Re: Should it stay or should it go? (k20a)
Rather than assuming that the piston rings are bad...
I would perform an engine compression test. Compare dry and wet readings. Burning oil could be simple problem as clogged PCV/oil seperator system. Also, could be problem with valves.
The reason that I ask...
Most likely, the engine did not burn oil at 92K miles when you bought it. Now at 138K miles, it is burning oil even though you performed oil changes at regular intervals. Rings just don't wear out like that. This leads me to believe that oil burning problem lies somewhere else outside of wore piston rings.

I bought my 96 850 turbo from this website with 92K miles. It now has 138K miles and: -at idle it smokes - burns oil |
