dangerman4 Posted September 30, 2008 Share Posted September 30, 2008 (edited) yes i have done it several times, if you double the bag over it will hold nearly 2 bar. 2 bar coming out thru a leak makes a loud noise so its easy to find and then fix. who knows he may have 3 or 4 leaks. i know last time i did it i had 2 leaks in regards to which hose it dosent matter as long as its a vacum hose. ie the fuel reg, a ebc, bov line, they are all about 3 - 5 mm inside diamater which fits snuggly over your air comp nozzle. simple tight seal that you dont need to hold onto just charge it up with a couple squirts of air and then go hunting for leaks.

Sinful Posted September 30, 2008 Share Posted September 30, 2008 Just had this problem on a mates R34.. I know its a pain in the arse and a bit late now if booked into Morpowa Thursday..\ but we : Took exhaust off to see if it was blocked... it wasnt cause was still idleing shit with it off. He then pulled all the vaccum lines and intercooler piping off and check for cracks, perished lines. He could also hear a air leak like you and eventually found that the O rings on the injectors had perished and sucking in air.. Have you check that the actuator on the turbo is attached correctly? Had them come loose in the past also Good Luck!! these things definately test your patience Link to comment https://www.sau.com.au/forums/topic/238245-what-the-fk-is-wrong/page/3/#findComment-4166251 Share on other sites More sharing options...
craig R33 Posted September 30, 2008 Author Share Posted September 30, 2008 yeah the leak is coming from the left hand side.... could well be the injector seals Link to comment https://www.sau.com.au/forums/topic/238245-what-the-fk-is-wrong/page/3/#findComment-4166266 Share on other sites More sharing options...
4door_Sleeper Posted September 30, 2008 Share Posted September 30, 2008 If you get a length of garden hose (about 1m) you can hold 1 end to your ear and the other you poke around the engine bay (running or not). It will act like a doctors stethoscope and help you accuratly locate noises (vacume leaks) in places you can't/won't get your ear to.

craig R33 Posted October 1, 2008 Author Share Posted October 1, 2008 i did the compressed air trick, but didnt hear any leaking air, so its looking to maybe be something worse? not happy Link to comment https://www.sau.com.au/forums/topic/238245-what-the-fk-is-wrong/page/3/#findComment-4167798 Share on other sites More sharing options...
nisskid Posted October 1, 2008 Share Posted October 1, 2008 did u check the lines off the plennum? they are after the TB so the test wont reach the plennum if that's where the issue is.

dangerman4 Posted October 1, 2008 Share Posted October 1, 2008 did u check the lines off the plennum? they are after the TB so the test wont reach the plennum if that's where the issue is. ummm think about it... if his pumping air into a vac hose they all come off the plenum, so therfor the whole system is full of compressed air both before and after the throttle body, its not hard to open the throttle if your concerned about the air getting past it. does your car sound a little like a wrx at idle? as there were no air leaks my finger is pointed at the ringlands. at least one piston, probally several of them. rebuild time.

nisskid Posted October 1, 2008 Share Posted October 1, 2008 lol at rebuilds and serious issues. if it's serious u will see a lot of light bluey grey smoke, if it's black u can be almost guarenteed its a little stupid niggling issue any decent shop will pick up on within a few hours if that.

Carbon 34 Posted October 1, 2008 Share Posted October 1, 2008 sorry to here u didnt find it mate, the squirt bottle trick works to find the o ring issues on the injectors, the mist of water cause the cyl to miss fire and you can hear it in the idle easy. same thing for leaking vacuum lines and gaskets. what colour was the smoke ? did u notice i described the types of smoke and main causes for them earlier in the posts? working on race cars for years i know a little bit about them....lol more then i care to sometimes...lol but since i didnt win the lotto i have to wrench my own cars except warranty stuff. good luck mate Link to comment https://www.sau.com.au/forums/topic/238245-what-the-fk-is-wrong/page/3/#findComment-4168779 Share on other sites More sharing options...

DSTROY Posted October 1, 2008 Share Posted October 1, 2008 when my rb20 did a piston, i only noticed cos of the weird sound at idle, boosted hard for the months i drove it around till i did the conversion. It never made the the sound your talking about under boost, def sounds like a turbo/zorst leak.
