I just picked my car up for what will likely be my LAST warranty service .
I'm at 47K miles.
I'd complained about valvetrain racket once before and it was noted.
This time....They replaced all head componets,cams,lifters etc. Including all seals,bearings etc. at no charge.
They said they found scoring on the cams.
I even managed a new BMW/Exide battery...about 2" bigger. My OEM one had been down a few times and had to be jumped....they said after testing it was defective....
They also did my differential seals at 3 points.
Also front bushings,wiper blades,cabin filter,washer fluid and oil/filter.
They wouldn't do my brakes/rotors.....I was still at 5mm and 9mm. They require less at I believe its 3mm before they will do that.
I'll report back here again after some break-in time to see what the lifters sound like with some cycle time.
Cheers,Vinny
