Valve clearance and metal particles
Hi there, guys I'm doing my valve clearance and when I opened the throttle bodies I could see the IN valves with some metal particles on the top. Is it bad? Any way to remove these? And then I checked the clearance and I was at 0.200 on all the IN valves. Does that make sense for you, I mean I am on the top of the range already, so has it damaged the valves seat?. Also, for the EX valves, I have 0.350 on 3 of them but I saw in this forum that a certain VIN has a clearance range up to 0.375. However I have 0.340 on the others so I must be out of range somewhere! You insight and help is much appreciated! See the pic attached!
