The ticking was probably your hydraulic lifters. Pretty odd, considering a lower weight oil flows better and generally
stops lifter noise in other cars. I think it had a lot more to do with your oil pressure, then, in this case. I wouldn't consider running anything less than 10W40 in the VG30 anyway. That's what I ran in mine in the winter, and 15W40 in the summer. Mine was turbo, also.
