[Vwdiesel] RE: Difference between TD and NA longblock

[Libbybapa at wmconnect.com]

What are the differences between the '86 to '92 turbodiesel longblock and the 
naturally aspirated diesel volkswagen longblock?   Anyone car to share their 
knowledge??  Are the rings the same?  I was told by an "Expert" (bigtime, big 
city, german parts establishment) that after '86 there was no difference 
between the TD and the NA vw diesel longblock.  Despite my pointing out the 
differences that Bentley talks about, I was told that post '86 there was no 
difference.  I pointed out that the heads had different part #'s in the casting (just 
one letter-the T before the D at the end).  I was told there was still no 
difference?? Any opinions, facts?? Also can the N/a shortblock be retrofit with the 
oil squirters and used as turbo?  I have read that the head gaskets are 
different, and also been told by others that they are not different.  What about 
the rings?  Help would really be appreciated from any Knowledgeable folks.
