Hello JACUSTOMER, did this just start all of a sudden? How many miles are on the vehicle? Does the engine still drive fine?

I believe it's just started, i just bought the car a week ago but never noticed it knocking before, the car runs fine, it only knocks for the first minute when it's started then quickly goes away and runs smooth the car has 112k and the low engine oil light is on but the oil is'nt low
Pontiac Mechanic: FIXITMAN, Mater Technician replied 8 years ago
Okay. THis is actually very common on this engine. It is typically piston slap and is considered to be normal. As long as the noise only last for a short time then you will be fine. I would be sure to use a good delco oil filter and the right oil weight when doing oil changes as this will affect it also.

Do you know why the oil low engine oil light is on? its only on when the car knocks, asoon as the knocking stops i can turn the car off then turn it back on and the light is gone
Pontiac Mechanic: FIXITMAN, Mater Technician replied 8 years ago
If the oil level is fine then the low oil light should not be on. It may be a sensor issue. If the oil pressure light is on then you may have a problem with the oil pump. I would first do an oil change with the right parts to see if anything changes.

the oil pressure takes awhile to build up, and when it does it never goes past about 175 is this normal?
Pontiac Mechanic: FIXITMAN, Mater Technician replied 8 years ago
The oil pressure does not get past 175? Isn't this the temperature gauge?

oh yeah im an idiot, its temp its good,
Pontiac Mechanic: FIXITMAN, Mater Technician replied 8 years ago
Okay. If the oil light is on or if the oil pressure does not build up right away then the oil pump may be getting weak.
