its the way ive broken in 2 engines, and 3 of my friends have followed those guidelines as well and have very reliable engines, if i do break the engine or it doesnt last more than 50k miles ill buy a new one and break it in like the manual says...
when i break in an engine i drain and check oil for metal shavings every 100-200 miles and refill with the same oil till 4k miles, i do this mainly to filter out as many shavings that do come out during break in that isnt caught by the oil filter
i want the rings to seal better and to keep compression as high as possible, i broke my current engine in like that, and its got 50k miles and i havnt lost compression or had any other problems, can you explain why my method is bad if it works?
maybe it wont work with all engines and thats what im trying to figure out, if it is a good/bad idea for this engine to be broken in hard and i will gladly fork over 6k for a new engine if my warranty doesnt cover it...

Based on all the anecdotal data there may be something to the break it in hard idea. However, until I see scientific data ill remain a skeptic and will follow the procedure that is recommended by companies that have built their entire reputation on reliability.
