    oil leak

    I had alot of oil underneath my car so I decided to clean all of it with degreaser in order to pin point where is the leak coming from.

    I found out that I have a small leak all around my oil pan gasket area. I also found out a leak in this area:



    I'm thinking that it could be the seals leaking, that will require to lower the tranny to change them, but it could also be part of the oil pan leaking in that area too. How hard is it to change the oil pan gasket in our LS1's? or should I just crank the bolts a tad and see if it stops leaking? Thanks.

    I am thinking rear main seal. You will have to drop the trans to replace the rear main seal and if you replace the oil pan gasket, you will have to lift the engine off the mounts.

    I know that to change the rear seal it requires to drop the tranny. My friend mechanic told that's around 300 dollars.

    Take a saturday and just do it yourself, looks like your rear main is leaking like said above. Normaly when its just the pan you get a few drips not a puddle..

    I never had taken a tranny out by myself. I kinda know how need to be removed but I don't have the room and/or necessary tools to do

    I know is not that complicated.

    without having dropped a transmisison before, you really shouldnt do it by yourself, as it requires some interesting leverage. at 5'3, weighing in at a whopping 103... ...if i can drop a transmission on my back, then so can you! lol, honestly though, i just put the car up on blocks, got a trans jack attachment and went from there. of course, i had a buddy to assist and make sure i didnt get crushed, but it wasnt too horrible. putting it back in was the difficult part

    Don't take me too seriously. Nobody else on this site does...

    FWIW, while I had a shop for 6 years back in the 80's and worked on cars quite a bit prior to (and after) that I pay others to do (most of) the work these days.

    I'm old and well paid...

    that nice Morning that you were able to do it. You said that you use a tranny jack? how high does the car has to be to clear the tranny? How do I set up the tranny jack? I might tackle this if I get the jack and if I can get enough clearance for the tranny to come out. Do I need to drain the tranny fluid? how hard is it to put back? Can you guide me thru the process?

    welp, i had the car up like this



    to get the trans out, you gotta first drain the fluid then you gotta pull the driveshaft out, then comes the trans. then you gotta deal with your torque converter. i used an awesome method of labeling cups with all the bolts that i took off so that i would remember where they went.

    im the kind of person who doesnt see any sense in doing all that work to remove all that stuff and putting the same stuff back. soooooo, this gives you the perfect opportunity to do some upgrading

    *but, im also that kind of person who is so small that they can fit their arm all the way up and replace that one 'tricky' trans bolt that so many places just leave out

    honestly though, if your buddy quoted you 300, id prolly go with it. buying a jack and the tranny attachment is gonna cost you about that anyway. the only reason why i even attempted this is because i was doing everything else myself anyway. not to mention that the torque converter can be a tricky process and if you dont do it 'just right', youre really gonna mess things up. i learned this the hard way when my dad insisted on coming to my house, in my garage, with my project and taking my tools out of my hands so that he could finish it.
