Can you post a pic? You are not being very descriptive of where the leak is coming from. There is the big heater hose coming off the back of the head and a few other coolant lines that come off a hard pipe that wrap around the rear of the block.

I’m talking about the line off the back of the head that has a little play I don’t know if that normal or not since we’re new to 2JZs

The heater hose pipe coming off the rear of the head should not have any play.

That pipe is pressed in from the factory. I don't recall ever seeing one of those leak in all the years I've been working on 2JZ's. I would consult a machine shop or contact a reputable supra shop to see what they suggest.

You can kinda see there is a bit of coolant there but the hose clamp is as tight as can be, it’s a very slow leak because it take a coupe days for there’s to be drops on the ground but idk could be something I’m missing or don’t know

I have never seen that hard pipe come loose from the head, but I think anything is possible.

I guess you could try some kind of RTV or FIPG as a leak sealer, or even a product like JB Weld or similar, but I presume that the engine is in the car now and access to get around 100% of the pipe will be hard.

What a PITA :(
