Has this ever happened to you? clattering on startup
I had a Mobil 1 oil change not too long ago.
When I started the car for the first time yesterday, the engine was making a clattering racket like I've never heard before. I let it warm up for a few moments and the clattering subsided to a fainter sound. Then I slowly pulled away and drove about a mile to my destination. There, it seemed it was completely gone.
Could this be caused by the synthetic oil settling completely into the oilpan? I thought synthetics did not do this (unless you let the car sit for a very long time). It doesn't seem like a week would be long enough to allow the oil to completely dry out from the pistons.
sometimes if it has been couple weeks or so, it does make this wierd sound like there is no oil in the engine, but it goes away completely after warmup. Unless the car is parked for two weeks at a atrech, I usually never experience this.
My Lexus ES300 (that does not see any action for months at a time) does a similar number on me, but not as noticable as the V8 e420.
Mine sits in an under covered parking lot for weeks sometimes (also due to travels) but fires up fine.....then again, we do have more moderate temperatures. Unlike you guys, I use an exotic brew, Selenia motoroil.
It sounds terrible.
I am in the northeast but this happens as much in the summer as in the winter.

ps-the steam cleaning also caused my #8 cylinder to misfire. Water had gotten into the cylinder and/or resister. The shop dried it out and that problem is gone too.

Regardless, let me add another element to this conversation: on Christmas eve morning, here I was in Maryland where the temp was about 19F and I got the most brief puff of blue smoke (accompanied by an initial clank noise)!?!?! I've never gotten that before! I could smell a touch of carbon as well. I have 145K on this farily well serviced engine, but this worried me.
What's up with that?
