as the title says im leaking coolant out the back of my engine near the firewall it only does it when i turn the car off and it just pours out... Now im thinking that this is coming out of one of the heater lines, but im unsure.. anyone know what it could be and how hard will it be to fix myself???

Any help would be great, cheers Mike

Very common problem with skylines and nissan in general.. It is most likely the metal pipe which attached to the block (its not running out of it just bolted to it) you will need it on a hoist and a damn long extension once you get the starter out.

FYI Cold welds will not work.. Welds will but the part was only $50 from nissan for my R34 so cheap as.

whats it called just so i can tell my mechanic... cheers

Heater pipe is a non technical term which refers to several of them I guess... however it only had a part number goto nissan and get the engine diagram for that part of the engine and check it out.. Thats what I did.

Then order the part.. Or remove/order/replace.

Same thing happened to me a while back. It would piss out one the engine was turned off.

My leak was a hose that connected to the metal tube from the turbo water line. Hot coolant from turbos expanded more once engine shut down and found the easiest way out.

Got under car and moved starter motor. With one hand I managed to replace the pipe (crap job to do), took me 5 hours.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
