ewaugh Posted November 2, 2013 Share Posted November 2, 2013 Okay so when I turn the car off I get sucking sounds, like it is pulling in air, from the area of the surge tank. Along with this is gurgling in the same area and a bubbling of air in the expansion tank. I know the bubbles are usually an indicator of a head gasket failure, but the air sucking in lead me to believe otherwise. I'm just not real sure where to start. Any thoughts? I bought the car at 123k with a rebuilt motor and new turbo from where the dealership owners kid was driving around with a blown turbo and cracked the ring lands on the pistons. I'm not at 129k. I also put a new radiator in a couple of thousand miles ago. Link to comment Share on other sites More sharing options...
ewaugh Posted November 2, 2013 Author Share Posted November 2, 2013 Oh and temp has always been normal, except for when my radiator esploded, but even then it didn't get above 3/4 up on the gauge. Link to comment Share on other sites More sharing options...
JJr Posted November 2, 2013 Share Posted November 2, 2013 It could be air in the system from when the radiator was changed. Link to comment Share on other sites More sharing options...
rob-2 Posted November 3, 2013 Share Posted November 3, 2013 I would try re-bleeding the system. Then monitor. Link to comment Share on other sites More sharing options...
lee07 Posted November 3, 2013 Share Posted November 3, 2013 Yeah, try bleeding it of air for an hour Link to comment Share on other sites More sharing options...
Max Capacity Posted November 3, 2013 Share Posted November 3, 2013 You need to jack up the right front corner of the car and remove the turbo tank cap and start the car with the heater on high. Watch the air in the tank, top off as needed. Squeeze the hoses too. I like Peak Global or Prestone, my new ej257 has some of both in it. Also check the coolant a few times a year, top off as needed. I have two gallons of Prestone 50/50 in the shed. I mixed one full strength bottle with 50% water. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

Mr. Sinister Posted November 4, 2013 Share Posted November 4, 2013 Check the radiator cap to make sure it's functioning properly. If it is, I'd check the dump tube going into the overflow to make sure it didn't suction itself to the bottom of the tank. The upper radiator hose is usually collapsed when this happens.

ewaugh Posted November 4, 2013 Author Share Posted November 4, 2013 I put two new caps on it just to be sure. I'm going going to take it over to the auto shop on post and run a pressure test just to be sure, but I'll try bleeding it first. Link to comment Share on other sites More sharing options...

Jazz95 Posted November 26, 2013 Share Posted November 26, 2013 Any news on this one? Mine is doing the same thing...just had the headgaskets replaced, and it's still doing it. Not happy... Link to comment Share on other sites More sharing options...

With a bleeder can attached to the turbo resi are you getting bubbles while idling? If you are you have an HG leak. Link to comment Share on other sites More sharing options...

I'd also recommend using a radiator quik fill bucket on top of the reservoir while doing this procedure. Link to comment Share on other sites More sharing options...
ewaugh Posted November 26, 2013 Author Share Posted November 26, 2013 I pulled the TMIC off so I could get in there, found and fixed three leaks in the rubber lines around the surge tank. There is another line that is still leaking, it doesn't even have a clamp on it...down wedges between the bell housing, block, and up pipe. I'm going to have to pull the up pipe to get to it, but I didn't have gaskets the other day. So I'm still getting the bubbles but they are a lot less than they were. So I still don't know for sure that I don't have a HG issue, but I'm betting that I don't. Every leak was caused by those squeeze type hose clamps. Replaced them all with screw type. And my surge tank was also low on coolant. Fixed that too. Link to comment Share on other sites More sharing options...
Jazz95 Posted December 4, 2013 Share Posted December 4, 2013 With a bleeder can attached to the turbo resi are you getting bubbles while idling? If you are you have an HG leak. Nope...no bubbles. Just the crazy gurgling while the car is in motion and also crappy heat production inside the car. Some other threads have recommended changing both radiator cap and turbo tank cap, and that should alleviate the issue? Link to comment Share on other sites More sharing options...
FJuan Posted December 4, 2013 Share Posted December 4, 2013 I'm having the same issues with the heater core having the bubbling sound, I just tried rebleeding the the system again a few days ago and still have it. I'm thinking it could be the cheap caps sucking in air, since I bought them from an auto part store. Going to order 2 OEM caps to see if that fixes the issue. My wife's balls are delicious.

FJuan Posted December 4, 2013 Share Posted December 4, 2013 Believed I found my issue, and this may help others. It could be a possible actuator going bad, since the sound is coming from behind the cubby/vents area. http://legacygt.com/forums/showthread.php/noise-comming-ac-vents-after-turning-off-carii-183027.html My wife's balls are delicious.
