​​​​​So let's start with the issue. Now that it's all gone bad, I'm thinking back to when I got the car two years ago .I brought it home and noticed a bit of a grinding sort of noise, seemed to be coming from in around the left of the engine. I took it in and had it inspected, and was told they weren't sure what it was, but it was not anything that I should be worried about. That always bothered me, but I went with it. Fast forward to last fall (around 110 000km). I drove to a restaurant, far enough away for it to get up to temp, and had breakfast. When I came back out, it threw P0302 , and was obviously running on 3 cylinders. I turned it off immediately, and tried it again. It started up with no issues and all was well. I brushed it off thinking it was bad gas, and went home. Then it happened again, so I parked it and started researching.

I started by replacing the spark plugs, which hadn't been done since the supercharger pulley was done. I pulled the plugs, and none of them looked too bad. I did notice that my cylinder 2 wire was corroded, and the little nipple actually broke off and stuck to the plug when I tried to remove it. So I went out and replaced my pretty and expensive kingsborne wires with some Bosch ones. With fresh plugs and fresh wires, it still would run on 3, and still only on cold start. I tried running injector cleaners and the usual cocktail, no improvement. Then came winter, so I parked her and waited.

That brings me to last week. I got a fresh coil pack (OEM), and put it on. It had no impact. I went back to the internet and found something about dirty intake valves, and tried some seafoam. It helped a bit, and it would only misfire every third cold start or so. It seemed to get better over time, so I was planning on doing another round of seafoam, thinking it would clear it right up.

And then it got worse. Last night after work, there was a tapping/ticking noise. I figured I hadn't checked the oil in a while, so I went to and realized I had forgotten which hole it was supposed to fill to. I know when I got the new dipstick, I read to fill it to the third hole, right under the little slope. That was my first mistake. Apparently for the past two years, I've been running it low on oil. Hoping for the best, I filled it right up. It drove fine, and I thought I had fixed it. The next time I turned it on it sounded even worse and louder. So now she is parked, and waiting for me to figure out what the next step is.

So, after that novel, here are my questions:
