Wooo MPGs

When I first bought my 2000 BMW 323i two years ago, I solved the main problem the previous owner couldn't fix by replacing crankshaft position sensor. I put in a Mayle (made-in-Germany, but non-genuine BMW) brand sensor I pulled off another car for $20, and the ignition misfires went away.

I lasted me until now. The sensor started acting up again, and my check engine light came on. Although there were no misfires, I did notice my gas milage slowly decreasing, sometimes averaging as little as 22 MPG even with mostly highway driving. People online reported that genuine BMW sensors tend to last longer, so I decided this time to spend the $120 on a new OEM sensor.

Right away I noticed my car running stronger. After my first commute to work, the fuel efficiency reading on my dash went up to 31.3 MPG! The highest I've ever got on this car was 26, and that was on long stretches of open freeway between LA and SF. Getting around 30 MPG in a 12-year-old BMW during a daily commute makes me happy.

Mechanix gloves

These are my favorite. They fit very well, and allow you to pick up the smallest little objects. I like the FastFit version with elastic cuffs that's easy to get on and off. They make a lot of different types.

318ti cylinder head installation

This is the second part of my head gasket fix. I've been putting the engine back together a little bit at a time over the past several weekends. I meticulously cleaned all the parts and worked slowly to make sure I didn't forget to reattach anything. I definitely didn't want to have to take everything apart again.

All the new seals seem to be holding up well. No more exhaust leaking into the coolant. I have yet to figure out why the engine still idles rough. But at least the major fix is done.
