Someone said that the LSx motors are notorious for oil consumption and that the consumption in the LS4 is well within GM's "acceptable" levels.
In other words, they aren't going to do a damn thing about it.

2005 Pontiac Grand Prix
--------------------------------------------------------------------------------
Subject: Oil Consumption or Oil Found in Intake Manifold - keywords body cover leak rocker throttle #PIP3489A - (01/05/2006)
Models: 2005 Pontiac Grand Prix GXP
Equipped with a 5.3 LS4 engine
--------------------------------------------------------------------------------
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Engine oil consumption and oil puddling found in the throttle body or intake manifold area.
Recommendation/Instructions:
If a customer concern of oil consumption has been verified (more then 1 quart of oil in 2000 miles), the throttle body and the intake manifold should be inspected for excessive oil puddling. If there are signs of oil puddling in the intake area, remove the right rocker cover for inspection.
Inspect the right rocker cover PCV baffle drain back slots and the PCV baffle drain back hole. There are two drain slots at the bottom of the PCV rocker cover baffle and a drain hole located at the front (located towards the front of the engine when the rocker cover is installed) of the PCV baffle. The PCV baffle is sealed to the rocker cover with RTV. The drain back slots or the drain back hole may be blocked with RTV sealer. If the PCV drain slots or drain hole are blocked with RTV, the right rocker cover will need to be replaced. Evaluate oil consumption after replacing the right rocker cover.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

The bulletin did not apply to 06 cars (Pontiac or Chevy) for some reason. If I had more time I would look up valve cover part no.s....and see if there are any part no differences etc between 05 and 06.

![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
Hello all First of I'm new here and found this sight very helpfull ! I was thinking about this oil consumption thing . how likely would it be that this excessive oil consumption has to do with the DOD function? If the cylinders that are deactivated are still tying to draw air and fuel in and the intake valve is closed wouldn't that create a high amount of vacuum in the cylinder? If it does then it would try to draw air past the piston rings kinda like blowby. This air is directly off of the crankcase. Seems totally possible to me but i'm new to the LS motors . Oh yeah not to change the subject but. . . . . I just picked up an LS4 and plan on swapping it into my 85 fiero GT

It is a cause for Detonation due to burning oil in a combustion chamber causes carbon build-up. That carbon build-up become hot spots in the combustion chamber.
Best bet is to see if a LS6 Valley cover fits. This lessens the amount of oil that comes out of the PVC system. It basically moves the PVC from the valve covers to the valley.
Then add a catch-can. It will catch the excess oil that comes from the PVC system. You still loose oil, but it's caught in the catch-can and isn't burned in the combustion chamber or is coating the inside of the intake and intake ports.
