Vmax owners inside....
Any other NNBS VMax owners have to take their truck in for rear main seal leaks? Mine's been in twice and needs to go again 
A buddy of mine has a GMC VMax and his is leaking as well.

Mine was leaking from the trip home from the dealer and has done it every since. Each time the rear main was replaced it would go away for a couple of weeks and start to leak again.

you may want to have them check it.... it may be the rear main cover.... those tent o leak, and have porosity problems with the cover.... they tend to end up being resealed with rtv.... that tends to be the solution to many mis diagnosed rear main seal leaks.... alot of techs just slap a rear main in there and think its good, they dont actually look for it....
you may want to request they put dye in your engine and drive it for a week or 2 and see where it is actually leaking from

Subject: Engine Oil Leak at Crankshaft Rear Main Oil Seal (Install Revised Crankshaft Rear Main Oil Seal Using Revised Rear Main Seal Installer and Remover Tools) #05-06-01-019F - (10/02/2007)
Models: 1986-2008 GM Passenger Cars and Light Duty Trucks (including Saturn)
with 2.8L, 3.1L, 3.4L, 3.5L, 3.9L 60 Degree V6 Engine (VINs D, E, F, J, K, L, M, N, R, S, T, V, W, X, Z, 1, 3, 8, 9, W, R -- RPOs LG6, LA1, LNJ, LG8, LL1 or LX9, L82, LL2, LB8, LHO, LG5, LB6, LE2 or LQ1, LH7, LC1, L44, LZ4, LZE, LZ9, LGD, LZ8, LZG)
--------------------------------------------------------------------------------
This bulletin is being revised to add an Important statement on proper seal installation. Please discard Corporate Bulletin Number 05-06-01-019E (Section 06 -- Engine/Propulsion System).
--------------------------------------------------------------------------------
Important: This bulletin only applies to 60 degree V6 engines. Some of the discontinued 60 degree V6 engine VINs and RPOs may have carried over to other new model year engines and may no longer be a 60 degree V6 engine. So this bulletin may not apply. It is very important to verify that the following information is correct before using this bulletin:
• Year of vehicle (e.g. N = 1992)
• V6 Engine Liter size (e.g. 3.4L)
• VIN CODE (e.g. X)
• RPO (e.g. LQ1)
If ALL the information from the vehicle (year, size, VIN Code, RPO) you're working on can be found under the models listed above, then this bulletin applies to that engine. If one or more of the vehicle's information can NOT be found under the models listed above, then this bulletin does NOT apply.
Important: This bulletin does not apply to 2004-2007 Saturn VUE models with 3.5L DOHC V6 Engine (VIN 4 - RPO L66) or 2005-2008 Cadillac CTS with 2.8L HFV6 Engine (VIN T - RPO LP1).
Condition
Some customers may comment on external oil leakage.
Correction
Important: Before replacement of the new design crankshaft rear main oil seal, be sure the PCV system is operating correctly.
Notice: The new seal described below comes with a protective nylon sleeve already installed in the seal. This sleeve assures that the seal is installed in the correct direction and also protects the seal from getting damaged during installation. Do not remove the protective sleeve from the seal; if removed, the installation tool (EN-48108) will not work.
A new design crankshaft rear main oil seal and installation tool (EN-48108) has been released. This seal incorporates features that improve high mileage durability. Replace the crankshaft rear main oil seal with the new design rear main oil seal, P/N 12592195, using the following service procedures.
Tools Required
Important: TOOLS WERE SHIPPED TO YOUR DEALERSHIPS. IF YOU HAVE NOT RECEIVED THEM OR THEY ARE LOST, PLEASE CALL GM SPECIAL SERVICE TOOLS AT 1-800-GM-TOOLS.
EN-48108 Rear Main Oil Seal Installation Tool
This tool has a unique design to allow the technician to easily install the rear main seal squarely to the correct depth and direction. Before proceeding with installation, review the above illustration to become familiar with the following components:
Mandrel
Drive Drum
Drive Nut
Washer
Bearing
EN-48672 Rear Main Oil Seal Remover Tool
This tool has a unique design to allow the technician to easily remove the rear main seal without nicking the crankshaft sealing surface when removing the seal. Before proceeding with removal, review the above illustration to become familiar with the following components:
Removal Plate
Threaded Adjustment Pins and Jam Nuts
Force Screw
#2 Self Drill Screws 38 mm (1.5 in) long 8 needed
Extreme Pressure Lubricant
Removal Procedure
Remove the transmission. Refer to Transmission Replacement in SI or the appropriate Service Manual.
Remove the engine flywheel. Refer to Engine Flywheel Replacement in SI or the appropriate Service Manual.
Install the removal plate (2) and both threaded adjustment pins and jam nuts (1) into the back of the crankshaft flange and secure the plate with adjustment pins and jam nuts.
Install #2 Self Drill Screws 38 mm (1.5 in) long, eight needed, (1) and tighten down flush to the plate.
Important: Before installing the force screw, apply a small amount of the Extreme Pressure Lubricant J 23444-A, provided in the tool kit.
Install the force screw (1) and back off both jam nuts (2) and continue to turn the force screw (1) into the removal plate to remove the seal from the crankshaft.
Once the seal is removed from the crankshaft, remove and save all eight screws and discard the old seal.
Notice: Clean the crankshaft sealing surface with a clean, lint free towel. Inspect the lead-in edge of the crankshaft for burrs or sharp edges that could damage the rear main oil seal. Remove any burrs or sharp edges with crocus cloth or equivalent before proceeding.
Installation Procedure
Notice: Do not remove the protective nylon sleeve from the new rear main seal prior to installation. The EN-48108 is designed to install the rear main seal with the protective sleeve in place. Never apply or use any oil, lubricants or sealing compounds on the crankshaft rear main oil seal.
Align the mandrel dowel pin (EN-48108) to the dowel pin hole in the crankshaft. Refer to the above illustration.
Using a large flat-bladed screwdriver, tighten the two mandrel screws to the crankshaft. Ensure that the mandrel is snug to the crankshaft hub. Refer to the above illustration.
Important: Different types (styles) of rear main seals were used in production in different model years, engines and manufacturing facilities. As a result, the NEW style rear main seal that you will be installing may have a different appearance or shape than the one removed. Regardless of what type of seal was removed and what side was facing outside the engine, the new seal must be installed as described. Upon close inspection of the outer lip on the new seal, the words " this side out" will be seen. This side of the seal must be facing OUTSIDE the engine when correctly installed. While this may seem backwards, it is correct. In addition, the protective nylon (plastic) sleeve that the seal is mounted on in the package was designed so that the seal can only be installed in the proper direction when using the installation tool described in the following steps.
Install the rear main seal (1), with the protective nylon sleeve attached (2), onto the mandrel. The seal, if properly installed, will center on a step that protrudes from the center of the mandrel. As an error proof, seal will fit only one way onto the mandrel. Refer to the above illustration.
Important: Before installing the outer drive drum, bearing, washer and the drive nut onto the threaded shaft, apply a small amount of the Extreme Pressure Lubricant J 23444-A, provided in the tool kit.
Install the outer drive drum onto the mandrel (EN-48108). Install the bearing, washer and the drive nut onto the threaded shaft. Refer to the above illustration.
Using a wrench, turn the drive nut on the mandrel (EN-48108), which will push the seal into the engine block bore. Turn the wrench until the drive drum is snug and flush against the engine block. Refer to the above illustration.
Loosen and remove the drive nut, washer, bearing and drive drum. Discard the protective nylon sleeve.
Verify that the seal has seated properly.
Use a flat-bladed screwdriver to remove the two attachment screws from the mandrel and remove the mandrel from the crankshaft hub. Refer to the above illustration.
Install the engine flywheel. Refer to Engine Flywheel Replacement in SI or the appropriate Service Manual.
Install the transmission. Refer to Transmission Replacement in SI or the appropriate Service Manual.
Inspect for proper fluid levels.

--------------------------------------------------------------------------------
Condition
Some customers may comment on an engine oil leak.
Cause
Upon initial diagnosis, it may be determined that the leak is coming from the rear cover gasket. This condition may be caused by engine block porosity on the sealing surface. This issue pertains to aluminum block applications only.
Correction
Follow the steps for Oil Leak Diagnosis in SI to determine the source of the leak. If the leak has been diagnosed as coming from the engine rear cover assembly, refer to Engine Rear Cover Replacement in SI and remove the engine rear cover assembly. Inspect for engine block porosity where the engine rear cover mates to the engine block. If porosity is found anywhere on the sealing surface, use the following procedure to apply RTV to repair the engine block porosity. Refer to the illustration below.
Important: Clean any residual oil from the block and cover before applying the sealant in the next step.
Wipe a small amount of RTV, P/N 12378521 (in Canada, use P/N 88901148), onto the surface using a plastic scraper to fill the porosity.
Remove any excess RTV material, especially from inside the high pressure oil passage. Refer to #1 in the above illustration.
The joint may be closed immediately after applying the RTV. Total joint time after the RTV has been applied must be under 20 minutes.
Important: Refer to Engine Rear Cover Replacement in SI and follow the tightening specifications and sequence.
Reinstall the engine rear cover using a new gasket and a new crankshaft rear main seal. Refer to Engine Rear Cover Replacement in SI.
