I recently bought a 1990 Honda Accord DX and the previous owner said that it was leaking oil from the oil sensor. I wanted to know what it is actually called (I am guessing it is called the oil sending unit, or something like that) and where is it located on the engine so I can replace it myself?

I read that I would need Hondbond for the threads. Do you know if it is cheap to buy from the dealer, or are there alternatives to Hondabond that work the same as Hondabond?

Thanks

 

it is located directly above Oil Filter. Just use some Teflon tape on treads

 

Thank you for the help and the pictures make it a lot easier.
