This week I hit 3500 miles on the build. Time for the first oil change following the break-in period. I ran the oil through a strainer - no metal particles. Good. I decided to pull the valve cover just to check things over, and found THIS:
On the exhaust cam, cylinders 2 & 3, the vtec lobes are wearing BAAAAD. The cam is literally crumbling. You can see a little shard in the picture. Good thing my oil filer is picking up this shit. This is unacceptable for a street driven car with 3500 miles. I checked the lash and its still right on. It's like whatever heat treating they did to harden the camshaft didn't quite get to the center of the cam.
The setup is skunk2 stage 2 tuner series cams, skunk2 valve springs. fresh lma's. Hell, the wiper pads contacting the bad lobes looks like new. Usually the wear is the other way around - over a much longer time period. I had the rev limiter set at 8k up till 2 weeks ago when I raised it to 9200. I paid over $650 for these brand new
Any of you guys experienced something like this?
