Twin plug heads
Please forgive this newbie to your site if I I'm in the wrong place with this - perhaps a moderator can relocate it - but I have a question and I'm literally itching to have it answered.
My car is a European two seater, mid engined, turbo charged with 6 sp sequential gearbox and a reputation for frail engines, the existing explanation for which I do not find plausible.
That'll be a smart then! Why I am on an Alfa owners site is this. I suspect the problem with the smart is related to failure of a plug or plug lead, leaving one or more cylinders firing on only one plug rather than the two per cylinder it should be firing on. So what I am asking here is if anyone has had this happen on a TS Alfa, and what the outcome was? I would expect the 8V models to suffer more than the engines with 4 valves per cylinder. So if anyone has experienced failure of one plug - with the affected cylinder still firing on the remaining plug, will you please please please reply to this post with as much information as you can?
Possible / probable symptoms are burned exhaust valve and / or overheated piston, possibly only affecting one cylinder. It is possible that the coil layout may make this impossible, but my suspicion is it could have happened.
If you can help me here, I promise your input will be appreciated. Many thanks for reading so far.
