TOP END BREAK IN

[Brad]

How long should it take for a new top end(pistons rings renicasaled cylinders) to seat the ring before switching back to synthetic oil

TOP END

Start it warm it up for 10 min. then cool down for 1/2 hour do this about three times,upping the time buy 5 min. Then for the first 100 miles varie your rpms,but not wide open,after the first 100mile short bursts till 250 then go at it!Hope this helps
