Plug Leads 5 & 7

[Merlin]

I saw on another Forum that apparently these 2 leads can cause a problem when running next to each other. Has anyone come across this & should it be taken seriously?--Cogs

Yes, but it's not an everyday problem, just that if you get cross-arcing it would wreck your engine.

Thanks, I will re-route one of the leads just in case.  Any others that this involves?--Cheers--Cogs

The best idea is to make sure your leads are in proper plug-lead separators... this is good practice anyway, especially on a vehicle which will be subjected to wet mud in the engine bay.

If the leads are in good condition, then they shouldn't cross-arc, if they are properly separated, the risk is further reduced.

Most V8s have clips for the leads on the side of the rocker covers, and provided you keep everything tidy, then you ought to be OK.

Yes Tim, mine are all in their respective separators nice & neat.  I thought that the separators musn't be far enough apart & you had to have them even further away from each other.  As mine are all in their correct locators I will leave them as they are.  It's an interesting learning curve indeed ownibg a CRR--Tony

From what i was told was that it is only a problem on injection systems not on carb versions , not sure if its true or not ??????????

The injection had electronic ignition, so might run at a higher voltege, plus the dizzy was in a different place so the cable routing diagram is different, but the firing order is the same and there is a recomended cable routing which I'd advise you follow.
