The Dissapearing Water Trick- Rb26 Consuming Water.

[Mohsen]

hey guys
have an RB26 with a 1.3mm ACL head gasket.
car has been using water for a while, doesnt get hot, just seems to keep taking the water somewhere.
absolutely no leaks on this thing at all, which leads me to think that its busted a head gasket, which is also why it wanted to detonate when we pushed it for more boost..

going to pressure test it and comp test it tonight.

You may be right. The water has to go somewhere. Since you can't see an external leak and haven't mentioned milky oil, it sounds like its getting into a cylinder and being combusted. Any traces of white smoke coming out the back? Hopefully the pressure and comp test reveal something.

Farken Nissan motors and their dissapearing coolant tricks. I've had the displeasure with dealing with a similar issue in the past. Good luck. Let us know if the testing reveals anything.

Just a little smoke on start up, might even be the head lifting under boost.

Ordered some new arp head bolts anyway. Waiting for my mate to come around with his equipment.

ok started pulling shit off to pull the motor out, was just going to take it to racepace and get the boys to fix what evers wrong with it.
noticed the block looked wet behind the rear dump pipe.
will report back once its on a stand.
