took a look under the car today, saw some oil leaking from the transmisson. the area that’s leaking is right on top of the front sway bar. not motor oil but a very thick oil almost like gel. anyone know what that is? can i still drive the car? any help? thanks

 

BTW, I have HKS Twin Plate

 

well its overfilled or your output seal or housing is leaking

 

took some pic of the leak, do anyone know what is broken? the seal? how much do u think is going to cost me? can i still drive the car? what needs to be replce, thanks all

 

more

 

come on, where is the guru when i really need them, haha

 

it is probably an o ring that was left out...

 

But i did my clutch like 1/2 year ago and never a problem, why just now?

 

Looks like a seal for the cv shaft, if the leak is coming from where the shaft enters the housing. The fluid would be tranfercase fluid,( thick, smelly, like sulfur) because the open front diff is driving that shaft. There should be a dust seal and a fluid seal right there. Seal replacement might not be too costly, although I am not sure what it entails.

 

anyone have part number for the seals? the guy that works on my car is not here until next week, just want to get an idea of how much it cost. I would assume only the shaft have to come off, not the clutch and tranny. Right?

 

I am thinking this is the part where is leaking, but i don’t see any seal part# on the service booklet

 

I am with everyone that thinks it might be the seal of the CV shaft

 

i think so too, is a very thick oil that’s coming out. do u think i can still drive the car or i should just leave it for now?

 

If it is leaking where the shaft is inserted into the housing, then the seal would be in the area of # 13 in the diagram. If the leak is on the left hand (drivers) side. #13 is a circlip that holds the output shaft into the driveshaft. Pressed into the housing should be the afforementioned seals, like a rear main seal in an engine. I haven't spent much time under my evo, but the seal should be able to be replaced after removing the drive shaft. See how much the part is and talk to your mechanic. If you can get under the car for a closer look you might be able to see if the seal is damaged. Use some brake kleen to clean the area and inspect it with a flashlight.

 

If the car drives OK , it can be driven. But I would be wary of how much fluid was lost and of debris getting into the case. If you live in NY, I know there is a lot of junk on the roads. And from your pictures your undercarraige is pretty dirty. So drive out of neccesity/emergency, but personally I wouldn't be joy riding.
