Breaking in a new engine....

Hi guys...Been a while since I can say I'm breatking in an engine. But I just want to make sure that I'm doing it the best possible way. Looking forward to having fun with the ride once it's ready to go.

But what I'm doing is just driving her not all that hard. Between 3k-4k rpm...Not all that fast. And planning on driving her this way for the first five hundred miles then change the oil in case of any garbage in there. Then start to push her a little more...Not much, but just to work her out and loosen her up.

Let me know what you think.

And keep altering the engine RPM - don't keep running at the same RPM.

Just keep moving the loud pedal a little to avoid the possibility of a harmonic in the bearings.

And when you change your oil and filter, also adjust the valves. Check the Forum Search for various recommendations on head bolt re-torqueing.

Two schools of thought. First is an 'easy' break-in such as you describe.

Second is start motor and set throttle to 2,500-3,000 for 15 minutes, then swap the oil and filter and you're good to go (rings seat in about 10 min.).

I've used both methods through the years several times. Both work, but (and it's only anecdotal) the ones I have done the easy break-in to haven't lasted as long and seemed to tire sooner. If I were breaking-in an engine today, I'd use method #2.

Be sure to use Dino Oil (not synthetic) for the break-in.

As mentioned, adjust valves and re-torque the head when you change the oil (but be certain motor is cold).

Happy Motoring!

Cheers!

I used Brad Penn break in oil. Start her up and let her run for about 15 minutes at 2000 to 3500 rpm. I went and idled it up and down about every 2 minutes or so. After that I got in and hauled ass. but even after the initial break in I did I was very careful not to drive at one speed for a long time. Don't take a road trip for say the first 500 miles or so. I took back roads to work that had lots of stops and goes
