Whew, this post is very near and dear to my heart. I had the SAME problem. And I was where you are...people suggesting the bore was bad, rings broken, tear down the engine. There are too many things to do first before getting that drastic. So, here's my advice based on having the same problem:

Check the following first:

1.) Are ALL plugs fouled from oil? Only one or two? Only one side or both? If fouled, all over or just one side (put in a new plug and make about a 2 mile run then pull the plug quickly). This will isolate the problem.

2.) Did your intake gaskets slip and you are sucking oil from under the intake into the head? Were the haeds milled or angle cut causing a gap between the intake and heads?

3.) Are you sucking oil from the PCV? Take the PCV out and drive it. Any smoke? No, add a catch can between your vacuum line and the PCV valve.

4.) Find a fouled plug, replace it, then replace the valve seals on that cylinder. Heavily oiled top ends can suck oil past bad seals (even marginally bad seals). This was my problem.

5.) Leakdown test will show bad rings or cylinder wear. (Compression test is not good enough). You want less than 8% loss across all cylinders. It's so hard to believe you have bad rings or bore job. Unless you cracked a ring, scraped a cylinder, or installed the rings where all openings lined up, it's just too hard to believe there's a bad bore or cylinder related problem. However, you did say chrome rings...they take forever to seat. Possibly up to a couple thousand miles.

If it turns out that the rings are not seated, let them break in naturally. Don't do anything crazy like adding cleanser, transmission fluid, cutting oil, or let your engine get hot. That is not going to do you any favors in the long run...unless you like scrapping messed up iron and aluminum!

By the way, how much oil are you loosing?

Keep us posted on what you find above...
