Engine coolant in with spark plugs - what could it be?
I've got a 2005 Ford Focus. A few weeks ago it started juddering and the engine light was flicking intermittently. My mechanic found lots of brown, horrid water in with the spark plugs, which were very rusty. He replaced those and the HT leads, which seemed to solve the problem.
A week later it started juddering again. This time there was pink liquid in with the spark plugs which was identified, using a Hydrometer, as engine coolant. He's identified it as a cracked head, based on crystallization he's found and a faint line on the head. I'm after second opinions as it's looking incredibly pricey to repair.

Standard problem with the 1.6 petrol engine in the 2004-2008 Focus. If the car is not used very much and the engine does not regularly get hot enough, water collects in the spark plug channel between the cam covers. (The "horrid" brown water.) Eventually that water rots out a core plug and coolant starts to leak. (The "pink" water.).

My 1999 Toyota MR2 seems to be rattling/pinking under acceleration. I’ve checked the timing and its spot on at 10’ BTDC. Can you suggest any other issues that could be causing it? It was recently serviced...
Every few weeks I have to take the same spark plug out to clean oil off of it because it starts misfiring. Could you please tell me what the problem may be?
