Thanks for the replies guys. I'll have roll under ours again to see how much hassle it will be to jack the motor up. I assume I just have to remove the motor mount through bolt on the drivers side to tip the motor up enough to get to the adapter. The local shop that replaced the lines with stuff from NAPA less than a year ago tried to tell me it's the rear main leaking nothing that they did and had the nerve to charge me $40 for an estimate. I won't be going back there anytime soon. The rear main is fine, this Blazer only has 78K on it and never over filled with oil.
