Hello Gents,

I'm in the process of replacing my timing belt.  Upon removal of the ignition coil (2001 MV6) for cylinders 1-3-5, I noticed that the metal underneath the coils were full of dried white powdered crust, and the ignition coil boots had orange stains so I'm guessing dexcool got in there somehow, evaporated, leaving the residue behind.  Anyone know what can cause this???  I can't see any other way coolant can get in that area unless it is coming from inside the valve covers?   I had oil leak in that same area years back due to a bad valve cover gasket.  My HBV did leak a few months back and I did replace it.. could that be the cause of this residue?

I was going to say HBV, only way I can think off, but the others will be along soon.

Classic evidence of water ingress from the scuttle

Re seal as per the guides, and being a lefthooker, pay particular attention to the join where the passenger side panel above the pollen filter meets the drivers half, as that is where the water is getting through, and draining straight onto the 135 coil pack...

The orange is rust staining from the coilpack itself. Turn it over and you'll see where it's rusting

Could possibly be from the hbv, but that is sited behind and below the cylinder head. So the far more likely cause is water from the scuttle. A hose in the windscreen while the bonnet is open will show the leaks.

Loose windscreen seals to scuttle. Pas side wiper spindle, and the scuttle join around the scuttle drain are prime suspects.

Is this what you meant...
