shortlid Posted January 4, 2014 Share Posted January 4, 2014 I tried to replace the PCV on my '03 Legacy GT. However it was - 3 degrees last night and the hard line that goes to the PCV was too hard to disconnect from the PCV. You guys have any ideas?

nipper Posted January 4, 2014 Share Posted January 4, 2014 I would wait for the weather to warm up. The rubber will not be pliable at that temp. Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 5, 2014 Share Posted January 5, 2014 Run the engine until its warm then the hoses should be as pliable as they'll ever get. Be careful not to break the large hose that runs down to the block. Link to comment Share on other sites More sharing options...

Downbound Posted January 5, 2014 Share Posted January 5, 2014 Try heating it up with a hair dryer. Link to comment Share on other sites More sharing options...
nipper Posted January 5, 2014 Share Posted January 5, 2014 Hair dryier isnt a heat soak, its a spot heat and you can burn yourself or melt the rubber easily. STarting it may be best, but better wold be drive it and let it cool down then attack it. Link to comment Share on other sites More sharing options...
Gloyale Posted January 5, 2014 Share Posted January 5, 2014 Ok the PCV screws into the block corrct or is it up at the intake end? intake teh fitting in the block is just that.....a fitting. Link to comment Share on other sites More sharing options...
nickb21 Posted January 5, 2014 Share Posted January 5, 2014 (edited) Did they really flip back and forth? On my '02 OB the PCV is on the block (thought it remained on the case for at least the rest of that gen). I know 2000's(all?) were on the intake.

STarting it may be best, but better wold be drive it and let it cool down then attack it. I don't know any standard hair dryer that will burn a person. If hair dryers got that hot every woman with long hair would be in trouble! If you are talking about one of those heat guns that looks similar to a hair dryer, that is a different story- those will do some damage (to your head an the hose). I've done some excellent work with a hair dryer and frozen washer fluid lines. The only thing melting was the water in the washer fluid. Link to comment Share on other sites More sharing options...
nipper Posted January 5, 2014 Share Posted January 5, 2014 I have gotten burned with hair driers, they will burn. Espcially in the hands of a clumsy barber. Link to comment Share on other sites More sharing options...
idosubaru Posted January 6, 2014 Share Posted January 6, 2014 definitely don't touch that thing when cold. i've broken a zillion hoses. at 10+ years all the rubber is prone to crack anyway, definitely get it up to good temps, even then they're prone to crack.

shortlid Posted January 14, 2014 Author Share Posted January 14, 2014 Ok weather warmed up. Got hose off, however the part screwed into the intake is just a stright though fiting. The PCV must be screwed into the block end. Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 14, 2014 Share Posted January 14, 2014 It does appear that at some point they switched it from the manifold to the block. Not sure why. Keeps the crud out of the hoses? Maybe less likely to clog? Link to comment Share on other sites More sharing options...
shortlid Posted January 14, 2014 Author Share Posted January 14, 2014 (edited) There was so much crud in the nipple fitting and PCV. Also I got a Fram PCV and the nipple is to big for the hose. Is this a dealer only part? Edited January 14, 2014 by shortlid Link to comment Share on other sites More sharing options...
1-3-2-4 Posted January 14, 2014 Share Posted January 14, 2014 I snapped two of these PCV hoses One at around 30F and the other around 49F thinking it would be warm enough.. NOPE.. so I sit hear waiting for the dealer to call me letting me know when it arrived. at least that I have the IM off I replaced the last three rubber vac lines under the manifold near the FPR.

Is this a dealer only part? OK so went to another autoparts store and only Napa had the correct PCV for my '03 but wanted $13 it was a Eshich brand?? All others has the style that screws into the intake up untill 2005 Model year?? Why are the style that screw into the block so much more expensive than the ones that screw into the intake.
