I haven't heard any knocking so far finally. I changed the oil filter to the original one and it got rid of it. But another problem I got was a small oil leak. After I changed the o ring it seemed to. Have stopped but I haven't checked it lately. What other thing could cause the leak.

Check your crush ring & o-ring to ensure that there is one on there & in place, but not 2 on there by accident. Then make sure the filter & drain plug are secure. 9 times out of 10, an oil leak occurs after an oil change due to an o-ring or crush ring issue.

I changed both and haven't had the chance to check them. I might still have an oil leak...hopefully not.

Did you happen to notice the level of the engine oil PRIOR to draining and changing? Also, were there any metallic flakes on the oil drain plug? That would also be an indication that a bearing race failed or that some major internals are in need of attention.

What's a mystery is that the problem is intermittant. Do you hear knocking upon gradual acceleration or under a load with a mild acceleration?

The reason I ask these things is to isolate the nature and location of the "knocking." I hope that no one else is experiencing lubrication system problems IF that is what is happening to renesis.
