Thread: Discovery 1 replacement distributor

Nothing wrong with the power spark ones except they're probably made in China and subject to their hit and miss (haha) quality controls. Just make sure you have the correct model though, they do vary over the years.

Just about every part of a distributor is separately fixable, e.g. vacuum advance, pickup assembly, bushes etc. The only part that is likely to cause a miss is the air gap in the pickup. However the likeliest reason for the misfire is the electronic ignition module which on your vehicle should be behind the coil, adjacent to the radiator, passenger side. These are easy to replace with a Bosch BIM024 module, they were used on loads of Australian vehicles in the late 80's.

My thread on the conversion is here:

A " Performance Ignition " aka scorcher distributor will make a vast difference or just rebuild your dizzy using a bosch module and other new parts.

OK, so what is it that would separate the different distributors over the years?

Yeah I've heard the ignition modules have a habit of failing (like most things that are 20 yes old haha) why would you do a conversion as opposed to just replacing the module with a new one the same just out of interest?

So I'll avoid the powers park one, do the performance ignition guys rebuild distributors? Or is it just a retailer of replacement dizzys? They're quite close to me so I'll probably give them a call, as even if the misfire is only being caused by the ignition module this distributor has really excessive shaft play.

I don't really have know how or time to do the work myself and at the same time I don't have heaps of money at the same time haha so I realise I may be asking a bit much..

Performance Ignition rebuild as well as build their own distributors, Bee utey can answer the changes better but as far as i know the Lucas dizzy hasnt changed much from the time they went electronic some time in the mid eighties .
The bosch module is superior to the old lucas part, lasts longer and cheap to replace.

Your 96 distributor doesn't have an oil pump drive dog on the bottom as the serpentine belt engines changed to a crankshaft driven pump. It also has a different connector plug as it runs a remote ignition module instead of one bolted to the dissy. Earlier RRC dissys had remote modules too but of course with a different plug.

Lucas original modules are marginal at best, back when D1s were new they had a 50% failure rate. They were a sick joke. Aftermarket replacement modules are dodgier still. Lucas replacement modules are now just as likely to be Chinese made in a Lucas box. In comparison the Bosch module has a 1% failure rate and is now sourced from Germany.

Personally I suggest you find a good condition used distributor from a wreckers, they are usually quite trouble free compared to the replacement ones.

I didnt say it was identical , operationaly its the same ie old tech.
