i picked up a hondata gasket for my 2k ex a while ago since it sounds like a worthy investment for $60. however, after a few hours of installing/reinstalling i realized why i still had a massive vacuum leak... it doesnt fit completely! i called hondata about it but i didnt get a straight reply, althought i was told it *should* fit. sure it lines up right, but it seems the notch in the upper part of the gasket between the 2 middle runners doesnt belong since the manifold and stock gasket dont have it.

personally, i think itll only fit a previous gen d16 from 96-98 but its advertised for 96-00. on their site it lists the d16z only though. hmm, d16s are fairly swappable amongst each other but jackson racing makes 2 diff kits for their superchargers, 96-98 and 99-00, just for the manifold basically. makes sense to me. has anybody else done one of these installs on a d16y8 successfully?

 

interesting...i was planning on purchasing one for my JRSC install.

does anyone else have experience with this?

was it an installation error??

Weird, it should fit, since most d series Intake manifolds are swappable and hearing most dseries guys using them. Make sure you really clean off the old gasket good or it won't seal, that may be whre your leak is. also, make sure it's flush when you bolt it down.

i cleaned off the old gasket and it was flush, the leak was coming in thru a gap that the hondata gasket did not cover... i could put a piece of paper in front of this gap and the motor was definitely sucking air in at this point (you would also have to be deaf to not hear it, and blind to not see the check engine light blinking like crazy). and by gap i mean its like 2 inches long by (digging back into memory) 1/8". its very noticeable actually. but like you said, the manifolds are swappable. im 99% sure it wasnt an install error since i did it twice to double check my work. beats me.

in fact, im going to be doing that very install soon myself. i did it before while na but decided to try again now. maybe another call to hondata is in order.

 

not sure what your gasket looks like, but ordered and installed one a few months back without any problems. it is advertised as for the d16z on the site, but it works fine with my d16y8 and JRSC. hope you can figure out what the problem is.

 

pics.

 

ok, in this first pic you can see the old gasket behind the hondata gasket. up at the top is what im talkin about, how it doesnt cover everywhere the manifold does. the more i think about it, it should seal properly anyway since the runners are covered. not sure why its sucking air, but its doing so here.


btw, anyone know what that round imprint is for on the old gasket in the middle?

the arrow is pointing to a spot on the gasket that was sealed before but when i called hondata, they said i should remove. i dont remember why though. i may be wrong, but i dont think thats the source of the vacuum leak. coolant was leaking from around there and i think thats where it was coming from (still i dont see how). the guy on the phone i spoke to may not have known what he was talking about.

now if i wasnt supposed to remove that section, then that may be my problem. however, like i said, i dont think thats causing the vacuum leak.

this is just a close up.


tekno... you didnt by any chance remove that piece did you?

 

what year is your car/motor? if it is a 99-00 EX, it is because of the air injection holes, which are above each runner. that OEM gasket forms a seal around those air injection holes while the hondata one doesn't...

so i am guessing the hondata gasket will work with all d-series engines, except for 99-00 EX, unless you plug up those air injection holes...

 

here are some pictures i found floating on ebay....

99-00 EX intake manifold w/ air injection ports.


96-98 EX intake manifold, notice how much less metal, and also no holes and no air injection nipple on the top..


i saw your first post and you said you have a 2000 EX, so most likely the gasket will not work for you..

interested in selling it?

 

its a 2000 ex... that sucks but i appreciate the insight

a gasket itself prolly wouldnt be tight enough to stop the leak, but i tried running the stock gasket with the hondata one. without saying, no luck there either, theres nothing holding the gasket to the holes.

how could i plug them?

 

i just used JB weld. worked for me.

 

interesting, I learned another difference in dseries parts

That would be the only way that the Hondata gasket will work.

 

so the hondata gasket shoud/will work for a D16Y7 correct??

Yeah, the air-injection was only on the Y8....unless I am having unbelievable memory fade for some reason! :D

 

haha u have to block off those extra lil holes on top of each runner had the same problem blocked them off and now its nice gasket should work.

 

how about suggestions for ways to block it off, but at the same time, have it easily removed if i want to. i never used it, but jb weld by its name seems fairly permanent. correct me if im wrong.

 

didn't realize there was such a difference in the 99-00 manifolds, i have a 98 so i didn't have the air injector holes to cover up. about the the square piece, i don't think i removed it as it was all solid. the manifold in that area is also blocked off so i don't think it would change anything, but i did this all a while back so don't remember the details. sorry

 

with the hondata gasket work with the d series edelbrock IM??

 

I'm getting a Y8 intake mani for my d15z1, will a hondata gasket work for this? i think it's a 96 so i'm guessing it will???

yes the only one u have to modify is the 99-00 one.

actually, if youre interested in buying it, make me an offer. you can see its condition already, but really its barely used since running with a vacuum leak just wasnt that 3% power increase i was lookin for or, if anyones interested, lemme know, i paid $60 for it.

i also see that hondata wised up and molded a new style gasket for us 99-00 d16y8 guys out there. its bigger, curvier, and covers all the holes with no problem. hmm, sounds like i could be describing other things. anyway, they its 92-00 "compatible" now instead of just 96-00 and im assuming the larger design satisfies all the manifolds. too bad i cant find that picture of it...

 

the cold start bs is worthless, just plug the holes bro. Jb weld.

 

yes, i suppose i could. i just dont like fudging things like that when i know theres a better alternative, namely a different gasket in this case. i know it sounds dumb but its my sense of perfection whenever i undertake a project. and thats read, sense of perfection=more money out of pocket. sigh.
