engine wear - ZR-1 Net Registry Forums

Yesterday before taking my car out for a spin I started it and let her run for a few minutes to warm everything up. Backed it out of the garage and thought I heard a slight knock. Shut the car off and checked the engine oil which I do religiously. Upon inspection it was low. Very low. I also saw what I thought at first glance was bubbles but upon further inspection was shiny bits of metal. Put a magnet to it, it's not magnetic. Now I know the engine is going to wear and there will be metal in the oil but enough that it shows up on the dipstick? After I let it sit again for a few hours and looked at it when I pulled the dipstick the oil barely reads up the dipstick. Today I'm going to drain the oil pull a sample, refill the oil run it for a bit then drain resample and refill again with fresh oil. There's only 30k miles on the engine I'd find it very hard to believe the engine is coming apart already. Maybe I'm just freaking out as I've been known to do with my cars. Also it seems to have excessive crank case pressure as after everytime I drive her I need to push the dipstick back in to the tube. It will get blown out maybe a 1/4". Any ideas what could cause that?
