Oil Pan Plug - what size hex head wrench?

[jack Bacon]

My Series I engine requires a hex head wrench for the oil drain plug removal.
It looks to be 1/2" or a hair over. What is the correct size? Thanks for the help!

I had one that was 9/16.

Not sure if these are stock though since I see far more non "hex" oil plugs.

The question is once I get the hex key plug out can I substitute a standard drain plug or need a special size.

Sure, I think the transmission drain plugs are the same (if you have a spare trans sitting round).

Jack - if it's the original one then a 1/2 " allen wrench will work.

Oil Pan Plug ; What size hex head?

Hi Scott,

Thanks a lot for the help. Will be doing a lot of upgrades on my car this winter so I'm sure I'll have alot of questions and be learning a lot.

Best regards,

The engine is a Series I and it turns out that 9/16" was the correct size.

Hi Guys,

So the correct size should be 9/16" thread with a hex head (socket) or cap screw (1/2" Allen key)? My Alpine (aluminium sump) has the cap screw as the drain plug. Which type of bolt head should it be ?

Thanks, Robin.
