Hi All,
Not been on here for ages! 306 had been being far too reliable to be on here to be honest (no offence intended, i just haven't needed any of you!).
Long story short it stopped being reliable in a small way (stop solenoid) and by the time I next started it (three solenoids later) I got paranoid about every odd noise and thought I'd done some terrible damage to the engine.
Head came off - no damage to the head and none to the block or cylinders. Engine looks pretty much like new in the bottom end after 160000 miles. All good so far - probably should have left well alone! Valves out and I think I've found the/an issue - all the seats are pitted and worn. Cylinder head off to the machinist to be cleaned and pressure tested which it passed but unfortunately all four pre-chambers have cracks. They also recon all the valve guides and seats need replacement but I'm not convinced on that one.
So here's the questions:
1. Is there a specification for cracks in the pre-chambers/head that can be ignored as there is with VW IDI engines or do I need to change the chambers?
2. Does anyone know where to get pre-chambers for an XUD9TE?
TIA
