Hi, I found one of my spark plug soaking with oil, when I changing the spark plug. I think it might be the spark plug hole gasket need to replace. I don't have any oil leaking around the engine. It is just some rough idle at start off to give misfire code.
When I look at You Tube on how to change the valve cover gasket, someone comment about replace the timing chain guide. Is it something in regular maintenance? Is so, what else I need to replace, since I open the cover already.
I will also change the thermostat as well, getting the engine code that it keep long time to get engine to working temperature. I have 104k miles in 9 years, it should be time to change.
Thanks in advance.
