A simple test is to take a clean good morning towel wrap your exhaust start the car, then take the towel and soak it in a small pail of hot water.take that water, then put it in the freezer, but if you have some chemical solutions , you are able to detect the amount of oil in the water.After frozen if you can see droplets of oil, you would have some oil going into your combustion chamber for sure. Mind you there are some remnents of the oil in the towel,but you could further do an ash test, but this will require a full lab setup. From there the volume of oil will be able to calculated how much oil is being consumed by the engine, compared with the theoretical value, the excess oil will indicate a leak in the combustion. Sounds alittle bit complicated ya!</blockquote>
