I think some oil is comming into contact with the disrtibutor as I have experinced some blue smoke from the bonnet, backfiring and poor running.
Do you thing that leakeage from the top of the dipstick could cause these symptoms.
I've also noticed when the car is not exhibiting these symptoms that it pulls badly uphill. Could this be a symptom of a worn distributor (mixture, plugs, leads, and coil ok).
Thanks
