So, I was having problems getting my new induction type timing light working continuously (where an induction lead is clamped over the HT lead)...it worked ok on #1 but only occasionally on #4. The engine is firing ok on all cylinders, I know this. But to get accurate timing I decided to use the timing light.
Wondering why I was getting the light to work only intermittently I was having a good probe around the #4 HT lead when I noticed a few drops of water......on further investigation I discovered this was running out of the HT lead. I made a slight cut through the outer insulation and water came running out. I'm thinking the presence of this water may have been causing the timing light not to work. Has anyone else ever experience this?
Anyway, replacing the HT leads is not straight-forward on the 550K as I'm sure you all know. I understand it requires 'breaking-into' the sealed coils and patching the thing up again. The idea was to replace just the HT leads but perhaps the coils could do with being replaced too as I'm sure there is dampness in there too. I am however, getting a nice bright blue spark so I just don't know what to do.
It would obviously be more cost-effective just to change the leads and persevere with the difficult fitting work at the coils - I reckon I could manage this ok. The leads can be bought off eBay very cheaply. I would be interested to hear other people's thoughts on this situation.
