I know this topic has been covered before but after days of searching, I still haven't found an answer.
Why does my engine sound like a diesel? I changed my oil ( used castrol gtx 10w-30 with a bosch filter) and it now sounds like a diesel?
I can't determine if the sound comes from the top of the motor or the bottom. They only way to quiet the sound is by adding another 1/2 quart of oil!! That means I have 6 1/2 quarts in there! I really don't want to blow a seal with too much oil but It really sounds bad, and it doesn't go away at any rpm's. Any ideas??? I have an 03 wrangler with the 4.0 5 speed. it has 77000 miles. Thanks
