Default coolant leak passanger side Water jacket crossover pipe

I have a coolant leak on the passenger side where the crossover pipe connect to the block half. I have replaced the o-rings three times with no luck. on the third time i even put some PERMATEX® ULTRA GREY® Gasket Maker. I have not been able to find any kind of deformations on the mating surfaces. I always titting the bolts in an even x-cross pattern.

-EJ22T short block
-EJ257 STI coolant crossover pipe
-O RING-33.7x3.5 - (806933010)

I purchased from a board member another Coolant crossover pipe in hopes that it will seal better.

Does anyone have any words of wisdom. I am really getting tired at removing the intake manifold to replace the o-rings on the crossover pipe.

Could be a crack somewhere on the crossover pipe.

where does the coolant accumulate?

is it coming from the o-ring area or trickling down the coolant pipe to the o-ring area?

Try Permatex The Right Stuff gasket maker. The stuff works great it cures fast and has never leaked on me. As for the heater not working either you have air in there or your thermostat is stuck open not allowing the car to warm up all the way.

Sounds more like you need to burp the system, the "cold air blowing" is a sign there is no coolant getting to the heater core due to air.

Jack up the front end & run the car w/ the heat on it helps to purge the air out of the heater core
