Mine almost make the same noise.My Engine is JDM 1989 Integra Xsi B16A with around 70K miles on it.I thought it was the valve clearance also.It was off a little on valve number 2 & 3. But after I adjusted according to the manufacture spec and the ticking noise is still there. Is it this engine should make that kind of noise?Is it normal? Thanks.

 

im not worried about it anymore.....i got together with some of my racing buddies and the b20 b18b b18c1 all sound the same ......im just a over protective owner of my new born baby (b16a2) but thank for you guys helping me out
