Fwd: Re: [Vwdiesel] compression test results on stinky ('89 1.6 na)

[Bart Wineland]

Unfortunately it is using a lot of oil about 1qt. every 200 miles but it 
does start well. Deep down I know the only real thing to do is re-ring when 
I can.  Val asked about the piston lands on the last rebuild but I don't 
know. I bought the engine as a fresh rebuild knowing full well that can 
mean anything but I was assured it had all new bearings, rings, valve job, 
water and oil pumps but who knows. I know it was not bored and he reused 
the original pistons.  I was actually kidding about adding the Bon-Ami but 
I remember I think Hagar saying that was a good way to really wash the 
cylinders after honing/glaze breaking to leave a good scoured surface for 
the rings so I just wondered how it would do as an additive to maybe 
shortcut the process :)
