Can't believe most people on here never heard of lifter ticks before.

Car is at 180+ thousand miles, and the noise started happening after an oil change with some dyno noise. This is what happens if you don't use correct viscosity oil in high-mileage engines.

Just change the oil with the most viscous LL-01 synthetic to help with the noise next time around. It may still be there, but I wouldn't try and open up the engine just because of this.

Edit: Lifter noise is very common in e36 and e34 circles. The cure is what I said above.
