Need some help. I did a valve adjust on the gf’s 2007 Accord EX last night. Mileage is 102k.
Prior to the adjustment, this engine was very very quiet. But it seemed a bit lacking in power compared to the other 2.4s I’ve driven. Vibration at idle was fine, maybe a bit on the higher side.
This is my first time adjusting valves.
When I did the inspection, all of the intake valves took the 0.008 gauge with a light amount of drag. I also tried the 0.009 gauge – more drag obviously. Based on what I could tell, the intake valves were probably in-spec but a little on the loose side. I’m not too sure of my capabilities so I decided to leave them alone. The spec for the intake valves is 0.008 to 0.010”.
On the other hand, the exhaust valves were all too tight. I loosened the screw about 30 deg on average, maybe 45 deg on one or two. The 0.012 gauge slides in/out with a light amount of drag. 0.013 will still fit in, but with a moderate amount of drag but would sort of “get caught” and the feel gauge would just get stuck. The spec for the exhaust valves is 0.011 to 0.013”.
I put it all back together, and here’s what I’m noticing:
- engine is noticeably more responsive
- but engine is much noisier.
- vibration at idle seems a bit less in gear, but more in Park/Neutral.
Not sure if I did it right. What do you guys think?
Thanks.
