Default o-ring

5/32" x 1/16" buna N oring stretched over the oil return bolt stops a pesky leak at the drain tube,works with the stock shouldered bolt as well.

1/2 x 1/16 buna N oring works great as an oil drain plug gasket.

you can get them at a hydraulic shop or a good auto parts house,get buna N,it resists tearing.as an added benefit the oring compresses and helps to lock the assembly.

Good tips. I also put an "o" ring on the timing pin to prevent seepage. Added bonus you can unscrew it by hand when needed. Sorry, I don't remember the size.

Figure you fix all the little leaks and maybe it will stay dry..for awhile.Used the copper washers,still leaked,you don't need Berts for copper washers btw..the orings conform to any deviation in the hole,squeeze in and seal.

Didn't the original bolt have a larger shoulder below the head?

I could maybe understand using an O ring under the cup on the oil overflow pipe where it attaches to the side cover and block, but not under the bolt. How are you going to get enough crush on the gaskets to seal? Big globes of sealer? I would never use an O ring under the oil drain bolt, hard rubber type gasket maybe, but not an O ring. The oil drain plug is not made to use an O ring, if it were it would have a channel for it to sit in. flat on flat, to much chance of distortion of the O ring and something nasty happening.

the 5/32 16th stretches over the 5/16ths bolt and it squeezes to seal,same with the drainplug, its stretched tight,and compresses when tightened..it works for me,if you don't like it.. dont do it.

Need a drain plug gasket, in a pinch, go to a Land Rover dealer or an independent foreign parts house. Ask for a Discovery Series One gasket. Identical. And I would never use an o ring in that application unless the under side or the hex is faced in a lathe with a radius to fit the cross section of the rubber ring.

When an o ring is used in a static application,where the o ring is pressed against a machined face,like an OFS fitting I agree,how I'm using it is different.Stretching the ring tightly over the fastener.essentially reducing the cross section and elasticity by doing so..the remaining cross section is crushed when torquing the bolt,without squeeze out.
