The oil drain plug on my 2004, 5.3 with 210,000 miles on it, is shot. I got a new one to put in at the next oil change, but have begun to think that I probably need to get a tap to run thru the hole to make sure the threads are OK. What size is the drain plug hole?

you have the new plug right ???

I've seen some that are a standard size and are self-tapping. I think you can get them at any auto parts store, especially the big ones like Auto Zone, O'Reilly's, Pep Boys, etc.

I forgot to add that the one's I'm talking about actually have a brass plug within a steel casing. So, once it self-taps, that part stays in place and is "permanent". To drain the oil you'll unscrew the brass plug from within the steel one.

BUT....I'd go with a Ford solution before aftermarket.

I got a Ford one. They had to order it. Looks like our trucks are being obsoleted. 14X1.5 looks right. Just wanted to be sure.
