    So my 66 Coronet Hemi tribute has a 492 Hemi with a World block and Moroso deep sump oil pan (sticks down ever so much lower than the K-member skid plate). Took out the dipstick to check the oil, was low, looked like just a bit was showing on the stick. Put in a quart. Can't get the dipstick back in, it's hung up on something, goes in about 2/3 and gets stuck. Decided to change the oil, emptied about 5 1/2 quarts our of the pan, so it was low if you believe the stick. Put back in 6 quarts. Finally got the dipstick to go all the way in, pull out, but no oil shows on the stick. Talked to the guys at Mancini's, bought a hemi dipstick. It's WAY different than the one from the car, see pics, the Mancini is on the top. It only sticks down from the flange about 3 1/2 inches, vs. the original one about 10. WTF is going on? When I get the original one to go in (with a bit of force), it shows no oil on it. But there is 6 quarts in the engine, and nothing on the floor. I am at a loss. Any help please?

    Fairly common for a dipstick to get hung up partway down. Just takes a few attempts. If you have a real deep sump pan, the oil is going to be below where a normal pan oil level would be, therefore it doesn't show on the dipstick. The Mancini stick sure doesn't look right, maybe for a Gen 3 Hemi?

    Edit: The deep sump pan also is likely designed for a larger oil capacity, maybe 8 or even 10 quarts, which is why it's deeper.

      When I got the car, I checked the oil, and there was some on the bottom tip of the dipstick. Now after 6 quarts in the oil change, nothing. If I put in another quart, and there is something weird going on that the dipstick is not catching, how will I know without the dipstick I have over filled? If I know there is 6 quarts in it, running the engine should not make any damage, correct?

      Post a picture of the pan.... How deep is the sump from the pan gasket to the bottom of the sump? If it's a 8 or 10 qt pan 6 qts isn't gonna show...

      Depending on the pan shape the stick may hit the pan above the oil level. Then it just slides across the pan bottom. Mine did on my Charlies pan. The tube was relocated to the pan itself.

      When I bought my car, there was no dipstick. A fumoto valve and a piece of clear tubing (plus a little physics) gives me an accurate oil level.

      Looks like a Milodon 7qt pan or something similar.

      We still don't know what pan the OP has. A "deep" pan will likely not show on the dipstick with only 6 quarts in it. If it's a 8 qt pan, it will be 2 quarts low.

      I'd get dipstick and have the right or known amount of oil in pan. Put in 5qts mark the stick, add a qt mark the stick add a qt mark the. stick etc..

      6 quarts are in it, no show on the dipstick. The pan bottom is just below the K-member skid plate, i.e. really the skid plate wouldn't prevent a catastrophe from happening. Something that deep have more than 6 quarts?

      YES, that's the purpose of a DEEP PAN.
