Hi all,new to this board but i did contribute to old board if I could. In another thread Phil brought up the problem of HT tracking to Braided hoses. My 3L P5 Mk111 suffers from missing when cold and damp, but cures itself when warm and dry, I have checked all the usual, Could it be a tracking problem in the tube that all the leads are forced into?Would it be better to remove this and space the leads? Any thoughts,or just suck it and see?Iwould like to solve this problem as the car is my daily runner and it dont like these cold mornings,although I must say its the best rover ive had for warming up quickly.
Many thanks. Andy Mitchell

Tracking to earth is normally associated with either damp or a breakdown in insulation, so a quick fix might be to spray all the leads with a water dispersant spray, i.e WD40 and see if this helps, including spraying up the tube.
If the leads are old or you dont know how long they have been fitted to the car, the next thing is to look at replacing them with new ones.
I don't know whether removing them from the tube would be to any advantage or not. The tube would be probably the quickest to warm up and dry out.
One final point , clean out the inside of the distributor cap and spray that with WD40.

I have a 3 litre too - tracking in the tube is only a problem if the leads are worn/old. As DF says replacing them is the only option. As a temp measure spray the inside of the tube as well with WD40 or Dampstart
These tubes cw leads turn up on Ebay from time to time - they also fit P4's
Dirty/cracked dizzy cap will also cause this as will failing suppressor caps if you still have them.
My 3 litre starts first turn in all weathers and has only let me down when the battery failed

One other check I forgot until it was too late, and that is to start the car up when it's cold and in the dark. Look carefully under the bonnet and you'll be treated to a firework display if the leads are tracking with damp.
You don't say whether you garage the car overnight or leave it outside. If it's outside it is more likely to suffer with condensation on the engine.

When I needed to replace the tube on my MkIII I used rubber hose and cut the appropriate slots in it. Has worked perfectly well as an alternative to the original.

I used 19mm (3/4) black plastic electrical conduit cut similarly - it curved slightly with the engine heat but has been on now for 5 years. I have now got a complete new set of leads and proper fibre (cardboard!) tubenow but not got round to fitting it as tne engine is ready for a total overhaul

At a pinch, if you have a product called 'Spiralwrap' it would do the job nicely, as the leads can be pulled through it easily where they need to exit to the plugs. It is available in different diameters, and is normally used for tidying up cable runs.
