Chevy Yukon Engine Noises

Reader Question Had oil changed in a 2000 Yukon (147,000 Miles) by a dealership. Around the time that the new oil change was required (150,000 Miles about 3000 miles on the oil) the engine started to make a terrible knocking/whining noise with no check engine light.

When I took the vehicle into the shop, it showed that the oil was overfilled by about 2 inches over the full mark. Is it possible for an engine to hold that much oil over a 3000 mile period without blowing it out? Also, could the oil being overfilled cause this engine noise that I am hearing? If it can, what would be the most likely cause of the noise?

The shop where the vehicle is at, is telling me that they will have to take off the head to see where it is coming from because they have no idea what is making the noise, and they believe that it is under the head. Do you have any suggestions?

Luke

Hey there Luke,

This is going to be a tough call as to what really happened. It is possible for the engine to be overfilled by that amount and not blow out the excess oil somewhere. I would say that there is a 50% chance that the excess oil caused your engine noise/knock.

What tends to happen when there is excess oil inside the engine block
is the oil becomes agitated and foams up, causing the oil pump to suck up foamed oil/air and not the true liquid oil that is should suck up and pump through out the engine.

So, basically what happens is the engine runs out of oil since the pump is not pumping the oil in liquid form…..the engine runs out of oil pressure and internal damage occurs.
