    Check for split pipe or split tank?

    It is coming from the casing where the water pump is attached to

    Either The oil pump itself is leaking or more likely the rubber pipe that feeds it is split. its not uncommon on those as it contacts the casings in a few places

    It is literally comin from the compartment behind the water pump but underneath and theres a slight gap between the casing almost as if there should be a gasket or some sort of gasket paste there but the water pump 5mm hex heads are threaded so having a bit of trouble gettin into the water pump

    That is where the oil pump is located and if you mean the gap on the water pump drive casing it’s not a air tight seal/fit. It just houses the water pump drive wheel the gap is how it should be.. once you have that off and then the fly wheel you’ll get to your leak. You will need a fly wheel puller

    I managed to kick it over within ten mins and after 2 weeks of it standing still. I put a little bit of 2 stoke in and it just leaks straight out of the casing we were talking about i really do hope its just a split pipe. Im also replacing the water pump as it makes a horrible grinding like noise wen the engines warm and doesnt circulate coolant through the engine to cool it down my main problem was overheating.

    So my brother replaced the gasket on the head to see if that would help with the overheating as it had paste on and it needed changing and wen i got it home thats when the leak occured. Im thinkin he could of hit the oil pipe in some way in the whole process

    Your welcome. Worst case scenario or if you are not able to repair it you could just add the 2troke to the fuel tank. Premix

    you’ll need to sort that over heating problem first tho as you said

    It's not a major job or major money to whip the entire engine out and overhaul the lot really.
    And those scoots are becoming somewhat sort after in good condition.
    Would also be hugely beneficial to you as you would have all the usual (and up and coming) age related problems sorted.

    When I say overhauled, I mean new crank bearings and seals, all gaskets, barrel hone, new piston/rings/small end bearing, new fuel and oil pipes, new gearbox bearings and gaskets and oil.
    Parts cost wise, I reckon (without looking up costs) around £100. That's doing the job yourself.

    And while it's all apart, paint the engine cases and belt case.
    You'd have a brand new looking engine.
