I am curious which sensors are going to be ruined by over filling the oil??? Plus how is the cat going to get ruined as well???
Neither, over filling the oil will do nothing more than get in the way of the crank when it is rotating and sap some power from having to cut its way through the oil.
I stated this because this is what happened to my VW Jetta when the stealership overfilled it [u]excessively. Let's just say that they covered everything that needed to be replaced.
If you check your owners mannual, it tells you not to overfill. It [u]can do more than "sap some power." Overfilling your engine oil can result in excessive internal air pressures which can cause gaskets and seals to fail.
It is important not to overfill the engine oil system. There is some thought that overfilling is worse then slight under filling, as the excessive oil causes the crank to froth the oil, meaning air is literally beaten into the oil bath, much like air is beaten into egg whites for some baking recipes. Which you mean a major loss of oiling/oil pressure in the total system.
Now, I got this information below from car talk but I am sure that the same prinicpals apply here.
Lesson No. 5 - Signs of Coolant Leak
Brown bubbles or a dried crusty-brown residue above the oil level line on the dipstick could be an indication that coolant (water and antifreeze) has leaked into your engine. The oil on the dipstick might even look like chocolate milk. Never taste motor oil as a test for antifreeze.
Another prominent indication of coolant leak is white exhaust smoke that has a sweet odor. In this case, the dipstick oil level may actually rise, indicating a significant amount of coolant has leaked into the crankcase.
To confirm a coolant leak, shut off the engine, let it set for an hour or two, unthread the drain plug and use a clear glass or plastic bottle to catch the liquid. Because both water and antifreeze are heavier than oil, they will puddle up at the bottom of the oil pan. Collect a couple of ounces of fluid and immediately retighten the drain. Inspect the fluid for glycol and water. Glycol and water often look like a thick mayonnaise-like paste, depending on how long the coolant has been in the crankcase. You might also detect a sweet antifreeze smell.
If you have detected coolant in your motor oil, your engine should be taken in for immediate service.
Good luck! Hope this helps you.
