I don't recommend rotating the engine by the camshaft as is done in this video. The circular plastic cover that has to be removed to do so gets brittle from heat and the tabs can snap off easily and fall into the engine. It could also put unnecessary stresses on valvetrain and timing components. It's best to simply use a 19mm wrench to rotate the crankshaft, as described in the maintenance manual. It's easily accessible from behind the engine. The engine will also be much easier to turn if you remove the spark plugs. Just make sure to torque them correctly when re-installing them.
Man I wish I looked at this before watching the video because now I have two plastic tabs stuck in the damn engine. I sure hope I don't mess something up big time now.
I’ve seen people regain a huge amount of compression after adjusting there valves. I’ve been procrastinating on adjusting my valves thinking it would be cool to do a before and after compression test to see what happens just incase mine are way off.
I was able to adjust the valves on my 2000 Insight thanks to this video. At 235 K, I found that about 75% of the clearance needed to be adjusted with most being too tight. Thanks for the help!
Yes, they'll typically tighten instead of wearing as these hardened parts won't wear much. Instead, the valve faces and/or seats wear and the valves "recede" into the head, closing this gap.
Thank you so much for this video. I've been noticing my valves are playing the sound of their people recently on startup at 138k miles. I noticed the interval is at 105k miles so I'm a little behind. I've done valves on a boxer engine motorcycle before but not on a 3 cylinder like this. Pretty straightforward and practically identical in concept.
Coming up on this with my 100k maintenance for the gen 2 insight. This is very helpful but I'm not sure if I want to tackle this one myself just yet. Lots of other maintenance to do.
People please don't remove the circular plastic cover, it will likely break and then you have a potential leak. Simply get a 19mm socket and rotate the cams via the nut holding the crank pulley on which is directly below the engine, can't miss it.
Why is everyone aiming for the lower end of the spec when the valve lash tightens over time with the ware of the seats? To me it would make more sense to go to the higher end of the spec to increase the time interval before the next adjustment. Am I wrong?
Hi, I'm aware of what the maintenance interval calls for, I was just curious as to how many miles were on your engine when you did the adjustment? Mine has 250,000 miles and as far as I know probably needs a valve adjustment.
Thanks. Much appreciated. I guess I’ve always been apprehensive of doing this. I have done things a lot more challenging and yet...this is so much easier than meets the eye.

Thank you so much for making this vid. So helpful

We need more people like you ✊ good descriptions
Thank you for this review this helped me SO MUCH on my 2002 insight
For a 2001 your engine looks great

Thank you for the video!
Great video!
Very helpful video but +1 on turning the engine via the crank

Before and after sound similar except for the idle speed. Maybe it was more audible in person.

I did mine at around 180k miles, no idea when it was done last or if it was ever done

Me too 252k. Great car
@@JRobling I'm now at 180,000 and about to see if someone in town sells feeler gauges, mine has a very loud tick and I've been putting it off.
