Having partially cured the starting issues by replacing the carb (starts fine when cold now but not at all when hot) i have now gone on a couple of longer trips and the engine has given the same symptoms each time. After about 20 mins of country driving on A roads i am getting the odd whiff of burning oil, once i the slow down for a junction or traffic the oil warning light flickers on at low revs followed by very poor running, almost like it`s on one cylinder and it`s then a foot to the floor job to reach 20mph. This morning on the way to work it cleared itself after a couple of miles but this evening on the way home it didn`t, i have just gone out to the car and there is quite a decent sized pool of oil that has dripped off the bottom of the tinwork on the left side of the engine and the air filter and all the pipes are flooded with oil. This is obviously all going straight into the carb which is causing the rough running issues. In addition i replaced the oil filler cap as the old one had no disk under the spring at the bottom, after todays runs this cap has lost it`s disk. There is no obvious sign of oil smoke from the exhuast. This sounds like an engine out job but what is the cause, wouldn`t rings produce a lot of smoke out the exhuast? Any help or advice appreciated..........Martin

well try running the engine with the rocker cover breather off into a container and see how much oil is being forced out that way it sounds like that is where its coming from from your description and that you are getting too much oil pressure, could be that the bores are worn, rings etc. whats the mileage of the engine?
