Just removed the spark plugs from my car, is this usual wear? And also one of the ignition coil is noticeably covered with rust as compared to the other 3. The car also produces some white smoke when engine already warms up, guessing its a blown head gasket. :/

Anyways, do post your thoughts on these pictures.

No. That is not normal. Looks like you do have a head gasket issue. Here is a guide that will help prove that out:

You will want to test the head gasket after the engine is warm.

As for the plugs it looks like a couple of issues. They appear to be overheated and have oil fouling. This is not uncommon for a head gasket issue.

If the head gasket is blown then after you repair it, you would want to run a compression check not only to test the new gasket but make sure you didn't develop another issue as well. Clearly when the head is off you want to put a straight edge on it and make sure it is not warped.

Let us know what questions you have and we can go from there.
