How do you know that ring seal can not happen at low RPM's? I don't comprehend.

 

Have you ever seen the longshoremen unload an auto carrier? They take a cold engine, shove the pedal to the metal, jam the gears, spin the wheels drive off the ship as fast as they can and park it in the holding lot on the dock. Then they get in the shuttle bus and go back and do it again until the ship is unloaded and they can go home. Every car, every time. The faster they go, the sooner they are done. They don't answer to anyone. The manufacturer usually has a body shop and repair facility right there to fix the bent ones. It has been like that for many years. Some ports are better than others. But manufacturers just live with it.

Firstly, I apologize for typing cylinder head. Silly me, I mean to type the piston head anywhere I typed cylinder head. Thank you Mr. Donovan for pointing out that clerical error.

After being brought to the point where I have to finish a debate that I never wanted in the begining, I have done more research. And yes the gasses push the ring seals against the walls of the cylinder, thank you for clueing me in Mr. Donovan again. This action merely puts a physical barrior between the gasses and the next ring. The actual part that is doing the work of holding back the pressure is what I have come to learn as the "ring land". In any case I apologize to the person who started this post, I should have never posted such a flame worthy post in your topic. I admitted from the beginning that I did not know all that I was talking about, and I still have a long way to go, but piece by piece, debate by debate, and discussion by discussion i learn more and more. Sadly, this debate has shown me once again that people are terribly hard to deal with and would rather go on offesives than actually discuss the issue. I hope that later on when I have a topic that is equally dangerous to post, that I will not keep silent and stupid in fear of being humiliated by people I had hoped to call friends. My apologies, Boludo.

 

Here's another argument for following the break-in procedures closely. The ECU keeps track of revs etc... if you ever do have a problem with the motor under warranty, how hard would it be for the manufacturer to claim it was your fault for exceeding max RPM during break-in?

On the flip side, I have picked two BMW's up in Munich via Euro Delivery. Both cars were driven HARD within the first 10 miles. Both used no oil and ran flawlessly. Conversely, on a couple of BMW's that were broken-in by the book they used lots of oil. I dunno... I kinda think it is not that important.

I wonder if part of the reason for break-in restrictions is to get the consumer familiar with the car for a period of time before really hammering on it. You know... prevent accidents and reduce liability and the like. There goes the lawyer again... always worrying about liability.

 

I took the stay by the book break-in, except for the odd short burst, after 1/2 way through.

I now have 50k+ miles on my MC. I have changed the oil twice as often as recomended. I have had to add a little more than a quart of oil, since day one.

I look forward to the next 50k+ miles:smile:

Unless you are being nuts out of the box, the warrenty will be long over.
I think were talking high miles here, 150k plus.

Not sure, but the ecu does not keep a long term time line. It may remember what just happened, but forgets things as they change.

 

Against all manufacturer advice, our MA told us to drive it normal, then hard every once and awhile. So when I picked her up, My girl and I drove 45 min up the highway, avg 70-85mph, then into the mountains, up the twisty canyons. It was at night, though, and it began sonwing as we climbed higher, so I wasn't driving very hard. We spent the night at a great hotel, and woke up to a foot of snow. A few hours to allow the plows to go thru, we drove back to Denver through more mountain passes and roads, enjoying a 3/4 rpm range, but still being nice. We let it warm up for a minute in cold weather, stay well away from redline (the MC seems like it starts to actually loose HP after 5500rpms) and avoid dumping the clutch or really banging any gears.


I think the break in period is obvious to most of us, but these days companies have to put warnings on everything to protect against idiots.
"WARNING: Contents is hot!" on coffee, for goodness sake.

Vary rpms and conditions, but don't be stupid and you'll be fine. The engine is tough, any major problems will come out no matter how you drive within the warrenty period.

Good luck-:smile:

Go back and read the break in procedure by the motorcycle guy .I am a former Aircraft mechanic and have built over 60 race engines. Your flying fish annology is not even one that deserves commenting on ,Joe.

 

I used to work at a BMW motorcycle dealership. We always subscribed to the "ride it hard" theory and we had some very high mileage strong running bikes that evolved over the years.
