Is there supposed to be summat in that hole?!

[rojbarker]

Afternoon,

I was under my disco last night and I noticed that between the crank pulley and the sump, there's a threaded hole in the bottom of the timing case (water pump housing?) It's directly underneath, on the very bottom of the housing. There's a little bit of oil around it but nothing major - is ther 'sposed to be a bolt or something in it?

I've put a diagram on but will try and take a proper photo if I'm not making any sense.

When u go in deep water 0.5 metre u screw a Wading Plug into the hole. At other times leave it out.

Really? Thanks for that! Why is it normally open then?

I've only just bought the Disco and was a bit concerned there was something important missing!

If an oil seal goes then u will have a indication.

nickh75 said that also, I think!

It's because oil seals do weep and if one was to leak badly you would rarther it comming out than build up and degrade your timing belt and have a wrecked engine on your hands. you also have one in your bellhousing (behind the sump) depending on what gearbox you have. Jai

That makes sense then, cheers for the info.
