oil change = slight engine knock
I did an oil change and put in Quaker State 5w30, now I have a slight engine knock that speeds up under acceleration.
Also I cleaned the engine off with some degreaser. New plugs, new wires, new ignition coil, new distributor cap |
I don't know what year Accord you have, but my '00 uses 10w30 oil. What oil did you have it in before? Are we talking a knock or is it more like a lifter? Normally, if the noise increases with speed, it's a rod. I don't believe that you have that problem, because if it was it wouldn't be described as slight. When I saw the 5 weight, I was thinking that possibly the oil is too thin. Does the car idle smooth?

97 accord v6 automatic.. not sure what it had in it before, just bought it a month or 2 ago.. it does sound like a ticking/tapping
yes it idles great |
You probably need a valve adjustment.

Despite 5w-30 being the standard oil recommendation in North America - Texoma, TX in summer it so continuously hot that I'd consider more viscous oil in the undo-change. Example, yesterday I just drained and filled enough to make my oil 50% 10w-40 in my two Accords because of continuing 100+F forecast temps with the rest of the summer still ahead. I don't want an argument, I'm just saying what I did - so I practice what I preach! Oil brand. I had an unsettling experience with QS brand oil a long time ago and avoid it. |

What brand of oil do you use UhOh? |

What brand of oil do you use UhOh? I saw that after I mentioned it. I checked for the procedure to send to you, but found out they are not adjustable. My Accord is a '00 4 cylinder. I have been using Castrol GTX 10w30. As UhOh mentioned there were some problems with QS several years ago, but they have supposedly worked it out. I've been using Castrol for years, dino and synthetic, never any problems with noisy tappets. |

Listed in no particular order. I've also had bad results switching to "synthetic" and "high mileage" oil when the engine seals and gaskets are used to plain jane oil. One thing you could consider is calling the prior owner and asking him what kind of oil he used in the car. <Older cars with miles ... you don't want to experiment. Been there, done that.> |
What kind of filter did you get. Sometimes cheap filters in my 95 will make the valves tap. I switched to the most expensive filter I could find. K&N
