Hey all,
I'm getting the weirdest sound and I'm nervous it's something really bad.
When my truck ('01 LT w/5.3L V8) has been sitting for a few days, and possibly after one cold night, I get a strange whooshing/grinding/rubbing noise on startup from the engine area. If I immediately shutdown the engine and then restart, no sound - everything then sounds good. Otherwise the truck runs great. It sounds as if something is sticking, but I'm really hoping it's something with the starter and not with the engine internals.
The only other clue I can give is that about the same time I started getting some valve noise for the first 3 to 5 seconds of driving the vehicle if I don't let the engine warmup for a minute or so first.
Thanks for any help.
