Hey guys,

Another welch plug gave it away couple of days ago.
This is not long after I did the last one which was just over seven months ago.
I'm thinking doing all the welch plugs on exhaust side now, just to be safe.
This one will be a bit of a PITA, 'cos both the exhaust manifold and engine mount gets in the way of doing it.
But, I'm sure I can manage it without having to pull the exhaust manifold out to create access room.

I'm bit puzzled by the colour of the fluff on the welch plug though.

The coolant I put last time was anti corrosion stuff(but not antifreeze) with distilled water.

So, what creates the yellow colour, in addition to the green colour?

yep generally speaking when one goes the others will follow soon, so best to change the lot
