Hmmm, well if slightly over filling it improved it maybe it IS bottom end related... i honestly can't make a call on it. Mine has had the same tick for years now and no problems, leading me to think it's just valve lash, but the fact that your tick got better when the oil was overfilled should indicate that it's bottom end related.
I feel the same, don't know so I just drive but I do let her warm up in the morning when is colder :driving:
still sounds the same, over filling it helped make the sound a little bit more quiet once the engine is warm.
The tick sound has a consistant noise level, it doesn't get louder, or quieter, it gets faster or slower based on the RPMs.
Once the engine warms up, I hear it and it basically sounds like a sewing machine.
I check the oil today, i check it on wednesday, check your oil wednesday and it is still full. I made the mistake of overfilling it, I added 1/2 of 1qrt and it made it go up to the H mark
I took a picture today and this is what it looks like. the oil is 2,500 miles Old, I still have 2,000 more miles to go before is changed. and even after 5,000 miles it doesn't look completely dark, it has like a darker brown color.....
..............but here it is, sorry the quality picture sucks, [cheap phone]
both holes were full, but I change the oil a lot so she has good clean oil all the time. if the rodbearings fail, it won't be because she was low on oil or I didn't change the oil. i check the oil all the time, at least once a week. and that's pretty much all I do.
When I drove her to Florida 1,800 miles on one weekend, (that's why the engine got so dirty...lol) I checked the oil and coolant every time I filled it up. the oil change place told me I should be able to make it to Florida there and back twice...I said okay I will drive the Versa and not get a rental. i got road side assistance just in case thru my car insurance.
anyway...tick still there, oil is good, no smoke, no problems, just tick tick tick when she's cold and it takes about 30 minutes of driving for the tick to be reduced to 50%
