Can we find password stored area or lines in wallet.dat file.

[Muhammed Zakir]

No.

From https://en.bitcoin.it/wiki/Wallet:

The original Bitcoin client stores private key information in a file named wallet.dat following the so called "bitkeys" format.
It contains:
  • keypairs for each of your addresses
  • transactions done from/to your addresses user preferences
  • default key
  • reserve keys
  • accounts
  • a version number
  • Key pool
  • Since 0.3.21: information about the current best chain,
    to be able to rescan automatically when restoring from a backup.

i find it odd that you cant.

some recovery services ask you to dump your hash from the wallet and the hash itself within holds the passphrase.

as mentioned by Dave here: https://walletrecoveryservices.com/limited/

if its not remotely possible, why would he ask for this?

unless OP is referring to readable ascii text.

The keys are encrypted with a randomly generated master key and the master key is encrypted with the passphrase(derived after putting it through some algorithm) that the user has provided. The service can bruteforce the master key and thus get the passphrase. The address part is probably just to verify that the passphrase is correct.

The wallet.dat file is a Berkeley DB file, not a text file. There is basically no human readable text in it (except maybe for comments) and is in whatever binary format BDB uses for its database. This means that unless you have something which can read BDB files, you aren't going to be able to find anything of use. It's really just a binary blob.
