Bit of a leak

[DomP]

Ive discovered a very slight drip from my rebuilt 550, its definitely coming from one of the lower oil passage caps which you can see in the photo.  I wanted to replace the orings under them when I did the rebuild but they were seized so rather than round the cap off I left them, regretting it a bit now.  Any tips on removal other that butchery and a new cap?

Worst case scenario Dom is start the bike with the cover off and they should blow out at a fair rate of knots

Oh and a shit load of oil

Ask me how I know!

Obviously there's high risk on anything well stuck, of breaking, butchery etc .....

But .... these (or their type) https://www.ebay.co.uk/itm/305821836109 to flank drive it .... add to that a "hex to square" bit to fit in a drill with screwdriver clutch  .... you can gently rattle at it back and forth. They usually get something undone that feels impossible initially. 

You can keep ramping the torque up to see what you get. takes time, but various vibration frequency often gets them to "talk" to you.

I've got quite a few, what look like completely lost causes, out by this method.

Even if it doesn't move it, then you can move on to a more potent impact driver if you've got one.

Different plug Roo, these are the 10mm hex ones from underneath the crank.  Too soft to get a good purchase on

They can be $%%%^^ tight. I've only ever managed them with the six sided socket on a hand impact driver when the engine was out. Some may say that risks serious damage and not advise it though.

For that price and for a full set Nigel it's a no brainer not to try them using the method you described, absolutely nothing to lose and good addition to the tool box👍
