Where can i get s14/s15 injector seals and o-rings?
does 300zx ones fit?
And Whats the right way to pressure test for vaccum leaks?

Today i tried pressure testing my intercooler / intake manifold...I decided to make a tester out of parts i found around the shop. I basiclly made a plug for my intercooler piping that has a pressure gauge and tire valve. So that i could see if the cooling system would hold at lest 20 psi....And it doesn't, i found a bunch of leaks and the main ones coming from an injector seal.

I'm not sure if i did it the right way so i though i'd aak.

thanks in advance...

see oz s14 fsm, page EM-10.
item #7 is intake manifold, but just where the #7 points, should be a thick black rubber insulator.
i believe that your leaks by your injectors are coming through these; and not through the o-rings listed in the forementioned link, not possible.

16636-72P00 injector insulator (fwd sr20de) need four.

btw, that's a nissan part number, take that to the parts counter at your local dealership, say gimme four por favor.

hey mang, i am very very curious why you didn't replace the sprocket and why you didn't line up the links in your chain (http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&Board=UBB9&Number=67729886&Forum =All_Forums&Words=29522&Match=Username&Searchpage= 0&Limit=25&Old=allposts&Main=67729416&Search=true# Post67729886) while you had the front cover off....

Actually i lined everything up but i should of changed the sproket. i don't know why i never changed it...i guess i thought it would be ok. Do you think the chains gonna jump or would the missing tooth throw things off balance? I think i need the part number for that... http://forums.freshalloy.com/images/graemlins/blush.gif
And thanks, the injector insulators is the part i need.

I'll pick up set of o-rings and insulators...and if i can get a new set of intake mainfold gaskets I shouldn't have any leaks at all. Can i get one from nissan?

And i'm still trying to figure out if i'm pressure testing the right way. Is 20 psi to much?

i found the pressure testing info.. http://forums.freshalloy.com/images/graemlins/smirk.gif i searched using the wrong words last night. http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&Board=UBB9&Number=67481528&Forum =UBB9&Words=pressure%20tester&Match=Entire%20Phras e&Searchpage=0&Limit=25&Old=allposts&Main=67480117 &Search=true#Post67481528

umm, if you did line the links up correctly, you wouldn't have concluded that your engine's misbehavior was due to misaligned timing chain, that's why i figured you didn't line them up, but never mind.

crank sprocket, it's same parts as fwd sr20de crank sprocket.
i have a used one with full set of teeth. if you are in my area, i would trade it for a sandwich and a drink.

intake gasket for s14&s15, not available from regular nissan dealers. btw, the one between intake collector and the manifold, and the one between manifold and the head, are single layer steel and pretty much reusable.
