so ive got an 03 z and i put the spacer in about 4 months ago,i noticed the car was running kinda louder than normal and was hesitating off the line so i find out the spacer was leaking,i tightened down bolts and worked fine for a week and then it leaked again.so i took it apart and added some intake sealant all around.worked good for a few days and its leaking again.so how can i take care of this,once and for all..also i went and got dyno the day i sealed it and came back with 240 hp and real low tourqe numbers..is that normal for an 03 auto..by the way its the motordyne spacer...any help?

 

did you soak the gasket in oil first?

 

the smaller gasket yes, but the bigger gasket that seals the plenum,no..didnt see that in the instructions,it says only the smaller..?

 

sorry just noticed im in the 370 section..

 

It may not be the spacer leaking at all. It sounds like you may need a throttle body reset procedure.

Its listed on the last page of the installation manual.

Try it and let me know what you find.
