Hello!
Hello!
Great articles about EGR, 3 signs of head gasket failure and this one. Very helpful. I have 1/3 of the symptoms as described in the 3 signs of a head gasket failure article. Very occasionally I get the aggressive rattle in the engine. This has happened 10 or less times over 2 years. A previous mechanic said it happens when the oil gets low. I check the oil more often, add some if needed and that seems to stave off the rattle/knock.They last a short bit of time or I turn it off and usually starts up okay after that.
Would this still be a head gasket problem or something else? Coolant levels are good and oil change last weekend showed normal color oil.
I'm doing my research now on how to change a head gasket but want to make sure it's the right move to make. I'm not real experienced with cars I have a desire to learn and have been helping friends recently which inspires me to take that roll. I have a trusted and experienced friend who is and agreed to help.
Any advice would be welcomed! Thank you!
