Can someone tell me if the bolt that holds the upper part of the breather tube is also the one of the bolts that go to the coolant flange on the rear of the motor? I already knew I had coolant coming from that area but ever since I replaced the breather tube for the 034 kit it is leaking much worse now. I had to remove it to put the new upper hose in its place which doesnt require it to be bolted since it is made of silicone and not steel. I still have it if so but will be a pain to put back in. Not going to waste my time if not needed. Thanks in advance! Oh and it is an 01 A4 with 1.8t.

 

What breather tube are you referring to? There are two 10mm bolts holding the flange to the head and two more 10mm bolts that connect to the metal coolant pipe.

 

The best way I know to explain it is that it is the metal tube going up the back side of the motor that connects to the three way rubber tube. The top part leads to the top of the motor and also branches off to another metal tube. The bottom of it connects to the breather tube that connects to the hole above the oil filter and branches off to the pcv valve.
