thecryoflove Posted January 3, 2009 Share Posted January 3, 2009 (edited) Hey all. A brief history of the issues of my '86, manual transmission, 1.8 L, ea82, Subaru GL wagon. So I came back to Ellensburg, WA early December (central washington) where my baby was parked for about 3 months. She ran wonderfully for a while. Then came gurgling behind the dash... few weeks later she overheats. Top her off with antifreeze and she still overheats. Change the thermostat... works better, but only for a few hours then overheats again. At this point the overheating is like this... temp climbs steadily and fairly slowly until gets to the red, then maybe back down below (but still high), then back up again, and then evens out at running temp instantly. I (unfortuantely) have a digital dash in this thing so I'm also wondering if maybe it's lying to me. Anyways, I must also mention that at this point she only overheats when the heat is ON!!! 2 seconds after I switch it from hot to cold she evens out instantly temperature wise. So I parked her on an incline and ran her with the radiator cap off and she expelled lots o bubbles!!! FInally after about 45 minutes of burping her I installed a new radiator cap and let her be. Seemingly it fixed the problem (idled for about 45 minutes without budging from running temp). Took her in to town.... overheating and now the hot/cold does not affect anything...she just overheats no matter what. Woke up this morning (burped her yesterday) and some new gurgling behind the dash... I am positive she had all bubbles out of her yesterday. So now... please tell me my head gaskets aren't screwed. Tell me there's an easy fix.... please! I should also mention that when I was burping her the upper radiator hose was, of course, warm. Then when I took her in to town after that (when she overheated) i checked the upper radiator hose and she was cold!!!!

subiemech85 Posted January 4, 2009 Share Posted January 4, 2009 what t-stat did you use? buy a lev-r-vent cap and run it in vent position Link to comment Share on other sites More sharing options...
Durania Posted January 4, 2009 Share Posted January 4, 2009 Gurgling behind the dash is a big sign that you have an air bubble in your system. Did you jack the front of the car up when you were purging the system of air? Link to comment Share on other sites More sharing options...
Subarule Posted January 4, 2009 Share Posted January 4, 2009 I think you need to burp it. Link to comment Share on other sites More sharing options...
Gloyale Posted January 4, 2009 Share Posted January 4, 2009 I could tell you it's not the head gasket, but it is. Sorry. There is a slight possibility that the t-stat you got sucks, replace it with a genuine subaru one. I mean it. Also you're digidash is likely not accurate, when it indicates hot, are there other signs of overheating? Steam? boiling over? loss of power? These are things to explore but, you probably have a bad headgasket. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 4, 2009 Share Posted January 4, 2009 Likely a head gasket yes. They aren't hard - an afternoon job. Do them on general principle - if they aren't bad, or only slightly bad, they will fail soon anyway with all the overheating you have done to it.

thecryoflove Posted January 13, 2009 Author Share Posted January 13, 2009 First off, sorry for the delay, it's been crazy... For me head gaskets aren't an afternoon job =) I did burp it and it belched a lot, they came back (and pretty much instantly...only drove 10 miles before it was gurgling like a SOB)... now also...after letting it sit for a while longer (it's in timeout) it is spiking and jumping on the tacho when i get to about 3000 RPM's... I'm really hating this digi dash... oh, and still overheating is there a standalone thermometer i can install to check temp? Link to comment Share on other sites More sharing options...
Caramanos2000 Posted January 13, 2009 Share Posted January 13, 2009 If its gurgling and overheating why are you still driving it, you could toast it driving it HOT all the time Link to comment Share on other sites More sharing options...
thecryoflove Posted January 24, 2009 Author Share Posted January 24, 2009 Ok... I;ve toasted it. Ever since I've owned it it has had a tick that goes in and out intermittently, but a couple days ago it started rumbling (the engine) like it never has before. Then I parked it for 1 minute while I ran into Hollywood Video and returned to her not starting. She's turning over but it's a high pitched noise and she refuses to start. Does this sound like head gaskets? And if it is my head gaskets, is there any way I can check the heads themselves for warping or cracks, or di I got to take it in for that?
