Can I run several tanks in a row for example after the 3rd tank to speed up the break in proccess or should the engine cool down after each tank?
Thanks in advance.
I always let it cool down in between the first tanks (first 7-8). It helps the materials achieve their proper fit.
Remember your engine will last as long as the time you dedicate it on break-in.
Quote from Ron Paris:
Heat cycling stabilizes the metal and allows mating parts to fit better against each other. Keeping the piston out of the upper portion of the cylinder (which is smaller in diameter than the lower portion in order to create a better seal during combustion) will allow the cylinder to properly contract as it cools—without interference from the piston.
