Hi,
Can some please tell me the size of the drain plug for a 95 xjs and a 96 xj6 as I can't seem to find this information anywhwere.
Thank you

 

This one is mine, can't however say for sure it's the original part.
You'll also want a copper washer inside diameter 21 mm.

 

That looks right for OE.

Careful when tightening. Stripped threads can lead to a very exciting weekend!



This one came from the PO with a leaking plug.

LOL. I could easily take a picture of mine, because I've retapped my oil pan for a larger size... Was siliconed shut when I bought it.

 

Raook me 8 days of penitratimg oil ad heat

 

Can someone please tell me the thread sizes for the oil drain plug for the 95 xjs and 96 xj6

 

 

I can't even imagine what prompted them to use such a huge plug with such coarse threads in an aluminum pan with no structural requirements except to hold back some oil.

It is just comical.

 

from a mechanical viewpoint, the shear surface is the same for a coarse as for a fine thread (with a slight advantage for the fine thread), and a coarse thread is harder to cross thread.
Not such a bad choice after all, I'd say...

But I agree, most other oil pans I've seen have M14 or smaller as an oil drain plug.

 

You can drain 9 quarts of oil pretty fast with a 20mm hole but they should have used a 13mm hex head on the bolt to lessen the chance of over-torquing!!!!
