Check all the coolant hoses and connectors.  The connectors have been known to be a bit weak and prone to fail

Geese: I was told car has 3 month/5000km warranty at time of purchase, its been 7 weeks/3700km now.


Forget their "warranty". CGA applies - it offers guarantees that far exceed their hollow promises. Goods must be be of acceptable quality and durable.

Geese: I contacted dealer about the issue and was told... "It sounds like your car needs a tune. This is a maintenance issue."


Not in 7 weeks. They're trying to fob you off. Make sure you've got written or audio confirmation of their rejection of your offer of the opportunity for them to rectify the problem, then get it sorted yourself and claim the cost back through the Disputes Tribunal.

Aredwood: Yes coolant could easily leak into just 1 spark plug cavity.


No. There are no coolant seals to leak in there.

Geese: So the question now is, could coolant (orange Ford coolant) be leaking somewhere and pooling in the #3 spark plug cavity? Or is it co-incidence it looks orange - and may actually have been caused by the engine being steam cleaned 7 weeks ago? The spark plug cover is pretty well o-ringed with good gasket, and would surprise me that the water would have only got in to one spark plug cavity.


Water can get into the plug wells when engines are stupidly pressure washed. Along with cleaning concrete (a pet peeve of mine), it's one of the dumbest thing anyone can actually use a pressure washer for.

How did you determine it was actually coolant? Smell?

The first thing I did after picking up the car was do a 800km drive home, so I'm surprised the heat didn't drive the water off. Since then its done 35km trips each way to work mainly - maybe it was chocka with water but the cause of the issue was rust corrosion buildup over last 7 weeks rather than the pooled water itself?

I'm not a mechanic, but my understanding being the rocker cover if there was a leak, it could only be oil. The flaky crusty stuff must just coincidentally be orangy/yellow.

Without seeing what you saw it is hard to say if the issue is coolant loss or some sort of cleaning product.

A rocker cover can only really leak oil, not coolant om these cars, there may be a coolant feed to the intake, but I no longer have access to a falcon to check.

Generally the rocker cover area wouldn't get hot enough to vaporise the water so it can sit in there for a long time, Commodore V8's have an issue where when the engine is washed down water can get into the valley cover where the knock sensors sit, they then rust and stop working correctly, again not hot enough to get rid of the water so it does sit there.

If you don't have a repeat of the issue and you aren't loosing coolant it would seem to be a one off issue when the dealer steam cleaned the engine.

I would however send an e-mail identifying the issue, highlight the response that they did not want to inspect the vehicle and if this comes up later and you need to claim on them present the facts.

I had my alternator crap out soon after getting my Commodore, I have to say the dealer was very good to deal with and came to an arrangement quickly, they were obligated to replace the part, this meant it could have been second have, I wanted brand new part, a deal was struck and they gave me the equivalent dollars in cash that the repair would have cost, plus some running around money and allowed me to have a new part fitted.

clean it out, drive it for a while, check it again.  If anything was leaking, it'll be wet again.  If not it was just from the cleaning and you've nothing to worry about :)

Once water gets/is forced in under the plug covers / coils it can't really evaporate back out.  Have seen this happen on other cars with deep plug wells many times after an under-bonnet wash.

The water won't quickly dissipate because of the fact it's trapped under the seal. It'll remain a very humid atmosphere for quite awhile. As the engine is run the contents of the plug well will heat and expand, forcing some moist air out past the seal. When the engine cools, some ambient, and hopefully drier, air will replace that. But it's pretty miniscule and a slow process over many cycles. I have seen vented plug caps to release the pressure and break the vacuum caused by the cooling air.

Like... rust... haha

And yes, oil is usually the only liquid with an immediate access path to the plug wells via a leaking rocker cover gasket.

Hot coolant has a quite distinctive, sweet smell - it should still be noticeable even in a recently cleaned engine bay covered with shiny groomer products.
