the boot back on the slave cylinder and know if it is the source of the leak. If you find it is the source, be advised that generally cylinders begin leaking due to water accumulating in the system (the brake fluid captures moisture in the air over time) and the water corrodes the bore of the cylinder. Be sure to completely purge the system and then change fluid every year or two. This, more importantly, applies to the brakes too.

I just showerd

Way too much information !!!! Unless you showered with someone and have photos !!!


Really - anybody experienced could READILY smell the fluid and determine if it was really gear oil. I have practically no nose and can smell the sulfur-like odor of gear oil.

It doesn't look like the slave leaking to me. The fluid leaking from the slave wouldn't travel upwards, it would travel downwards and onto the bottom of the slave... easy to tell just peel back the rubber boot from the slave cylinder and if fluid comes out - it's no good.

In my experience transmissions rarely leak from the input shaft seal

I had that same exact problem with my truck - it was the rear crank seal. The back oil pan gasket was leaking also.

These are not repairs that you make until your clutch goes out. You put up with the slow leak until your clutch goes out

Then you change the rear seal along with the clutch job. Because The only way to change a rear seal is to remove transmission/clutch/flywheel

I did my rear seal and oil pan both at the same time as I did my clutch.

Rub the fluid all over your fingers and smell your fingers really good. Gear oil from the trans will smell very distinct and brake fluid from the clutch cylinder will also smell very distinct.

Old, used and dirty engine oil that has seeped down through the flywheel housing won't have much of a smell if you're not used to working on cars. So in your case if the fluid doesn't have much of a smell at all, then you've got engine oil.

We have a winner

I just looked at your pictures again, on your picture you can obviously see a trail of engine oil leaking out of the hole on the bottom mounting area of the bell housing of the trans

That's coming from the same place as your other leak coming out above the clutch slave cylinder.

Your rear crank seal is leaking and the engine oil is traveling all that distance to where you see the leaks both above the clutch cylinder and also through the hole on the bell housing

The engine oil is leaking out all inside your bell housing . It's filling up and those two places are the only places for it to come out.

Let it go until the clutch fails . Rear seal is part of a clutch job.

what you think is that the rear main seal is leaking?

 

[nealinnevada]

Yes, that is what is being said, rear main seal...BUT, if it was me, I would be 100% certain. I'm not saying it isn't the rear main though. I owned a 7.3l diesel for a lot of years and I saw numerous people replace a rear main seal when, in fact, it was oil working its way down the engine from a higher up location. Take it to a couple of reputable mechanics to verify BEFORE committing to seal replacement.

It's going to be black because it's passing through your bell housing with all that clutch dust before you actually see it. You need to smell it

it really doesn't have a spell I got the stuff between my fingers and sniffed hard.. I didn't smell anything. I guess it is motor oil... damn

i also cleaned down there. now it will take about 1-2 weeks to see the oil come though
