    On my new 2000 Zx2 I pulled the coil wires off and noticed two of the spark plug wells (on passanger side) have some coolant/water in them. Any I idea whats causing this? This will be the second time I have got the coolant out of the well and no I have not washed the engine bay so its not tap water.

    I just performed a pressure test on cooling system after I serviced the T-housing and flushing the system and it passed. The engine looks like its had a valve cover gasket sometime recent because the gasket is clean looking and blue in color gasket. I uploaded a couple pitures for you guys. And no its not mixing with the oil andno its not over heating.

    Are you sure it’s not oil? I don’t see how coolant can get in there.

    Could just be condensation or something. Not sure how coolant could get in there.

    Its not deep water in the wells like in that video and the car passed a coolant pressure check so highly doubt its a cracked head but I will check it again in a week and see if water comes back as there is no rain in the forcast for this upcoming week. It has rained for 3 days straight recently as I live in the Midwest. Car does not appear to be overheating.

    (Remember my tempature gauge on dash doesnt work but no water boiling)

    I know on some later model Fords this can mean a leaking intake manifold gasket not sure on the design of the 2.0 DOHC water jackets

    Just an idea since I was recently driving in the heavy rain on the Hwy do you think water is getting past the hood seals or spraying up in the engine bay and landing up on the valve cover than leaking down in the spark plug wells?

    That’s possible I guess.

    Just a 2 day update after driving the zx2. Weather is clear and no more water in spark plug wells. I will report back this weekend.

    There is a gasket that goes on the firewall in front of the wiper cowl. make sure it's there.
    There is also a piece of rubber that goes on top of the radiator. I don't think it's that important but make sure it's there too just in case.

    Good idea. If they are there do you have any ideas on how to remedy the problem? Like a diffrent style valve cover that is designed differently?

    Yes the rubber boots snap into place and cover the spark plug hole but obviously its not a water tight seal. Does anyone else have issues with this. Still no water currently in the spark plug holes but I bet if it rains hard again the rain water will find its way in the spark plug well.

    Normal hot/cold cycles may be responsible for drawing in air/water past the weak seals on those boots. Crap ton of dielectric grease might be worth trying.

    Maybe an equivalent diameter rubber o-ring?

    The 2nd-Gen 'scort's wells are angled and have a drain hole. Is there a drain hole at all for the ZX2?

    Seems about impossible to find one of those ZX2 engine covers I linked to. Wonder what would be a good material to make one out of...

    I thought about fabercating a piece of metal similar to the 1998 ZX2 valecover that covers the spark plug boots. I guess a O-ring could work to. Even a plastic engine cover off anothe style of engine might work lol.

    Some ZX2's had a cover that went over the wires. You May be able to find that in a junkyard or on ebay

    Might be able to measure and grab just about any plastic one that is wide enough from any junkyard engine and cut it to size? Can't recall ever noticing a junkyard engine that still had one at the local U-Pull though.
