how long does it normally take to break in a motor with new pistons and rings, also new valvetrain, is it typical for it to burn excessive amounts of oil

 

i wanna know too

 

somebody know anything?????

 

im running fresh bottom end with 12:1 pistons, new crower valvetrain. i left vtec disconnected for bout a week. first day i drove it like a granny....giving it full throttle here and there.........rest of days i drove it normal never letting it see 6 grand......1 month later rings settled fine (no smoking) and it still runs oh so strong!!!!!

 

change oil at 10-20 miles and at 500 miles use good oil not synthetic until later after the 500 miles if you want to.
don't hammer it for 500miles i couldnt wait.
this is what i did and this is what my machinist told me when i got my motor done.
i used castrol GTX and a K&N filter.

 

how many miles before your rings seated and how much oil where you losing???

just curious becuase I am having ring seating problems. ie, second set of rings in 1300mi for me. I have 350mi now but the engine still smokes like a mother.

 

me and many of my friends did a 500 mile break in...

then changed the oil

 

i did a 1 mile break in and then let the racing begin. 4000 miles and going strong.

 

The way I was told to break in a motor correctly is to drive it conservatively for 500 STREET miles. Meaning stop and go traffic and not on the freeway that way the bearings get broken in properly with the revs going up and down and what not. Then change the oil after the 500 street miles and check the oil to make sure there arent any big debris in it.

 

depends if its a tight build or loose build.

 

but what about the vavletrain? no one said if you need to do anything, say, if you just had your top end rebuilt and bottom end stays the same.

i dont think it matters too much if vtec is connected or not when breaking in motor, i mean when u buy a car from honda u can go in vtec anytime u want

 

There are so many ways to break in a motor... you could take my info, or anyone else's info and do it to your motor... just depends on what the purpose of the motor is... Do you want a street break in, or a race break in? Keep in mind that the race break in will need to be inspected after the first part of the season.

 

do a search homie....there are great info about breaking in a motor. You just have to SEARCH!
