(B) Time for some head work

The Beemer has been acting up the last week. I had three things going on: low on coolant in the morning, white smoke at start up, and sometime it wouldn't turn over, it would just sort of "clunk" when I tried to start it. I ran a compression test and it came out at 205, 205, 205, 300(!), 205, 135(!). So I've got 2 bad cylinders. Looks like I'll be doing a head gasket at the least and a head replace/repair at the most. Parts are about $400-$500. That beats paying a shop $2500-$3000 to do the work. I know this, because I had head work done about year and a half or two years ago. I guess the oil change and Seafoam knocked something loose in the car.
