.... oil leaks

just came home after checking out all my oil leaks and i have several.
appears to be rear main
tailshaft seal and the o ring where the sensor goes in
front cover
valve cover

i may stick some tranny seals in this weekend. have any tips on sticking those in easy and without making a mess? i may wait a while on the rear main. also on the front cover i can tell if its the crank seal or where all its coming from. can i put a crank seal in without taking off the cover and without screwing up anything?

I chased oil leaks for awhile. Front and rear. I put a valve cover breather on and I think it helped. Forget about unmetered air and the pcm. I ran Datamaster and saw little difference.

Rear main- This is often confused with the rear LT1 intake leak. Requires removing intake and applying new RTV. Rear main rarely ever leaks. Slightly challenging.

Tailshaft seal and the o ring where the sensor goes in- Remove the driveshaft and replace it. Not too hard.

Front cover- Requires dropping the oil pan which often leads to damaging the pan gaset. Major PITA here.


Valve cover- So easy its a joke.

yea i may even take it and have it fixed just cuz they will warranty their work. its kinda hard to tell if its crank seal or waterpump tho. the whole damn car leaks. its weird cuz my 95 z didnt leak a drop. i may fix it all myself except rear main. i cant even park in the driveway when i visit my folks.
