Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: Rebuild Break-in....So many ways

Nathan,

My car passed 600 miles on the way to its first AutoX and I have been pounding the crap out of it ever since. Starting in '08 I've upped the abuse to 13 or 14 track weekends a year.

Car will pass 95K at the end of this month on the drive to Cresson. The engine gets maintenance when necessary. This past weekend it got new plugs when it started throwing missfire cylinder 4 codes at TWS. All the internals are OEM original.

I am MINI testament to "let things seat then drive it like your gonna use it".

Nathan your MINI does not have cruise control until Chad says it does....

 

Good discussion here..... But I'd be listening to what Chad tells you. He's the guy on deck...: D

 

Chad..... ostcount

 

Well I guess Chuck and Mark will have to come up with some good engine break-in drives! That or we can trade cars for a week...I drive like 1200 miles a so or week for work...

 

I would ask Lynn what he would do to break-in a new motor and do the exact opposite. :wink::biggrin5::devil:

 

You say that as you know Lynn can't respond

 

Nate.. the 'break in' is to the engine build. With a good engine build, good ring set, good cylinder finish.. blah..blah.. break it in like you are going to drive it!!

I would change the oil to the full syn at 300-500 miles. The oil change is to remove all the metal and gunk from the build and break in.

All the new metal and designs of parts today, sorta negates the 1000 mile break ins. MOST engines are rocking after a few minutes, check for leaks , re torque.. and run it!!

Just me.........................

I don't understand how that's a good way to break in an engine, the bores are cold relatively speaking, and unless they're heating the oil up.....I don't know. I like the idea of being able to run in the parts with no load and no combustion pressures tho.. interesting.

 

Thank God. Maybe you should give him your User Id and password or make a new one for him so he can post under a new ID like he does on the NAMless site.

( I AM KIDDING NATHAN)


Just sayin.....we all know his trickes and they are old.


Sorry back on topic.

I would drive it easy for the first few hundred of the break in.

 

Ok my bad Nathan.

:mad2:

 

What's a "trickes"? Oh and Nathan I wouldn't have asked but you had left his post up......

Ok my bad Nathan
