I’ve inspected my engine bay and there seems to be no oil leaks except the one near the valve cover which is very very small. I will do the compression and leak down test for sure tho.
I am wondering whether or not to change my timing chain if I am doing the valve cover. There is no knocking or sounds from it, but isn’t it about time for it?
