I'm still sorting my 2 out this winter before spring comes along and have just an oil leak to still figure out. After running it a bit (first time in a few months), I have a small puddle of coolant in the spark plug valley. I think it is coming from one of the big bolt thinngys that is inbetween the plug hoels. I believe this "big bolt thinngy" is a plug to the water cavity. Anyone know the size of the allen wrench to try to remove this? All of this is after I cleaned everything up and it is recently coming off a head gasket change.
Any thoughts?

I think that is called a core plug? I had that happen to my n/a Mr2 a few years ago, but it was the oil core plug. No biggie, just findout the size and tighten it.

my 2 cents is remove the plug and clean the threads and reseal it with Toyota FIPG expensive but worth the money. that is what we do at work.

I plan on sealing it with ultra copper on the threads and top ridge. I also got a $15 hex bit socket set which includes the 17 and 14 size that is needed from ebay auction. This is much better then the $69 set from harbor freight!
