I just had my head gasket replaced on my 05 civic...
Driving city speeds felt fine, but I did notice a little bit of rattling, which I thought was just a new sound she would make due to the engine repair.
I hit the highway, and as soon as I start accellerating I get a Check Engine Light. I get home, and run the codes and it is a P2646 'A' Rocker Arm Actuator System Performance / Stuck Off Bank 1.
What the P2646 code means
P2646 is an OBD-II generic code for the engine control module (ECM) >detecting the 'A' rocker arm actuator control circuit for bank 1 has a >performance problem or is stuck in the off position.
So, this morning I check the Oil and there is NOTHING on the dipstick...I check underneath the car for leaks and find none.
I see on my oil cap it says 5W20...and the receipt from my mechanic says they used 10W30 oil...
Did they use the wrong oil causing this to happen??? Would my dipstick really be running clear after 30 minutes of driving with the wrong oil??? Or did they forget to fill it up at all...
EDIT:He overfilled it!...I guess I was too focused on the dots to realize that the shiny new oil was covering the entire dipstick...Just got it drained and refilled to correct level by my mechanic...all good for now. Thanks for the help guys
