This is why you can't trust anyone to work on your car.
I guess I never thought about the chisel and hammer. Oh I did try vice grips and a small pipe wrench. But the pan is aluminum so it's probably better I didn't hit it with a chisel for fear of cracking it or something. This oil.plug problem was on my 2007 dodge magnum. I've got another story, it's about a fuel pump though. When I was about 18 I had an 84 Ford ranger that was acting up, seemed like a sticking fuel pump. I bought a pump for it and left it in the cab. Sure enough it was. So I parked it in my dad's yard and put the battery from the ranger in the other ranger I had. 86 4x4. Anyway, I told my dad I would be back for it in a few weeks. (I didn't really want to mess with it at the time. I was busy working 12 hour days.) So while it was at his house he thought he would surprise me by getting it fixed. So without my knowledge my dad calls our local mechanic and gets it towed to his shop. So I finally get to my dad's house and I ask where is my truck, and he tells me he had it towed to he fixed. So we drive to the shop and the truck is sitting in the lot. The mechanic hands me a bill of like $130 bucks and so I ask."did you replace the fuel pump?" And he says, "no, it didn't need one." So I look at my bill, and it has a new battery on it and new belts. I was pissed, it didn't need a God Damn battery and belts! So I test drive the truck and I didn't even make it around the block because of fuel starvation. I walk back more than Pissed off. I say "go get my truck and replace the fuel pump like I said to begin with! I'll be back in a few days!" So I come back in a few days and now my bill has gone up to about $250. The first thing I ask is, "did you replace the fuel pump?" He says, "yes, I had to do some other work too." (This pickup had dual tanks on it) so I said" like what?" He goes on to say he had to disconnect the rear tank and fix the wiring for the tank switch. So I get under the truck and the fuel pump was replaced but everything is all messed up and fuel lines are cut open and wires are hanging all cut to shreds! I said" the switch worked fine I use it all the time!! All I needed was a new fuel pump!" He started to say something and I talked over him." Here is $130 for the battery and the belts. Give me my keys." So he handed my keys and I drove off. The truck ran great after the new pump. I've never ever taken anything to anyone again. I've never heard a single word about the rest of that bill from my dad or that guy. Grrrr! It pisses me off just thinking about it.
