Car leaking gas? Or tons of oil.. really not sure. Sign In

I was fixing an oil leak and replaced my oil pressure sensor and switch. Noticing the oil leak was gone I was going to run the car and noticed a weird noise when laying down under the door.
Here’s a picture of where I am talking about;

As you can see on the picture, the metal circular piece is what I’m talking about. I had a friend start up the car as I watched and I heard a noise that I can’t really explain but when I looked at where the noise was coming from I saw the circular metal piece spewing out something. I have very high suspicion that it was fuel rather than oil. It has this clear look not like oil and it was spewing from the edges of the metal pieces. Need some help with this one because quite honestly I don’t even know what I am looking at.

The picture is an exhaust pipe. It should be very easy to tell if it's gasoline or not. Smell alone should tell you. This could be very simply a pipe positioned beneath the AC condensation drain and what you are seeing is just condensation from the air conditioner.

The air conditioner actually isn’t working, idk why it just isn’t even turned on when I get in the car/ it doesn’t blow. This is also off of a cold start so it definitely can’t be water coming off. It was for sure gas, I actually accidentally got my hair on it and when I went in the house to clean it off I had the smell of gasoline that I couldn’t get rid of so I believe it’s definitely gas.

Computer in SLOW MODE but saw that. Looks like oil to my eyes quite likely from the oil leak you were fixing I do think if that's the area NOT forward of it that's it.
The sound is escapes me it should just burn off slowly with a drive?? If worried spray it clean (everything cool/cold) with carb or brake cleaner (toss those paper towels or burn them) be done with it faster.
Water from A/C can give you a sizzle on some vehicles but would before this too IMO you just weren't paying too much attention. If quite humid can be a lot of water.
Once again if you can watch it if annoying and is just that some vehicles use a rubber elbow, some with a closed end like a Whoopie Cushion might misdirect condensate (proper name of that water) to hit hot pipes? IDK - try to divert it without harm I guess if bothering you,

Yes I went back to it and maybe it just had oil on it earlier because it was just spraying a tiny bit of water like you had mentioned. I caught the noise on video I just don’t know how to share it, it’s a grinding noise coming from under the car when the car is started. It’s so loud it sounds bad when I start it— it has never had this problem before. 1991 corvette 131k

This is also where it was leaking oil.. I found a part where there is now screw and in this image you can see what I’m talking about (this is separate from the noise mentioned above).

Just need some help finding out why there’s not a screw in there or why it’s leaking small amounts of oil it leaks whenever the car starts up. It is located inbetween the transmission pan and the oil drain plug

That's the "dust shield" for a torque converter looking - right? Now time to put a drop on white paper to identify it. Match drops from oil dipstick and trans dipstick also.
At least know which I think it's hard for engine oil to overwhelm that from a pressure switch above maybe from a rear main.
Wasn't this a real Chevy engine? Small block all iron vintage some dampness or leak was mandatory or burn out seals but not active. Front pump of trans in vintage also shouldn't drip but be damp with oil. That's how seals stay from burning up right away for ages of pumps and engines of all sorts.


You (on the maybe list) might have poked around for a long time with this engine/vehicle and now both warmer out and if you gave it a good run even normal oil seeps the cake up will make smoke, odor if you work them hard after quite a while of slow and short runs.
Smile my own will don't go over 30 much and might not be used every week then only 10 miles so purposely burn that off (all older stuff) if time to take a long route at highway speeds unseen to you (just trust me) exhaust can glow slightly up front if caught really working it hard.
It NOW matters that should not be there that much if active another fix is in order so this game may not be over yet,
