WTF is this?

I've read that this is either a 'freeze plug' of some sort, and also heard that the hole is there for when the pump is on its way out....anyone else know? Either way, its leaking and is a huge pain in my ass.

Man, you don't want a hole in your water pump. Better plug that up with some JB Weld!

No, seriously, it's called a weep hole. If you ever see water coming from that, the seal in your waterpump has died, and you need a new water pump. It's normal, as long as it stays dry!

Dammit, I guess that means my seal is shot then. Its not a high pressure piss out of it or anything, just a steady weak stream of drops.

If its leaking through there u need to change it, time to buy a new one, U have officially found one of two things that usually goes out on the 1J, water pump or twins. I have gone through both

That is where my water pump is leaking from as well. I have gone through all 3 of the major 1JZ problems. Replaced the water pump, twins and the ecu.

A big thanks to all of you for helping me out!

I was lucky to source a used 1j pump locally for $45! I really want to keep the hydrofan, so I looked everywhere I could.

Haven't had to deal w/ the ecu yet, and hopefully never, cuz I have a hotrodded Blitz. 2 yrs ago I had an oil seal go out on the front twin, but luckily I was planning on an upgrade already and ended up throwing these babies on.
