ns87 Posted September 12, 2008 Report Share Posted September 12, 2008 I've been searching for a vacuum leak and I've narrowed it down to the EGR area. The plenum and throttle body are not the source of the leak. Spraying starter fluid has no changed the idle at all. Is it possible that the EGR cracked somewhere on the underside? I'll admit I wasn't the most gentle with it when I had the plenum off. Quote Link to comment Share on other sites More sharing options...
IRONDOG442 Posted September 12, 2008 Report Share Posted September 12, 2008 Yes that happened on my Dad's S-10 the EGR base actually split. Quote Link to comment Share on other sites More sharing options...
Brian P Posted September 12, 2008 Report Share Posted September 12, 2008 that or the tube itself if it kind of sounds like an exhaust leak Quote Link to comment Share on other sites More sharing options...
pontiacmaniac94 Posted September 12, 2008 Report Share Posted September 12, 2008 that or the tube itself if it kind of sounds like an exhaust leak x2! good luck with that! they are a pain to get to and a pain to remove! Quote Link to comment Share on other sites More sharing options...
ns87 Posted September 12, 2008 Author Report Share Posted September 12, 2008 I've checked and rechecked everything under the hood. I replaced the plenum gaskets again. I double checked the PCV valve vacuum line. I even looked at those brittle vacuum lines (not the ones for MAP, vents, cruise), but the long thin ones above those (they're standing above the engine in the video). What are those for? that or the tube itself if it kind of sounds like an exhaust leak its a whistling noise, This is from a few weeks ago. It's not as loud, but pretty close. EGRs don't fail that often right? I should be ok with a JY one? I don't have emissions tests in my area, so I'm not too concerned Quote Link to comment Share on other sites More sharing options...
IRONDOG442 Posted September 12, 2008 Report Share Posted September 12, 2008 its a whistling noise, Did you install whistle tips without telling us? Quote Link to comment Share on other sites More sharing options...
ns87 Posted September 12, 2008 Author Report Share Posted September 12, 2008 lol, with the hood closed it sounds like a demented supercharger. Quote Link to comment Share on other sites More sharing options...
Night Fury Posted September 12, 2008 Report Share Posted September 12, 2008 Are all three of those vac lines installed above the TB? Something looks funny there... Quote Link to comment Share on other sites More sharing options...
ns87 Posted September 12, 2008 Author Report Share Posted September 12, 2008 They're supposed to be under that black metal plate with 2 7mm screws. In the video I didn't bolt it down yet. Just an update, I took off my EGR (in the pouring rain) and the right screw hole broke in half. I'm going to try to find a used one, but I might have to bite the bullet and buy a new one.

Crazy K Posted September 12, 2008 Report Share Posted September 12, 2008 WEIRD!!! I have NEVER heard a noise like that. I want you do do something. REMOVE the serpentine belt... and run the motor (but for no longer than 30 seconds to prevent damage) to see if the noise is still there, and not associated with a bad accessory. if the noise is gone... spin all the pulleys to see if one is grinding.

I have a stack of parts. LOL! PM me. Quote Link to comment Share on other sites More sharing options...
ns87 Posted September 12, 2008 Author Report Share Posted September 12, 2008 So the noise is from the EGR. Read below! They're supposed to be under that black metal plate with 2 7mm screws. In the video I didn't bolt it down yet. Just an update, I took off my EGR (in the pouring rain) and the right screw hole broke in half. I'm going to try to find a used one, but I might have to bite the bullet and buy a new one. I'm 200 miles away from home The top vac lines on mine just push in... Not the same vacuum lines. These may not actually be vacuum lines, but are not the ones that go in the throttle body. WEIRD!!! I have NEVER heard a noise like that. I want you do do something. REMOVE the serpentine belt... and run the motor (but for no longer than 30 seconds to prevent damage) to see if the noise is still there, and not associated with a bad accessory. if the noise is gone... spin all the pulleys to see if one is grinding. I just went out to do that, but once I reconnected the EGR the whistle got really faint/disappeared. . Weird thing is, the EGR is only connected with 2 of the 3 bolts because of this (camera phone): Looking down Yup that's a piece of the EGR base Took the car out, it drives fine. It just made a 200 mile trip yesterday fine. Once in a blue moon, the ECM freaks out (jumpy acceleration, stalls and won't start) and I need to disconnect the battery. I'm sure once this EGR is replaced, the problem will be solved. Thanks everyone (No EGR delete for me thanks!) -------------------------------------------------------------------------------------------------- I know the vac lines are a mess. It's only b/c I've been searching for this leak, but I'm 100% sure they all go to the same spot. I'll reorganize them once I get everything straightened out and fixed. They used to be so beautiful OLD pictureeee Quote Link to comment Share on other sites More sharing options...
