The following steps were performed in order to obtain these measurments in ALL tests.
- Remove fuel pump fuse
- Unplug harness on Power Transistor going to the Coils
- Remove all the coils and spark plugs
- Depress clutch and accelerator fully
- Let engine crank until compression stabilizes
- Record pressure. This is the DRY measurment
- Dump about a capful of 5W-30 motor oil in the spark plug hole
- Wait about a minute for the oil to spread out
- Repeat steps 4-5
- Record pressure. This is the WET measurement
- Repeat steps 4-10 for each cylinder

Things that have changed since the last test:
- Used a BRAND NEW Snap-On compression tester (thanks Jason)
- Changed the oil and switched to 10W-40 (was running 5W-30 previously)
- Ran a can of STP Engine Flush and Prestone Coolant Flush through
- Installed a GREX Oil Filter Relocation Kit
- Installed a Cusco Oil Catch Can
