Oh NO !!!!! TSB on the LS3 oil pump
 
So the other day i was going for a little drive. when warming up the drivers info center tells me "LOW OIL PRESSURE" "TURN OFF ENGINE":mad0259:and i look into it at the dealer and theres a bulliten saying there is a concern about faulty relieve valve inside the oil pump that means no oil to the top of the motor, thank my lucky stars that i was at home and did'nt drive or run to long without oil.G.M has not come out with a revised part# for this fix so i bought a standard volume /high pressure pump from MELLING and all is well.:thumbup: Don't have the T.S.B. # here at home. if you can't find i'll post it up when i get to the shop.

not sure thats true. they should have still done the TSB for you... If its a known issue (flaw) it shoud be covered regardless of mods. For example, if your tail shaft fails, you get a new tranny no matter what mods you have done b/c the part is a known issue...

It also includes the L99 engines as well...not just the LS3.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:

Some customers may complain of low oil pressure, no oil pressure, and/or engine noise, which may be the result of a sticking oil pump pressure relief valve. In some instances, this may occur intermittently if the valve frees up when the engine cools down.
Recommendation/Instructions:

If SI diagnosis isolates low mechanical oil pressure at the oil filter housing and oil pressure sensor, replace the oil pump, flush the oil cooler lines (if equipped), clean the inside of the oil pan, change the oil and filter, and re-evaluate the concern.

Notice: If an engine noise is noticed after replacing the oil pump, follow the SI diagnosis and repair the engine as necessary.

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.

So should we take this in now or wait till the light comes on and the motor may be bad?

I don't think the dealer will do anything until theres a problem.

How can we find out if our vehicle is part of this group of cars ?

The pump is approx $120 aftermarket, but any idea the price of labor or amount work needed if a person did it themselves. In the last year I just made the warranty on the stepper motor going out on my silverado's speedometer, then spent $600 twice replacing the lim gasket on a 2001 lumina and grand am. Kinda getting tired of spending money on problems gm knows about. $600 is easier to spend than lose the original motor that came with it.

SSMickey 03-23-2010 07:29 PM

Does anyone know what the VIN range of the affected cars is, or is this an across the board concern?
