So I have never ever noticed my 420a smoke before today. I was sitting in the car while it was parked idling and noticed some smoke. Yep, it was me. Not real thick or anything, but enough to were I noticed. It was like a "thin" white smoke.

Now, like I said, I have never noticed this before. Now I saw no blue tint to it. It seemed more whitish. However, I checked the oil and saw no signs of coolant/oil mix. I will double check and change my coolant tomorrow.

Anyways, there is this tapping/clicking type sound I can hear every now and again. Having a hard time pinpointing it. Is there some type of emissions valve or something that could be going out on me and cause some smoke?

1 more thing. I did notice I was low on oil. Down to the minimum line. Could being low on oil cause some lifter sticking situation or anything like that.

Thanks a million guys! I am just stumped here being that I have NEVER noticed my car smoke before. Maybe do a compression check? What specs am I looking to be in?

Low oil will cause the lifter ticking.

Worn valve stem seals can cause you to smoke a bit.
