oil smoke

[AMXguy]

Ok my 383 has 1000 miles now , it has Ross pistons which in my opinion are a little lose and clatter pretty good until they warm up. the heads have new valves and positive valve seals and this was all done by a good shop before I bought the car. my question is this engine smokes ( blue so it's oil ) a little more before it warm up but it smokes a little most of the time, compression , idle, acceleration but mostly on shifts and around town driving. there is almost no blow by at all so could rings still be the problem ? it runs perfect and the little smoking it does only hurts my pride but nothing else. is this something any of you live with ? maybe a forged piston effect I'm not sure?  I hate to tear it down and start over but this is driving me nuts.

CHrome moly rings?

Boy that I don't know , but I'd guess so.

I've seen chrome-moly rings take 5000 miles to seat in.  The smoother the cylinder wall finish, the longer it takes.  Had a '68 hemi Runner back in the day that ate spark plugs and smoked like a freight train for the first 5000 miles.  Then it suddenly stopped and was awesome for the next 30,000 till I sold it.......   Give it some more time and see what happens.  That's my advice anyway.......     Oldschool

work it hard , Dynos are awesome for this , it may be worth pulling it apart honing the cylinders & using a plasma moly ring set , it is possible some of the rings were installed upside down or were for the wrong bore as well so they have excessive gap ?

 ...Flog it while its new and might still have a little warrenty.

Old, I think you have it backwaords... Moly faced rings must have a very smooth surface finish to break in properly. But when they have that, and it's clean, they seat within minutes of the first fireup. However, I find it's not real common for shops to give the right extra smooth finish. The end result is, the moly is scrubbed off the rings, and they act like std iron rings that take 500-1000 miles to seat. The trick is to load it like CP said. If it doesnt go away, pay careful attention to the carburetor. If it's rich, it may be "washing out" the rings. Where excess fuel removes the oil, and the rings dont seal well. A leakdown test would tell you if the rings have or have not fully seated. I had to re-ring a 383 last year that had gotten 300 miles in 4 years since it was rebuilt. The rings never fully seated because of cold starts and "just warming it up in the garage" on the part of the owner.
