Compression test results
It's amazing to me how many chores we have to do to gain access to our Boxsters. Anyway, here are the numbers for the compression test:
Cyl 1 - 133 psi
Cyl 2 - 140
Cyl 3 - 133
Cyl 4 - 121
Cyl 5 - 126
Cyl 6 - 122
WOT, performed at room temp
Now I can see the second bank is lower, but it should not just flood. The car has 96000 miles, had 7 owners, and they probably drove the piss out of it. I'm still suspect of the Bosch Platinum +4 spark plugs. They've been in since troubleshooting began and have been flooded several times. I have a new set of Bosch 7402s that look like OEM. I'm tempted to try them.
