Or...... someone's re-drilled a manifold stud hole, and went a little deep.

How does that green stuff feel to the touch . . . . oily / greasy or wet ??
BTW . . . . . great pics. Hope the excess grease is just leftover from the power gun . . . the good guys wipe it clean after. At least better than none at all.
Any hints on locating that welsh plug without destroying my soft/supple hands[/QUOTE] . Using the soft supple/brain works fine
Most of the fluid will be running down from the plug out of view as its behind the exhaust manifold gasket , you will just have to fix it , at least you shouldn't break any exhaust studs if the gasket was done recently.
Not sure why someone would spray paint the oil cooler though, and as someone mentioned, refit the oil switch wire
Hi, can you tell me what's a Welsh plug? Good pictures btw.
First up it should be welch .. I think mainly because it's not from Wales!
Core plug is another term.
When they make the casting, they need to allow for access holes from where the metal is poured into the cast and to create the coolant galleries too.
So inside the engine block are empty spaces where coolant flows to keep the engine cool.
The welch, or core plugs are literally that .. a plug to seal those access holes. They're usually pressed in, but as seen earlier in this thread, they also make them screw in too.
They can rust, and cause leaks too.

Hey BrightBlue,
I'm a newcastle local and happy to lend a hand/advice if you like? Also have a nanocom if you need faults cleared or testing done.
Also noticed there appears to be exhaust putty on #5 so might still have a warped manifold? When you have the manifold off to do the plug run a straight edge over it.
Might need machining flat? I can recommend a place to ceramic coat if you need or want it done?
Cheers Craig
