As I mentioned before (last year), I can relate to the oil suction tube melting inside the dip stick tube (I have the t-shirt). Now I am using a metal tube (it came with Pela pump) and waiting for the engine to cool off enough. The process takes longer, but you can skip removing the dip stick tube, which is an interesting process by itself (access to the bolts is somewhat restricted).

I suck it out with a dip tube in the dipstick hole. So for sampling it is the same process with a different sucker pump designed for sucking the sample into a sample bottle. On my Grand Prix the dipstick tube was too long and narrow. The first time I tried to suck a sample from the hot engine I melted the sample tube inside the dipstick tube. Oops. Recovery involved unbolting and removing the dipstick tube from the engine and using a coat hanger to push out the cooled plug of plastic. After that I had to pull the drain plug and then slip a sample bottle into the stream. Much messier. Josh
