Default Any new ways of breaking in an engine??

It's been a long time since i did a search for ways to break in an engine and was wondering what new ideas are out there that work well!!

The last time i searched i found the non-stop method...running 6-7 tanks through the engine without turning it off.

all my o.s. motors I have broken in using the traxxas method. basically running the motor in the car. Its quick and effective, my motors last a long time. I see v-spec listed on your sig. if that is the motor in question after breaking in put a speed rod in it. the vspec rod doesn't have an oil hole and while it is proven it can last, the speed rod is more likely to last you a long time.

It seems like I've read a couple of places on here recently that they just idle a tank or two in the car, then schrooooooon, they're off to race tune, LOL

You might think I am strange for doing this, but this is how I break in .12 TG's.

Follow these steps carefully-

1. Remove Carb & Glow plug
2. Remove backplate
3. Move piston to bottom of sleeve
4. preheat oven to 350 deg F
5. Double check to see that there is no plastic or rubber on the motor
6. place motor in oven for 15 minutes
7. Remove motor, allow to cool to room temp.
8. Take apart and CLEAN EVERYTHING VERY WELL. (you'll be surprised at the junk that comes out)
9. Reassemble

then I would Idle the first tank. 2-3 tanks, blip 1/4 throttle for 2 seconds, after 3 tank lean HSN 1 hour, tanks 4-5 Blip 1/2 throttle for 2-3 seconds, After tank 5 Lean HSN an hour, Tanks 6-7 blip 3/4 throttle for 2-3 seconds. After Tank 7 lean HSN an hour, Tanks 8-9 Blip Full throttle for 2-3 seconds.

After 9th tank, to me the engine is fully broke in. My TG has about 2 1/2 gallons so far and holding up very well. And it Rips.

Yeah that is way out there in left field, more like the parking lot.

But I do see the logic behind it. Just seems like a lot of work!

For the 1st 2 tanks I remove the cooling head and only use the button head. With a rich setting it will bring the whole engine on a good temperature expanding the sleeve a lot making less forces on the crank and rod. It also reduces the scratches on the piston.

Sounds fine to me. . .i know a few people that cut a lot of the heatsink down from a old engine to get it hotter quicker.

I was thinking just the opposite. I thought it was a great idea instead of wrapping up the cooling head to keep in....just cut down the cooling area ;-) Cooling head is there for 2 reasons really. 1. Cool the engine, 2. Look flashy.

You don't care about either when breaking in an engine ;-) Keep it @ 200ish...and you're good to go. To each their own really....so many ways people do engine break ins out there. Pick a way you like and run with it. We will all swear by our own methods anyway....

That's right, besides you know my method is good for at least 12 extra gallons

One of the newest ways I can think of is the Cyrul WOT (Wide Open Throttle) method. Seems to work quite well.

I was the same way until I HAD to break one in in the morning. Worked quite well.

As for being old, well ALL of them are old, or just slight new variations on old techniques.
