I looked and could not find the torques specs for the conrod nuts.  This is a 2.1 L regular van.  87 model.
Also, I must say, I am flabbergasted to see that there is no torque listing in the Bentley of all the bolts and nuts of importance on one page.  I had to gather all I needed for assembling the engine from fifty different pages, hunting for the torque figures.  Kind of non germanic arrangement.  I noticed that many essentials are missing or ignored or you just have to guess.  Oh vell...  ve are not all the same.
