compression ring- top most ring -maintain desired pressure with secondary ring in combustion chamber.oil rings- below secondary rings- ment for lubrication,heat transfer and also work as oil scraper from cylinder walls.
broken oil scraper ring, low oil level.
1966 type 1 were either 1194cc which was 77mm with 2.5mm top and oil ring1300 was also 77mm but with 2mm top and oil scraper ring 1500 was 83mm with 2mm top and scraper. However, you need to pull the engine apart and measure because you never know what has been done to it.
Olive OilThey used oils, and then scraped the oil off after their bath using a scraper made of metal or bone.
A palette scraper is used to slide paint on a canvas from one place to another. A palette scraper is also used to blend paints on a painter's palette.
Worn piston rings would be the first culprit. Oil gets shot up into the bottom of the piston to cool it, and also to form a lubricating layer between the piston and the cylinder walls. When the scraper ring wears out, oil passes through it.
Most commonly the bottom ring will be the Oil Controlring.(Control added by amclaussen.)Oil control ring is correct. It is used to keep the cylinder lubricated as the piston goes up and down. The first two top rings are for compression. However, the 2nd from the top ring is also a wipper ring. Used to keep oil from getting into the combustion chamber.(~Decker)

The lowest ring is the oil ring
it a kitchen tools used in baking ... For me I think it is what you use to scrape off dirt
oil scraper rings are the rings on the pistons that scrape the excess oil off the cylander walls on the down stroke of each piston. this is done to remove excess oil from the combustion chamber in normal operation of an engine if this was not done you would always burn oil and forever be topping up oil in engine
After a prolonged service in a crude oil line wax deposits will be formed and reduce effective diameter for required flow .It is necessary to clean the long line effectively by launching a scraper in the pipeline and will made to travel along the line and it will clean the inner walls of pipe line by scraping. To do this on line you need to have built in scraper launcher in original design it self, or else you have to shut down the line and fix scraper launcher to do this operation. scraper is a metallic flexible object which will have outside diameter exactly to suit inside diameter of pipe to be cleaned. scraper launcher is a pipe with isolation valves and blind at on end to insert the scraper.
