eh? why is it everytime you describe a problem more details appear afterwards? list all the symptoms, leave nothing out.
how long has it been knocking under the rocker cover?
First heard the knocking in November.
Took it to TJhonstone in Troon, he said he couldn't find anything.
is it losing water or not?
Not that I can see, as I said topped up last monday- drove the car Tuesday & Wednesday to work & back.
Engine was only rough on cold start as I explained over the phone, but holding the throttle open for approx 30 seconds sorted that out.
list all the symptoms, leave nothing out.
OK:
1) Engine is still mis- firing.
2) Below 2500RPM the engine is very rough & shakes
3) Above 2500RPM the engine seems ok
4) 2nd Plug in from the Expansion Tank had oil on the thread. but NO Oil on the Electrode
5) I've no idea what the Electorde Gap is, as I don't know where I put my feeler gauages are
Plugs were changed early September, approx 1 week before the MOT. Plugs used are NGK- BKR5EZ & were gapped correctly at the time of fitting (when I last used my feeler gauges).
I have put 4 brand new HT leads on, which has made little or no difference.
We have tryed swapping the leads about at the coil- no change.
