I am writing this trying to help Shawn,Nick and Gavrik.  ----and ALL newbies.

After seeing Gavrik Petersons   reboring and  overhaul of his 1.6LNA Rabbit diesel ?

I say YES it is worth the money and time NOW. ----considering fuel pricing.
Loren pointed out to me that  my way of checking piston fit was near impossible to do.
Simple really --- I did not explain it right.

I learned this procedure from a mechanic at Finning Tractor  Van.BC.

Clean bore  --clean Piston NO RINGS or pin.  Long feeler gauge blades  about 12 " american inches.

With a 5 thou blade in cylinder and piston slides right through --on its own weight ?    NO
good for a diesel VW.  You need a bigger piston------  well you DIY's gets the drift ?---if NOT ?.
Leave it ALL to a good shop.  ----BUT make sure you tell them to fit on the THIGHT side of specks.

For a gasser guy like me ? ---having seen a lot of frozen pistons  ---to get to the diesel
fit was a challenge. ----but remember the lube quality of diesel fuel compared to gasoline. 
On the TURBO    ---the squirters not only COOLS   but they lubricate cylinders.

In Denmark we had a saying  -----"Tight as a Mouses Ear" -------- 

I flunked English and I still have no MS speller. --------so if you do not understand---?
just ask and I shall explain.


PS:  where to find a GOOD rebuilder ?   --I had super luck with  "Allied Rebuilders" in Vancouver BC .Canada.
