There is a typical engine ticking sound when oil is not at max level. I still have it even with rockers and lifters replaced. Half way between min and max has a ticking sound noticeable standing in side of engine bay. Adding oil will muffle the sound. This is the way this engine sounds. Posting a YouTube video would help a lot getting more accurate responses.
BTW, motor mounts issues are changing slightly when transmission is in drive or reverse, lift the brake and slightly accelerate when keeping the door open, you should be able to hear a noise difference if mounts are shot.
So you are saying if oil pressure goes up the ticking sound goes away?
I'm only talking at idle, when oil pressure is the same as long as there is enough oil in the sump for the oil pump, so for me, if I'm in between min an max half way on dipstick, I have some slight ticking, if I add more oil to the max, the ticking is almost gone. I am not sure exactly why it does that, since it doesn't make sense. If I max the oil on dipstick then it will drip it all over through the provent return hose, till it stabilizes at 1/2 dipstick level. I'm not concerned about the slight ticking bc oil analysis are good, so there is no excessive wear.
When I rev the engine, I don't notice any ticking sound difference between max level and 1/2 level.
I also noticed that engine is a bit quieter with 5w40, be it Rotella t6 or mobil tdt, versus having the Mobil 0W-40. This makes a bit of sense since the diesel oil is a bit thicker even at warm than the 0W-40.
