Avoiding Jaguar V6 mess: the consequences of excess or lack of oil in your engine.
Regularly checking and replacing your oil is crucial. It serves as the vital fluid for your engine, responsible for keeping all the intricate metal components lubricated and functioning together to produce that powerful horsepower. Insufficient oil can result in disastrous consequences. However, having an excess amount of oil can be just as detrimental, as evidenced by the breakdown of a Jaguar engine that was overfilled.Maintaining a consistent schedule for checking and changing your oil is highly important. This is because it acts as the life force for your engine, which has the important responsibility of providing lubrication to the intricate combination of metallic pieces that work harmoniously to generate significant levels of horsepower. Dealing with oil levels that fall below what is necessary can have severe ramifications. However, it is also essential to note that too much oil can yield equally negative outcomes, as demonstrated by the dismantling of an excessively filled engine in a Jaguar.
Eric, the creator of the I Do Cars YouTube channel, was able to acquire a 3.0-liter supercharged V6 engine from a 2017 Jaguar XE sedan that had failed due to being excessively filled with oil. The salvage yard where he purchased the engine reported that a staggering nine quarts of oil were drained from the pan, even though the maximum capacity for this specific engine is only 5.7 quarts.
Upon inspection of the cylinder heads, indications of a potential issue were found. Despite having a relatively low mileage of 66,000 miles, the components appeared to be in decent condition. However, upon further examination, it was discovered that there were metal particles present in the oil filter and scarring on the cam journals, suggesting severe damage within the engine block.
As expected, upon removing the heads, Eric uncovers that the first two pistons are not correctly attached to the crankshaft. Moreover, he notices that they have previously come into contact with the head, which is an abnormal occurrence during regular operation. A thorough inspection of the oil pans exposes a significant amount of destroyed rod bearing material, including some significantly large pieces. This clarifies the reason behind the pistons being loose.
Upon removing the pistons, it becomes evident that there is a considerable amount of scorched metal caked on the base of the connecting rods, along with extensive harm to the cylinder walls. This occurs when an engine is filled beyond its recommended capacity, causing the crankshaft to agitate the surplus oil in the crankcase, turning it into a frothy consistency. As this foam makes its way into the oil pump and mixes with the lubricating oil, it causes air bubbles to form, rendering the oil ineffective at protecting the metal components. The outcome is a substantial amount of friction and intense heat, which if left unaddressed, can rapidly destroy the entire engine. And that is precisely what transpired in this case.
Consider this Jaguar V6’s demise as a reminder to educate oneself on correctly inspecting oil levels. Otherwise, risk facing a completely damaged engine.
