Haha! Nice one!

By the way, off topic, done any more bonnet cutting activities lately?!

 

I did mine with the smaller gaps and it seemed to make the valve noise worse. So I went back and did again with the standard gaps, and it didn't make any difference - was still louder than before. Oh well.

It's easy enough, if a bit fiddly. Obviously you need feeler gauges, and an appropriate torque wrench (i.e. a low range one, not a doing up suspension bolts one).

 

I was considering doing some more tomorrow but may have to spend some time with the family instead.

 

Id love to take the trip up to tegiwa for the adjustments but it's just too far for me. Im in south wales.

 

I don't do anyone's car to those settings, bar an experiment with mine.

8 and 10 is perfect, but remember that the tolerance is 2-3 thou so expect someone to whizz around check them with the upper tolerance and not adjust them to minimum spec.

I have done cars that have had this done at Honda and they have been miles out.

As for torque, I wouldn't trust the 21lbs/ft at all!

 

Sorry UN, I don't understand your post. Are you saying you tried 7/9 as an experiment? What did you find as a result?

And 21lbs/ft? What are you referring to there?

 

You really don't need a torque wrench on the locknuts is what Nexus is referring to I believe. A decent sized 3/8" ratchet and a gentlemans nip up is the way to go.

 

I improvised the valve adjustment tool with a 10mm box spanner and a screwdriver but IMO it really wasn't necessary (especially not necessary to fork out the £30-odd for the proper tool that was the cheapest I could find) I used the S2K_Valve.pdf only as it was easily printable to take out to the car with me for the torque settings

 

That was my approach. I've done enough of them over the years to know what I feel comfortable with.

I have an open socket set that I can get a screwdriver through that I use. It's very handy.


And from the drive to work this morning with 7/9 clearances, it really does feel like I have more pull and response from 2.5krpm to vtec point. The changeover into vtec is less of a kick now but it certainly feels like it makes the car more drivable. This may well all be placebo effect however.

Pre-change, all my clearances were within tolerance but now they're all 0.007 and 0.009.

 

To add though, I don't know what the long term effects of 7/9 are so I'm not recommending them by any means..
