I started my 340 up this spring and noticed a **** load of blow by. I finally got around to doing some tests on it today. Compression is all over the map. There is light blue smoke coming out of the tail pipes. And you can see the amount of blow by in the video. The plug check showed all cylinders a little rich except #6 which showed a little oil fouling. The car still pulls like a freight train. Keep in mind this is 340 with a roots 6-71 blower on top. I am pretty sure a complete refresh is in order. Rings, bearings and a hone job for sure.
Compression test results:
1------128
2------121
3------120
4------118
5------122
6------95
7------112
8------168
What do you think?
