Unhappy rear engine seal ain't work'n so well no more

I've got some engine oil seeping out between my engine and bell housing so logically it would seem to me that my rear seal has bit the dust. I'd like to just yank the tranny off and replace the seal with the engine in the car. My Mazda manual doesn't go into this kinda detail but this is doable right? By my calculations it should cost me about 6 bucks for the seal and hundred bucks for the tools. While I'm at I figure I'll replace my clutch and my noisy thowout bearing too. Are their any caveats I should be aware of when replacing this seal? Should I replace the pilot bearing too I hear it's a real PITA to pull out? TIA

wouldnt you rather take the whole engine out if your going to take the tranny off? i figure the workspace would be larger and it you come into more problems then you already have the engine out and somewhat apart.....but thats just my thoughts

i donot see why it could not be done like that..

rx-7girl is right though, unless you had a lift (or something like that) you will not have alot of room to work with.definatly could be done with jack stands, but not giong to be much fun

If you want to pully your tranny off, your going to have to get your drive shaft too, get fluid all over the place. Its a pain... goto advanced autoparts (something to that effect) and rent an engine hoist.

just take the damn tranny out...

the hardest thing is to take the flywheel off. You need the 2 1/8" socket and the air tool or you can use a really long *** tube as an extension.

I would change the clutch, pilot and throwout bearing and resurface the flywheel while at it. Don't take the engine out it's not worth it. The job should take you a weekend if you go slow and need to run to get the parts and stuff.

hope that helps man...I had the same problem...only problem I just left it as it was and changed only the clutch and pressure plate with some better parts ...I couldn't get the flywheel out...and since I'm building another engine everything will be out soon anyways.
