Intake Plenum leak.

Intake Plenum leak.
Hello all I keep getting vaccum leaks around the intake plenum which is causing my hunting idle, I used a brand gasket and some ultra black gasket sealer but for some reason I cannot get this to seal, I even took it back off and applied some more sealer but no luck, it any ideas?
#2
Where is it leaking? does it keep moving around, or the leak starts in the same place every time?
generally you don't use any sealer on it. I've always used the OEM gaskets and they work just fine.

Hey Cape, the plenum keeps leaking making my car surge in idle. I had taken it to someone who a put a straight edge on it and claims it's straight but it continues to leak. I've tried everything from one to three gaskets at one time and no luck. I was thinking about having a machine shop mill to ensure it's straight, any ideas?

i don't get why that part, of all parts of the car to get warped, would be warped..... yes it's aluminum but it doesn't get THAT hot... unless the car overheated and just warped everything.

Ok, new update I took the collector and the plenum to T-Hoff in Raleigh, NC to see if they could mill the collector #14013M and the lower collector #14013N (illustration below).

They put a straight edge on both parts and didn't see any warpage and would have had a problem trying to bolt both down to mill them anyway. So at this point I went to Southern States Nissan and talked to a veteran mechanic name Gene. He looked at both parts and the only thing he could see was the fact that due to over tightening the bolt some thread was lifted. He believes that this may the cause of the issues I'm having with the gasket not seating and high recommended Permatex Anaerobic Gasket Maker Tube after using 400 grit sand paper to fix the thread issue. Cape I know your going to see this and I remember you telling me it took an hour to buff out your friends manifold so tell me what exactly did you use and how you did please, Sir.

not to mention i've never installed an intake plenum before....

Ok, group big question I'm hearing a loud pssssssssssssss sound coming from the intake manifold/injector area after getting another plenum/collector with new gaskets. I did put new injector seals and fuel rail spacers in after I inspected the injectors. The black spacers? Are they suppose be on top of the fuel rail or does the fuel rail sit on top of the spacers?

Thanks!!
Hey, Cape the problem was that I had the fuel rail spacers on the bottom of the fuel rail causing the injector seals not to sit flush. I watched my seals jump up and down... as I revived the engine....LOL. I've chased this leak for a month and had the manifold off more than ten times with numerous gaskets etc. Now the car is running great after putting the spacers on top of the fuel rail!!
