I happen to have my data logger on for live data when I turned the car on and had a shake/engine rattle this am. 202000 miles currently part of EGR cleaned front piping and complete cleaning of the intake manifold along with spark plugs replaced 199000. I am the second owner I bought it from auction local trade in. Possible small decrease in coolant hard to say. I can post the data but there are 320+ data points. Just need you all to pick which ones you want to see then I will post the data at the time of the shake thank you.
I understand head gasket is an issue along with egr etc…But I am unaware of some catching the engine rattle with data. This is more of the ability of seeing the beginning of the issue at hand. I have seen EGR system is the cause of the issue or like you said head gasket fails and leaks coolant. Just seeing if people want to see the continuous health of the engine as it declines.
