I took a look at my MK2 Bentley,
'85 to '92.
Figure 7.1 shows the same lubrication flow diagram as the Rabbit Bentley.
intermediate shaft and head have their own supply routes.
I can't imagine them taking oil from the block, then sending it through the crank before it goes to the head, like the FAQs suggest.
Now, I just got an '85, '86 GTI, Golf, and Jetta,
"Official Factory Repair Manual" and on pages 13.2 and 13.3 they have the diagram that was squeezed onto page 39 of the MK2 "Service Manual",..
the blown up picture of the block/crank/bearings. (actually looks like they put the same picture on the next 2 pages also, ha)
Instead of saying:
"lower main bearing"
"shell (#'s 1,2,4,5)"
Like the MK2 "service manual".
In the same place; the "Official Factory Repair Manual" says:
Bearing shell 1,2,4 and 5
for cap 1, 2 and 5 without
oil groove
cover 4 with oil groove
do not interchange worn bearing shells (doh)
I'm still not sure why #4 is special,
all the mains supply 1 rod except #1.
