I recently bought a 2006 Hyundai Sonata 3.3 V6. Had another issue related to the rear wheel, which I fixed. Today, I changed the oil filter on the car (along with the oil). I have heard this engine noise before, but with the cover off it appears a little louder. It’s basically a ‘ticking’ sound.
The engine uses no oil, and has no other leaks. It has some noise on startup for maybe 1-2 seconds (like a loud lifter or something, but it goes away in less than 2 seconds, and at the same time the oil light goes out). I changed the filter today because I was told that a leaky gasket could result in the Filter not retaining oil between starts, causes some minor knock for a few seconds.
But anyway, this other ticking noise seems to be regular, regardless of condition. I have heard some people say that some engine noise is normal for this engine, but how about this?
