Haven't been on here in a longgg time. But guess what, I qualify for a brand new engine on warranty from burning too much oil! Right before 100k miles too, so awesome.

So I have a question, how should I break her in?


1. Keep rpms low?

2. Drive normal without red lining?

3. Break in hard by doing a lot of redlining and pulls?

4. Or do break it in with phases of low rpms, to normal, to hard driving?


Let me know what is best. I appreciate it! Thanks.

 

The dealer will instruct you on how to break in your new motor.
This is a good opportunity to upgrade the engine. I also had my engine replaced by the dealer.
Instead of leaving it stock, I replaced the OEM cams with JWT racing cams, had Robello Racing in California replace the rods and pistons and had the engine balanced. This actually lowered the compression.
When I got my engine back and installed, for the first break in period (about 2,500 miles) I only revved up to 4k RPM.
Then a complete oil change with revving to 5/6K RPM then after a 1k miles okay to push it to red line.
Yes, it was very expensive but the engine is unbelievable.
Hope this helps.
Long live the 'G'

 

Put all new internals in a brand new motor? If he replaces the pistons in the old block it wouldn't burn oil anymore and he'd have two good motors.

 

just take it easy for 500 to 1000 miles.. and then VTEC is okay after...

 

yep, the dealer gave me a new engine and they kept the old one.

 

haha vtec it.

i guess that whole 'break it in hard' theory doesn't work.

 

Your owners manual will also detail how to run-in the engine.

 

yea the manual does state some information.

but i'm sure some people here have done the 'mototune' style of breaking in an engine.

 

The instructions for the motor break-in should be at the bottom of your service receipt.
Basically, do not rev above 4k rpm for 1500 miles. It was incredibly difficult for me but it's better safe than sorry.

 

I think what a lot of people here are referring to is an easy break in...dont do it the easy way.When an engine is rebuilt for performance or stock just run it hard with the proper oil for the initial break in and seat those rings and after that just run it like normal.A boosted engine will have a different break in procedure.I ran mine hard from the day i got it and have never had a problem with it even being boosted for 80,000 miles.
I started out in the car business when i was 14 and was rebuilding engines since then and showing my age we didnt have dyno's back then.We would run them on the engine stand we had at about 3000 rpm's until the rings would seat and then done.

 

lol


just take it easy, no redlining and such

but the dealer will tell you

 

Well that was a crock.

I'm at 2400 miles and my oil is below L on the stick. Back to the sh!*@# service department I go.

 

Damn, that's crazy. Give em hell!

 

yea i go back to the service dept more than i do the doctor. the engine blows and the service they provide blows. honestly infiniti should have wrote that on their brochure for the g35 back in its day... "oh btw our engines may as well be made from volkswagen."

 

That sucks. What now? Another short-block I assume.

I hope my new engine doesn't crap out on me too..
