Gear oil leak 66 Corsa 4 speed
Posted by: Don1963 ()

I am about to pull the engine and trans from my corsa. I am fixing a leak coming from the bell housing. I know it is gear oil. What seals and or gaskets should I replace? I am also replacing the throw out bearing, because it squeals after the car sits for a month.I will be ordering the parts from Clarks. Any help with this will be appreciated. I don't know if it matters, but it currently has a 110 hp motor.

You should get the input shaft seal and a new pilot bushing to go with the throwout bearing.

I assume that you have confirmed the gear oil is coming from inside the bell housing and not being blown back from the differential or transmission selector shaft seal.

Also, look for a cracked snout coming out of the diff.

I haven't confirmed it is not coming from the differential or the selector shaft. I guess I will be getting that seal also. It does drip off the bell housing, but I don't know for sure where it is coming from.

Clean off the bottom of the bell housing and the bottom of the trans. Then start observing regularly and closely. May sound like a PITA, but way easier than dropping the power pack. Add a new pilot bushing to your list if you do drop it.

It may be coming from the seals where the half shafts connect to the differential. When I got my car and put new synthetic gear lube in mine leaked there. Still have the drip, waiting to fix until I do the u joints.
