Well this is a timely thread - Minnie has now got the same incontinence problem
Motor was fully rebuilt and has done about 2,500 miles now. I first noticed a slight weep from the middle plug on the front after a run on a pretty warm day. Temp never got over about 95 as I was keeping a close eye on it. After that run, I noticed the green engine paint had come off as well as the red stag that was on the outside of the plug. Mainly around the edges of the plug. Other 2 are fine and paint still like new.
As it's not leaking much, I haven't worried about it but did a run of a few hours last weekend and while parked overnight, I noticed about maybe a tablespoon or so of coolant on the drip tray and some coolant also on the block below the centre plug.
The plug itself still has quite a noticeable "curve" shape to it, much like a new one I suppose (I didn't fit them so not sure).
I've read the info about giving the plug a good whack but before doing that, I'd like to check if:
1/. It would be best to pull the old one out and start again?
2/. If I try giving the current one a hit as described, what can go wrong? Can I hit it too hard or will I break whatever seal the stag has and the leak will be worse?
I've never played with these before so would be getting an experienced Mini bloke to put a new one in if that's the best option.
Thanks Rocky
