Greetings Trevor.

I have little knowledge of auto mechanics however, it could be a tapping in that it is more of a high-end sound vs. a low-end knocking...

If you made me guess, I'd call it Top-end tapping.

Thx.  chris

I've noticed a knocking sound from the engine compartment at cold start-up's. Gone in 1-2 seconds. Guessing is a engine lubrication problem. I run Mobile 1 at 5-7 thousand mile intervals and the 2012 ES350 has ~60,000 easy miles in the AZ. sunshine. 

Is this development bad on the mechanics? Should I be alarmed?

Any idea as to a cause and any potential fixes? Recommended oil aditives?

How's that for four questions? Thanks for any assistance.

Ladies & Gents, any input would be most welcome.

Aware of a good aftermarket product?

I have a broken Right Rear (outside) tail light. Is there an LED replacement that is nice, functional, and a good fit or is going back to OEM the best way to go?

Thanks for any input.
