How to: Break-In a New Engine

[galantebeige]

It's amazing to see to way different approaches to the same problem, and both being from people who know what are talking about....
And still, both work fine! aparently. :shock:

Like in all fields, there are proponents and oponents, for any given theory at the same time.

So, any other ideas? Maybe just flip a coin, huh... just kidding.

Do you have any logical reasoning in your theory? Sure you say you know your stuff, you rebuilt your engine which is running fine, but why take it easy? Like scootin said, the break-in takes place within the first 50miles...

I break in my motor the manufacturer recommended way. If they say run the hell out of it, I'll do just that. If they say don't go above 2k RPM and stay below 20 mph then I do so. If they say I have to do the hokey-pokey and run naked through a police station...I'd reconsider. But I'll tell you how not to break in an engine though...my friend bought a new supercharged Cobra and basically redlined it the entire time. I think he said something about his rings not sealing and voiding his factory warranty, so he has to pay for repairs out of pocket.

A manufacturer would find it pretty difficult to tell their buyers to run the piss out of the car, because god knows what kind of lawsuits that could result in. Sure, the old way works, the new way just works better.

As did I. Minus the whole 6g72, plus a B18b1...My block was bare. Completely. Every oil passage was open and cleaned, every bearing removed and checked...and my motor runs strong and great, too

Hit me up on AIM, mang

my theory behind my way isn't 100% for making a good seal. it has partially to do with how the motor was built. if you forget something, or something just isn't right with the motor, and you leave and start flyin around, the damage is gonna be a lot worse than takin it easy. i think this thread should be limited to people, giving information from personal experience and personal knowledge. not people going to google.com and typing "how to break in a motor" then pasting it here thinking they know their shit. i've been around many many cars with full rebuilds that took it easy for a lil while and are running at 500+ hp right now. like i said, its all personal preference, neither way has ever been proved "right or wrong." i just don't see any benefit to beating the piss out of a brand new motor, over driving it normal. my way worked great, and i'm stickin to it. obviously other peoples ways worked too, and they are sticking to them. i personally don't care how ya break in your motor, just giving my opinion on how i would do it.

Either way, if you're at 2k rpms or 7k rpms, and you throw a rod or a rod bolt, you're still going to put it straight through your block or oil pan. Just put everything together right, and this own't be an issue!

Best Idea yet.

Whoa Whoa...for your information, I went to Yahoo!

[galantebeige]

I agree, that is what this site should be about, people like me (beginners ) asking questions and people like you guys (experts 8) ), generously providing information from your personal knowledge/experience.

[galantebeige]

It's all cool, scootin.... 8) . I bet there is stuff you know nothing about too...
I made this thread "sticky", and I added a poll, it will be interesting to see the results (hopefully with enough respondents)

[Galant_01]

Someone needs to distinguish if we are talking about breaking in a brand new car or a rebuild engine because they are 2 different methods.

And by the way I did not pull it off Google, I got it off my owners manual!

[rainfever]

There are very many "theories" on how to do this. But I am going to follow this guys when I break in my engine

http://www.mototuneusa.com/break_in_secrets.htm

I remember someone bringing this site up over at www.rs25.com, i just remember them saying the dude was breaking in Bullet bikes (street bikes) and that is a totally different ball game.

I would never follow that advice, but hell, its your car, do what you want with it. However i would like you to keep us posted, if it destroys your motor, dont be shy about it, tell us...

[TWISTED II]

5,000 miles on my motor now, still runs great. not my car anymore, but thats what they tell me, lol.

[sethmo]

I found that site on DSMTUners.com where they were discussing how to break in freshly rebuilt motors. A lot of members there follow that "theory" and their motors still run strong.
