So the first thing I noticed on our newly acquired 99 Firebird was the engine oil was milky which can mean moisture or other fluids mixed in, the filler cap was dirty and smelled and had what looked like water droplets on the inside. Same goes for that rubber? elbow piece that you pour the oil into when adding. Cleaned both and changed the oil, didnt look that bad when it all came out but definitely wasnt changed in a while. Now the elbow seems like its loose i can turn it clockwise and it seems like it comes to a stop but still seems loose. Im hoping this is the cause for the moisture and not something serious like a head gasket etc but now that Ive changed the oil Id like to get it fixed asap. Can this piece be purchased? I dont want to twist it to find out in case it falls out or breaks leaving a nice open engine, never seen anything like this, with jeeps the cap screwed right into top of engine. I know I cant be the only one with this issue can anyone offer advice?

Most oil caps and valvecovers will look like that becasue they do not get as hot as the internals of the engine, and therefore do not evaporate the condensation. Being farthest away and real thin, they create condensation on the inside. The worst is when there is a long "oil fill tube". My old S-10 was bad for that. Fill tube would look horrible, but oil was fine. I just clean them every couple of oil changes. As long as the oil on the dipstick isn't milky, your fine.
