Yes we did "beat it to death", but I got news for you. Your engine is not out of the woods yet. I wish you the best of luck jpar, but you could still have a failure.
I would never recommend someone NOT have the inner spring removed for break in with dual valve springs.......even though as I said in the other thread I have done it myself in the past. Zinc in oil was not a problem back then.
The biggest thing is if you are just BOUND to do it with both springs installed, don't let the engine drop below about 3K RPM. That way plenty of splash lubrication will be happening and you will be much less likely to do damage.
Just because you got through break in does not necessarily mean you will not incur damage from not leaving the inner springs out. Only time will answer that. It is still best to leave the inner springs out. Whether you do or not is up to you and a risk you take and are responsible for 100%.
first, I did not make a recommendation to not take the springs out. I actually would recommend it if he has the time, inclination and all that stuff.
second, I never feel I'll be "out of the woods" as far as the motor goes given the way I plan to drive it.
third, (and this is the big third)- I've also read online (Bonjour - I'm a supermodel) where a guy because of the high RPM's for break in lost a retainer (because of low spring pressure/high lift cam) and had a car suffer catastrophic failure! so there could actually be arguments for not doing it, but again I recommend doing it I guess because everyone says you should and I wouldn't want to steer somebody the wrong way either way. I would use the most expensive breaking the oil you could find with zinc .
