Jag rear end leaking
 
Guys,

I have been working on my cobra now all summer and it is just about done. It has been a few weeks since I was able to get under it, but yesterday I noticed that the rear end seems to be leaking. The car has been on blocks with wheels on for about 6weeks.

I did not go under there to see where it is leaking. I do not have any experience with Jag rears. Any ideas, starting points, things to look for. Is it possible that since the car has been idle all season (from March) and up on blocks for an extended time a seal could have let go? some local guys told me to put the car down and see if it stops, that doesnt seem like a good fix to me.

All suggestions appreciated.

I am about to drop in my new Motor, and last thing I want is the read to go.

Mike

Maybe the rear cover gasket just needs to be snugged down a little.

It could be the rear cover seal as Rick says, but it could also be the breather being lose and letting oil drip out of there. Or worse, one or both of the seals on the halfshaft ends. If those start leaking you will get oil on the rear disk brakes, which on the Jag setup are inboard. Then you will have a braking problem like you were advised to check out.
I did get fed up changing those seals and decided to take the rear brakes outboard. That makes changing the seals much easier.
Strangely since I did that no seal went bad any more.

Did everything interchange pretty easy? My center section is from a Series 1, and I was thinking about putting the very later model outboard brakes on it. What did you have to change?

Thanks for any help.

I installed a rear brake kit manufactured by AMP. Check out my Gallery.
