the oil pan pic reminds me of a delivery van at work. driver started it, said it was making a noise, checked oil and there was none showing on the dip stick. call was made to change oil. mech "tried" to pull the plug and it was stuck. it unthreaded, but it kept getting sucked back. finially got it out and nothing but molasses inside. they ran enough of something thru it to clean it out, change the oil and filter and then got the engine warranted...
