The daughter's d16y8 motor has had the block cleaned up and honed by the machine shop and got new rings. My internet sleuthing has led me to three different camps: one side says to start it up and immediately run it at 2000 RPM or so for a while to seat the rings, another says to get it started, set the timing, let it warm up, and then hold it at 2k for a few minutes, and a third says to just baby it for 500 miles.
So what's the right thing to do when we're ready to fire this engine for the first time?
I just always start em up and drive em and change the oil after about 500 miles.
I don't think the factory breaks in every new car engine.
In reply to wvumtnbkr :
That's what I've always done in the past and it's always seemed to work out. Didn't know if I was just lucky....
Boostedboiz has taught me that you just put it on the chip at first start...
Do not recommend.
How I do it:
Start verify no leaks, bad noises, fire, etc
Idle to temp (On Hondas adjust valves)
Change oil and filter
Practice the way you play... (If its a street car engine drive it like one for 500mi and then do another oil and filter change, if its going to sit on the chip... sit it on the chip)
Running at 2000rpm for a while was a thing for older cars with flat tappets, in order to break in the camshaft. I don't know if that applies to your engine.
Ensure that it stays running, find a long straight stretch of road, floor it in like 3rd gear, then let off in gear until it about stalls. Done. Seating in rings isn't like a flat tappet cam. You want load on them. Do it once and should be done.
