MG MGB Technical - warning! oil consumption

I bought a B from a friend who had installed new Moss pistons, ( '73 B ) it has been burning oil, 125 miles / Qt. On inspection I have found the oil control rings have too much clearance in the ring land, (.008").Piston ring land is fine, the oil control ring is junk. I am now going to re-ring with Hasting Piston rings, which are known to be the best for a re-ring job.( & deglaze w/ a ball type hone)

Moss carries two different brands, which one are we talking about here?

The county pistons supplied with rings for a '72 B.

I had almost the exact same experience with my rebuild, and have done basically what you are doing (Hastings rings and honing done by a computerized machine to create the proper cross hatching process). Three thousand miles later, my oil level has not changed at all (last oil change was 2000 miles ago).
In my case I am sure the honing was not done before the engine was reassembled, meaning the rings ran on the boring tool marks, destroying the oil control.
In my case the pistons/rings that were used to start with were from AE but I doubt that would have been a problem if the bores had been honed correctly before assembly.

Erick,

If yours is the one I am thinking of, I think I remember that post complete with photos. Glad to hear it all worked out.

Does any body have a site to purchase piston rings for mg's other than the big 3?

Sandy,

Bob at Brit-Tek LTD. and Gordon at the B-Hive are both good. Bob is in New Hampshire and Gordon is in S. Carolina.

Bob is very good at packaging up kits to do a complete job.

Gordon has a very well organized web site.

Both have fair pricing and good service.

Sandy, Hastings piston rings can be ordered & supplied by any parts store. They are the ring of choice for a re-ring job, by all engine builders.
