Windscreen washers, dribble
Is it just me? My 463 windscseen washers are rubbish, used a compressor to clear them but still only average, back one is fine, . Notice V8s have twin washers, frustrating when screen gets dirty so quickly.
My 1989 460 is OK, but the wipers themselves are rubbish - they judder and don't press onto the screen well enough. Especially the rear.
I think I need new arms with better springs in them. Someone must have a simple tip to cure the judder? Wipe the blades with something? Soap?
If the wiper links are fine then the judder is most likely to be hardened rubber profile or the angle on the arm has warped, this can happen going through mechanical car washes. Replace the wiper blades, these should be renewed every 12 to 18 months as the UV light hardens the rubbers.
Try to change to the flat profile blade rather than the conventional design. 15"/16" flat blades are available with retro fittings.
Before going to all the trouble of renewal do clean the rubber profile with a good degreasing agent (washing up liquid with some lemon juice added into it). If this does not work replace the blades.

The washers have a one way valve fitted to them to maintain line pressure for almost instant wash. These can be problematic, remove them and see if the wash jet improves. Assuming the wash pump has good operating pressure initially.
I agree with the poor jetting even when the jets operate fine, I have not tried the jets fitted to Jaguars but would have liked to try out as these jet a diffused spray across the whole screen. Try and pick some up from a breakers to try out.

Problem solved, replaced the one way valve with a new fancy alloy one, 6mm, and jets now have more power than ever,
