First, thanks to everyone who has posted here. I'm a newb, from the subaru world, and have been thinking of upgrading to a used e90. All other maintenance issues aside, this engine ticking issue seems like a reason to not purchase a used e90 (unless its CPO).
My reading has found:
a) Some say using thicker engine oil works. Claiming BMW is using thinner oil, to increase fuel economy.

b) Some have changed to thicker oil, with no improvement.

c) The engine ticking does cause physical damage to the camshaft lobes, and I assume will limit the life of the engine (i.e., I should not expect a used e90 with high mileage (70,000+) to last much longer). Quite a change from previous generations, like the e46.

d) Some have exprienced improvement after replacing the "Hydraulic Valve Pushrods".

e) Some have replaced the "lifters", only to have the ticking return.

f) Guess I need to be ready to drop $7500 to get a new head with the new 'check valve' installed, that will keep the oil where it needs to be.

Question: Can you help me confirm, I should look into an e46, G37x, IS250 AWD, or just stay with my WRX??
...I'm not trolling, just looking to confirm the e90 is not the right car for someone who cannot afford to lease, and instead buys cars used with 50,000+ miles, and does his own maintenance.
Thanks, and happy holidays.
