ADJUST THE VALVES

General Useful Information:
1-Make sure the engine is cold, less than 100 (DUH).
2-Ummmm.... it is not necessary to drain the oil, but schedule the adjustment during a oil change.
3-Use the next size up feeler to get an idea of too tight. Its better to be loose than tight.
4-Both valves will be closed when a cylinder is on its compression stroke.
5-If you don't know which cylinder is which, the spark plug wires have numbers on them. But, Brake side is #1 at front then #3 then #5. Shifter side, #2, #4, then #6 front to back.
6-use silicone in the 4 corners (90 degree) of each valve cover when re-assembling. (oil leaks)
7-careful! those big headed cover allens are fragile. Tighten to 12 N.m (9lbf.ft) [note, that ain't very tight at all].
8-Always turn the crank counter clockwise.
9-Put a turkey roasting (or some such) pan under the covers when you remove. They will have a little oil in them.
10-plain old generic clay kitty litter is excellent for "floor dry." Absorbs the oil right out of concrete and sweeps up for re-use.

GO FOR IT
1. Start by removing the cylinder head rear cam covers (4 allen screws).

2. Next remove both valve covers, 12 big head allen screws with black plugs.

3. Remove the timing mark cover located at the end of the crank on the front of the engine. It's round and has three allen screws.

4. Turning the engine counter clockwise, align the 1,2 timing mark with the indicator using a socket w/ratchet. Be sure the #1 cylinder is on the compression stroke. On the compression stroke, both valves will be closed on the cylinder and the springs will not be compressed.

5. After aligning on the 1,2 mark, check #1 intake clearance .006"and the exhaust clearence .009" (all cylinders are the same).

6. If things seem very wrong recheck the alignment mark/compression stroke or see that two of the feeler gauges didn't stick together :(

7. If you need to change anything loosen the lock nut while holding the adjusting screw with a larger flat screwdriver. With the nut slightly loose, turn the screw as necessary to reach alignment (slight drag on feeler gauge). Recheck the clearance after tightening the lock nut. Torque 23N.m (2.3kgf.m, 17 lbf.ft)

8. Now rotate the crank counter clockwise 120 degrees to the 3,4 timing mark.

9. So now the #4 cylinder should be TDC, check\align the #4 cylinder.

10. Next is the 5,6 mark with #5 coming TDC, check\align the #5 cylinder.

11. Next is the 1,2 mark with #2 coming TDC, check\align the #2 cylinder.

12. Next is the 3,4 mark with #3 coming TDC, check\align the #3 cylinder.

13. Next is the 5,6 mark with #6 coming TDC, check\align the #6 cylinder.

14. Lube the gaskets to reseal.
