As the car gets older, and the warranty comes to an end, are there any drivers out there that do NOT have had the metallic ticking noise from the engine? I had it a couple times during the winter period last year, the dealer did the bleed procedure and so far it did not return. I read up on the Metallic ticking noise sticky as soon as there is a new posting, and read most of the previous 37 pages. I am worried about the future when the car is out of warranty and the ticking returns. I own the car and am building a LTR with my vehicle, so it needs to last w/o ridiculous $8k repairs that may be a designer error/material tolerance and I cannot do anything about. I know a lot of people face this issue by reading the sticky; I do not know how big is the other group who has no issues??? Also, for those who had the cylinder head replaced, did it fix the problem?
