Got an unexpected 2wk time-off from work, so I jump straight into valve adjustment on my 2009 ABS black, @ 15k miles.
In general most intakes valves were at or below the low spec (#1 pair being ~0.003mils). Exhaust valves were 0.008~0.009 mils. I took me two tries to get shims right (dealers don't have all sizes in stock). After I buttoned it together, it was pleasure to hear the engine running.
Completed the following
- valve adjust
- changed spark plugs (wasn't really needed)
- removed flies & added PCV
- added hoses for TB #1 & #2 (#3 and #4 already go to CA box)
- K&N air filter change
- changed coolant, oil, rear drive oil.
For removing flies, I ran the engine little bit to warm it up. So all screws were hot and came off easily using JIS #2 screwdriver.
My recommendations for others planning on doing valves:
- If first time, plan for 4 full days (and tell family to forget you).
- Finding right shims locally could take time and extend the work duration (btw I paid $4 per shim)
- Get Fred's videos and watch it while doing the work.
- Plan for space - it took a day to get tons of stuff out of the way. Organize them in order.
- it’s hard to imagine there will be room over the engine to do all the work but actually there is a lot.
- Anytime moving small pieces (like screws, shims) over the engine, hold it as tight as possible; don't drop it.
- Get a strong magnet to lift shim bucket (magnet also holds the shim together too; hence strong)
- if something rotates, think twice before rotating it
- Whole thing is not difficult but lots of steps. (plan for milestones and take a break after each milestone.)
- Expect to throw lots of dirty words, gets your hands bloody but then reach calmness & content when done
I respect this engine a lot now.
I will do it again in 15k miles - it's kind of fund
Since I removed the flies, where do I find a PCV map for "no flies + stock muffler + KN filter"?
Last, if anybody in the bay area wants to do this, I can offer help w/ tools, extra hand, and morale support
