Today’s adventure with the e46. Went to put fuel into it, as you do... do you think I could release the gas cap? No f#*king way! It was ‘in’, ratcheting to clockwise. But could not get it to budge a anticlockwise. Even using two hands and a wide grip (as you do). Gave up and drove home.
Later this afternoon, I gathered up a rag, my trick Knipex Cobra sliding jaw multigrips, penetrating oil, screwdrivers, and parts.
I sprayed some penetrating oil around the gas cap, and left it to soak. It was still stuck.
1. Replaced the hood struts. They were getting a bit dubious on cold days. Re-seated some of the seals under the hood.
2. Went to check the state of the fuel cap. It came open easily! Inspecting the seal, it’s compressed, hardened, and cracked. Time for a new gas cap, or at least a sealif it’s available separately. I cleaned around the flange of the fuel filler, and cleaned the cap sealing surfaces thoroughly.
here’s a pic for reference
A world-weary e46 fuel cap, this afternoon.
