Is This an Indicator of Detonation?
Got the driverside head off tonight, I don't think any coolant got into the bore when I pulled the head off. Cylinders 1 and 3 had some build up on the tops of the piston compared to the others that had an even amount of carbon on the pistons.
There is less than 40 miles of actual driving on the motor. I broke in the cam bringing the RPM up to 2500 for 20 minutes and varying the RPM during those 20 min a few times. Cam looks fine.
I don't think oil is getting by the guides. Intake runners are clean and I don't see any oil on the stems in the port. I have an oil separator on the PCV. There was a little oil on there.
Could the Rings not be broken in yet? They were Childs & Albert Moly coated 1/16" top ring, 1/16" Ductile iron 2nd ring and a 3/16" Standard tension oil ring. I don't remember seeing any silver smoke out the exhaust.
