XR3 warm start issue resolved

Could have had another distributor - but all CVH engines were built at Bridgend and shipped out so I could be wrong on that one. The German ones have Ford Werke Aktiengesellschaft on the VIN plate. Brown cap Bosch units were rare, the blue ones the most common.

 

I guess it could have but it's only done 46k from new and it all looks original:

 

 

 

You can also tell German built ones from the lights as they are 'Hella' and Made in Germany:

Oh and it fired straight up this eve. Can heat paste make all the difference then? I had an ignition amplifyer go on the Samba. Took 3 garages to diagnose the fault! Caused non start. Also had crack in dizzy cap. Caused the engine to cut out once upto temp, after say 15miles - that was a weird one!

PROBLEM RESOLVED! Thanks for the advice everyone. Today I changed the brand new Bosch Super 4 spark plugs for some NGK ones and in doing so resolved the problem!

[meggersdog]

Excellent...nice cheap fix,well done.

[SambaS]

HELP! What is the heat paste I need between ignition module and dizzy housing, is it the same stuff used in computers between the cpu and heat sink? That is heat transfer paste. I'd think youd want heat retardent paste in my case?

[cobblers]

Nah, heat transfer paste is what you want!

 

 

I've also had terrible luck with Bosch super 4 plugs, so much that I tell everyone I know to avoid them unless that's what came in the car from new.

Bizarrely/ironically/whatever, Bosch Platinum plugs made my Samba run like poop.

im confused, i thought the paste was to stop the module getting too hot. If you put heat transfer paste on surely thats the opposite of what your trying to achieve. I am daft tho :/

[cobblers]

The module creates heat, and the paste allows this heat to transfer into the body of the distributor to maintain a more reasonable temperature.

 

As the module gets hotter, the resistance of the switching transistors increases which makes the module get hotter, which makes the resistance increase and so on until the car won't drive properly. The module will reach a temperature where it "runs away" with itself, and you lose spark quite quickly. Sticking the paste on will hopefully keep it under this temperature.

 

 

Normal grease will work for a while if you are desperate. Copper grease works even better.

[SambaS]

Ooh, I've loads of copper grease

[cobblers]

depending on how hot it gets you might need to replace it after it all runs out of the gap. Proper thermal paste isn't dear off ebay.

Or if you need it quickly, PC Wankers have it.
