Hey guys i have a big problem and not sure where to start, my 1jz started having a coolant leak from thealuminium piping that is behind the block right up against the firewall kind of underneath the intake manifold. I looked up the diagram here ( http://www.lextech.org/documents/Fig%2016-03.pdf )...and thinking maybe its 16278 but not completely sure but it feels like its shaped like that....feels like someone put jb weld on it and just tried to quick fix it but now its cracking and leaking pretty bad. anyone able to confirm what my problem might be? with the position of everything i might have to take out the motor crossing my fingers though.


some added notes: every time the car gets warm and i shut it off that is when it starts leaking and i have to fill the radiator back up each time just to make sure i don't overheat, and even the overflow bottle doesn't hold water and i dont want to keep driving it with this problem.

 

if it's that pipe it's made of stainless. It's also something I can't think of getting off without pulling the intake and turbo/s.. Can you put it on a lift somewhere and get a better look at it from underneath?

 

That's what I was going to suggest. Those lines should be pretty easy to find. I am sure someone on here has it. Keep us posted, in what you find out.

 

yea i am going to put it on a lift as soon as possible, but i had it on jack stands today couldn't really see much only could feel just really hoping i wont have to take the engine out haha but yea i does wrap about the whole engine from the intake side to the turbo's just don't know the technical name for those pipes or where to buy them.

 

will do i will try and do some more research on it also see what i find out, i cant be the only one that had this problem...or maybe i am haha

 

i finally found a pic with that pipe! its been a while but yes its still leaking but in this pic its that stainless steel pipe that curls up on the right that is leaking, what is the exact name or part number for this because thats the lil bastard thats leaking

 

should be the for the heater?
