Running in a rebuilt engine.
Hi everyone,
I have done the usual search and google has come up with some very conflicting information.
I am just about to put new big end bearings and full set of piston rings into my 2.0 blacktop. What I would like to know is how to run in the engine
correctly. So, how do you guys do it, and if possible a reason for the method you use. I understand that there seems to be a bit of a grey area as to
exactly the right way, so looking for methods and reasons please.
P.S Lets not get into a slagging match about who is right and wrong, just a discussion on methods and reasons.
Thanks guys.
Andy

From what I have read, use cheap oil or mineral oil to run it in. Varying load and engine speed AKA just drive around but don't cruise for long
periods of time. Don't be afraid to go full throttle high RPM after a little while. I believe that the rings need higher cylinder pressures to
force them against the cylinder walls for good sealing.
However after I build my turbo bike engine, I fired it up to make sure it was working, then trailered it straight to the dyno for full power runs and
have beat the snot out of it ever since.

Have you changed the cam & followers? If so, everything changes...

Look at the bottom of the page for running-in instructions. I really impressed the neighbours when I did that for 20 - 30 minutes!

So, no, you really don't need to baby it after making sure everything looks good!
