when coming to a stop after driving on the freeway or 60+ mph for an extended time I keep getting a low oil pressure warning. The engine doesnt stutter or do anything odd other than the warning. If i turn the car off and let it sit for a minute then start it again the warning doesnt come back on. Even after spirited driving it wont come on, only after doing 60+ for a while then coming to a stop. anyone know what could be causing this and how to fix it?

specs: 2013 gsr 8,000miles
AMS DP, 3" testpipe, 3" catback , 4" depo intercooler, full hard pipes, K&N cone filter, grimmspeed 3 port

 

Stupid question, did you check your dipstick?

 

yeah my oil level is good and i just did an oil and filter change change yesterday

 

noone?

 

check oil pressure with a mechanical gauge. if oil pressure is ok, replace the oil pressure switch.

 

I had a similar issue on my 9. It was the pressure switch like the previous poster have said.

 

where is the pressure switch located?

 

It's underneath the intake manifold threaded into the block. There is a bracket that stabilizes the manifold that needs to come off and then it should come out pretty easily.

 

Get a mechanical gauge and verify the pressure. Its its in spec then replace the sensor. DO NOT drive the car with the oil pressure light on. I had a customer that did some of his own work and left a rag in the oil pan during a re-seal. It got sucked up into the oil pump pickup. The oil pressure light would come on randomly. He kept driving and ended up seizing and snapping a camshaft.

 

He forgot a rag in the oil pan, sealed it up, and ran it?! That must have been awfully embarrassing for him.

 

Yep. Clogged the oil pickup after a few miles. Destroyed the whole head.
