the search showed m16x1.5 thread btw it's not a pipe thread. the sender uses a gasket

what should i do to block it off, without spending $45 on a new one to use as a plug?

If you plug it, What will you be using for a Oil Pressure gauge....?

You could always use a metric bolt. Just grab a M16mm x 1.50 bolt, the sender is ~ 2cm long so you would probably have to cut the bolt length down to fit. There needs to be a seal on it, the factory uses a aluminum washer on the sender but you could also use a copper washer (think oil drain plug gasket)

sweet. i ordered 2 (on accident) oil pan covers (located next to the oil filer) i planned on drilling it out and using my autometer sender there.

just like the sticky says to do.

by the way, this is going in a 69 camaro

here are some pics of the oil bypass cover next to my autocraft oil filter adaptor.

I believe you can get drain plugs this size from the local autoparts store.

For my motor I bought an adapter to go from the M16x1.5 to a standard oil sender thread and mounted it in the LS1 location. Seemed simple enough if you have the room.

It i s a common oil drain plug size - any decent auto parts store will have what you need.
