How many miles did you run the break-in oil ?
If you run hold it in 2nd if it's a 3 speed (or 3rd if a 4 speed) gear up to about 3500 rpm and
coast down to about a 1000 rpm, then when you get back on the throttle and it smokes alot
that indicates valve seals. The high vacuum while you are coasting draws the oil past the seals
and into the intake port, when you get back on the throttle all that oil gets burned and you
see it as smoke in the exhaust.
I actually did a break in when I first put the motor in. I fired it up, and ran it at 2500 or 3000 rpms for 20 minutes give or take. It was back in 2013 or so when I did it, so I don't remember the exact procedure I followed, but it was roughly in that range.
I bought the motor, it sat for almost a year before I put it in.
After the break in, I only put a few hundred miles on it, then it sat for a while once again. I recently started driving it more often.
I just went and drove it about 20 miles.
