WHY ???? The proper way to break in new piston rings.

- To properly break in piston rings in a fresh engine build is pretty simple. The most important step is making sure the engine has no leaks and ignition timing is set properly.

Total seal did a great video on using a dino for 25 minutes, 2,500 RPM with a minimum of 50lb load and as each minute past by the ring kept seating, gaging off their blow by meter.. pretty fascinating that it took 25 minutes..
I have seen that as well on the dyno. In the car it happens a little quicker if loaded properly. One time we re ringed my brothers 400 for the Pontiac event and literally finished it up the morning before the event. The first two passes the car ran 12.40's the third pass the rings seated and it went a 12.00. Picked up 4 tenths once seated. It was pretty cool to see the HP difference first hand.
Just rebuilt 78 la 360, i can start it just for a couple minutes to make sure its running before i do this? Got roller lifters, thanks for video, nice looking ride
Hi Blake, yes you can run it for roughly a half hour to an hour before taking it out to seat the rings. Just don't let it idle any more than is needed to check things over. Letting a new engine idle is hard on the rings and lifters until it has few miles on it.
The squeaking is driving me nuts....
Me too LOL. It has a fold down back seat and the latch is loose or something.
When you are doing this are you using break in oil?
Yes typically Lucas mineral base break in oil.
Old school was mixing comet and trany fluid.
I remember that from abck in the day when Comet had a mild abrasive in it. Now it wouldn't work lol. They took the silica out to protect the fiberglass tubs :)
Too bad we can’t hear what you’re saying.
Ha Ha, ya my camera guy must have had his finger over the phone mic :(
What about a turbo or supercharger? Same break in? Or should you avoid boost?
For boosted engines you can do it the same way, but like you said. Don't use any boost or very little boost. What your basically doing is get compression behind the rings to push them into the cylinder walls to seat them.
Put your seat belt on.
I really should wear it. I used to tell my daughter when she was little that I don't just in case there is an accident I can jump out LOL. I know bad joke !!!
