I have just done a valve adjustment on my 99' Accord LX. it has a 2.3L VTEC with a 5-speed. The valves are still quite noisy and i was wondering if there was a way to stop the noise. I did the adjustment tolerance that was stated in my Hanes manual and i was wondering if i should just go with a smaller tolerance (bring the rocker closer to the valve) because of the mileage on the motor i guess that it has worn the rockers and made the factory recommended adjustments useless. I have 132,000 miles on the motor.

 

I have a 98 LX 5spd with 127000 and my valves were loud as a **** before and just as loud after I adjusted them. I think it's just a noisy motor. Now I have a noise that sounds like I have a loud super charger whine. I have only had time to make sure it's not an alternator bearing going out. So if anyone has had this problem let me know.

 

DO NOT MAKE THE VALVES TO TIGHT!!!! they will burn up. better that they are alittle loose then too tight. just like the manual says...there should be a little drag when you slide the gapper through there. some motors just have play in the valve train. if you switch to a thicker oil a lot of times it will quiet it down. i personally recommend lucas heavy duty oil stabilizer but thats kind of expensive. i know some mechanics that recommend using a straight weight oil in higher mileage motors.

 

right now im using Mobil 1 5w-30 because of the cold weather were i live so should i switch to Mobil 1 10w30 to quiet them down now that it is warmer out.

 

That kind of an oil change won't quiet the valvetrain. A switch to German Castrol 0W30 might quiet things down as it is close to being a 40 weight. It's not an easy oil to find however and you may see a slight MPG drop. If it's running well and not using oil stick with the M1, if the noise is making you crazy sometimes a switch to 5W30 dino oil will quiet it down.

 

What was the gab you set youre valves too? I would like to set my the clearance on my valves but I don't know the correct space.

its different for different motors
