I bought a used zzp dual pass from a member on this site and cant get the middle inlet to stop leaking. I am at my wits end, any tips or suggestions?

 

RTV or buy a new endplate gasket.

For RTV, I'd get "The Right Stuff" by Permatex

what he said

this is the performance section not my **** is broke section please post it the correct section

Problems/Service/Maintenance - Cobalt SS Network

 

Is it leaking from the nipple through around the house? Or between the intake manifold and the plate?

I would say buy some new hose clamps and try different positions and tightness, just worked on mine for a couple of weeks. Finally got everything right

 

fitings are press in....ive had them where i can pull them out by hand... jb weld is what zzp has said to do numerous times.

 

^ You sir need to get a life, and shut the hell up for once.

 

Why are you such a douche?

 

Guy has more of a clue then 90% of people on here so take his advice.

he could of said use the search like everyone else since this is a known issue

 

This forum wouldn't be what it is if he shut the hell up.

And he is just trying to keep the forum organized, someone's gotta do it.

 

This.

MrB is right, problems and service is the correct section to post this in.

Thread moved.

As for your problem, the ZZP dual pass endplates are known for leaking. I would have looked into that before purchasing.

But if you are set on keeping it, get some RTV sealant and seal her up.

 

some of them cant be saved. go buy a GM one from CED no problem. I have had 100% success with the ZZP endplate, flowing epoxy around each nipple before install, and facing the mounting surface flat. BUT I do that when its new, and some folks have reported that they tried that and it didnt work.

75 versus 200. tough choice.
but you bought it used OP and maybe the seller got rid of it for a reason, sad to say.
back to GM OEM what I use.

 

^^^^

zzp said to jb weld it.... the customer I have had tracks his car. after 8 months the jb weld broke apart. its hit or miss with their end plate. I know people have had success with tehm

 

This.

That's the one I run, and never had an issue.

 

I JB welded the outside of mine. I had same problem. Would seal up if it was warm but once it was cold it leaked pretty good.
