I've got a 2006 CRV front wheel drive with 120,000 miles. In the past I've had a little problem with low gas mileage (22-24 mpg) but now it's back up to 27+ mpg....I chalk that up to poor fuel mixtures. In the last 5,000 miles it has developed a ticking valve. It is only for the first few minutes when I start up, then I don't hear it anymore. I've had a honda-certified mechanic tell me that he can do a valve adjustment that will take care of that valve tick but I've had another mechanic tell me that a valve adjustment won't help that situation at all. I've had a motor aficionado tell me that as long as the tick is going away after a few minutes and the performance is good that it's nothing to worry about.
I have done all the prescribed maintainence and change the oil about every 4500 miles.
I need some input on the seriousness of this situation and what I should do?
