Monday morning is D Day, it's in the garage & the mechanic is gonna have a proper take apart look. We have some contenders for the water leak.
Go on, place your bets.
a. Timing chain/water pump gasket - nice & cheap to fix.
b. Core plug behind the alternator mounting brackets - reasonably easy & cheap to fix.
c. Leaking water pump bearing - more expensive due to new pump required.
d. Inlet manifold gasket could be leaking water (water cooled??) - Bit harder with a lot of fiddling getting dearer.
e. A leaking cylinder head gasket requiring removal of the head, skimming & refitting. Also, as your in there, you may as well get the other head done too. I'm guessing at the thick end of £500 to do the job right?
I know where my money is going? Yours?
Not to mention the leaking front crankshaft oilseal ffs.
Come on, place your bets...............
