Hi, does anyone have service information on the overhaul of the 4/1.4 bore injectors and a parts breakdown?
Thanks in advance.

How far into it do you want to get?? Here's some initial stuff....don't think there is much in the way of parts available unless someone has a stash in the out back:) :)

You'll probably have to make your own wrench.....1-3/4 inch size.
I'll post disassembly/assembly instructions in the morning.....way past my bed time now:)
