hey any one with the same probelm as me? I change my oil 2 days ago for a reason that my car started knocking.. yeah fuck... after changing it the knocking went away. About an hour later as it cooled down I turned it on again and it knocked again.. less this time. I called hyundai dealership and asked them. They told me what oil weight was I putting in. I told them I was putting 10w30. The guy gave me a big NO. He said that the gc is specialized only for 5w20. After paying 75 dollars for the oil, the guy told me to change it again asap to avoid any further damage. Yeah again I paid 75 dollars, the next day. Changed it yesterday AGAIN, the knocking went away again. Today I turned it on and no knocking, great news. About 30 min later I turned it on again to go pick up some stuff and the engine knocked for about 2 secs, FUCK! ANY IDEAS ANYONE PLEASE PM ME. I'M TIRED OF THIS CRAP. THANKS

It sounds serious. The biggest problem you have is that you called the dealer and basically told them you used the wrong oil. So if it is a bearing that went bad, they are going to tell you too bad, you screwed up. You should have no knocking so this is a problem. My guess is a rod bearing. Not sure why it comes and goes though. Wait for others to chime in. It would really suck if your motor went. It sucks even worse it was doing this before the oil change. But like I said, unless you kept it anonymous, they are going to be waiting for the denials. Did you have a good level of oil before the change?

Unhappy

Yeah well my dealer didn't say anything about voiding warranty prolly cuz I knida know the guy, but I got this problem before my oil changes. When I changed my oil the first, the knocking was the reason I did it. The oil wasn't even burnt much, so that is why I changed it. And now I have another problem, the rubber ring around the oil filter canister was replaced with the ring that comes in with the stp filter, and I'm guessing that it is a smaller width because now I have a very very slow leak of oil leaking out around the anister. Do you know if the oem ring is bigger than any other? I was going to go to dealer today to buy oem ring but they close sundays.

It's pretty easy to put the ORing on the wrong groove on the canister so maybe if you did that, put it on the wrong groove, you could have a leak. Something to consider. But there's no way that using 10W30 will wreck bearing and whomever is telling you that needs to stop talking right away. Worst, the WORST case of using a heavier oil would be gas mileage going down but it's not going to hurt the engine. Not one bit.

+1.......10w30 weight oil will not cause the knocking you are speaking of renesis & like Austin said; at worst will drop your fuel mileage due the higher weight/viscosity of the oil.

renesis, since the knocking occured shortly after the oil change, I would guess that the 2 are related & I'm very doubtful you spun a bearing etc. I agree with Austin that the issue lies with an o-ring etc. I would check my filter for no o-ring, 2 o-rings, improper seated o-ring & so on. Also check the drain plug for no crush ring, 2 crush rings, original crush ring, etc. More than likely your oil filter is not seated properly.

AS I recall there's a TSB for engine knock for using a non-Hyundai oil filter cartridge.

Yes, I remember now....there is a TSB out regarding aftermarket engine oil filters causing knock. Thanks Austin!

If you are using an aftermarket filter that may be it!

I used a Wix on my 3.8 and didn't have an issue, the last two were Hyundai though.

I've only ran into a couple filters that caused this & its been a while since the last one, thus why I forgot about it.
