OK, lets put this one to Bed.
(Breaking in The new engine)
Start it, Run engine for 20 min at steady 2500 rpm, Let it completely cool down, change the oil,
Recheck (valve adjustment, timing, and idle/mixture).
Then the Most important part, Drive or use it just as you would once its broke in.
If everything was done correctly You have nothing to worry about. This is not 1950-60 tech hear
ring seating problems only happen now with cheap parts or poor machining!
? What do they do with the millions of engines produced for every vehicle on the road?
Easy, Read the above description again. Except, They don't change the oil.
I have worked on cars and trucks professionally for 20+ years. You know how many cylinders I have seen with ring seating issues. Maybe a handfull if that!
