Knocking on startup!?
I've seen other posts about similar experiences, but I wanted to get opinions on mine.
The car has been sitting for the winter, but I usually start it up and run it to operating temp. once a week. Well, the car sat for about 2 weeks and when I finally started it, a lifter or something was clearly knocking very loudly for about 1.5 seconds, then smoothed out to a regular idle. This also happened last time I changed the oil. Is this common on this engine with this viscosity synthetic oil? It was obviously caused by a lack of oil to the top of the engine. Once the oil made it back up there, things were quiet. Thanks in advance for your replies.
EDIT: Ok, I did find an almost exact post to mine; however, it doesn't really give a definite suggestion. The answers ranged from the issue being normal to this being the beginning of a common lifter replacement problem. The car has 13k on the clock.
