This is a great forum. I have an ATK rebuilt 3VZ-E with 10K miles. Not happy with it but warranty is up. Rear main seal leaks and lifters on the left bank are so noisy I think it's setting off the 52 code for the knock sensor. Possible? Sometimes the lifter noise goes away and I don't get a "check engine" light. Is it possible?

I'm going to flush and change the oil and see if my noise (and light) go away. Thanks.
