Bought this car second hand, they apparently put iridium spark plugs in, but i want to know if I should be concerned with the buildup and rusty appearance it's developed. For all I know this spark plug could be from 10 years ago.
Do I need to replace the plugs, and is that actually rust? Does this mean I have an issue with my head gasket?
Edit: Thanks guys! I'll be ordering some new plugs soon.
This is not good advice. I mean, it is if the bearings are guaranteed to fail. But it's like "I'm going to put new crank bearings because I drained the engine oil. It's only a few more bolts" disturbing the alignment of the tie rods and struts and ball joints. That will never go back together just right, probably end up cutting a rubber boot or two so in a month that ball joint is gona be trash too. Fuck might as well just turn a rotor and pad slap into a full front end rebuild. At that point. It's only 5 bolts.
