So i replaced my d16y7 IM w/ a IM from a y8, now i noticed that there is a leak coming from the IM...it does not look like the IM sits flush against the head b/c the y8 head is diff. but most threads said that this should not be a problem...should i just try replacing the IM gasket????

well did you use a fresh one?

of course you're supposed to use a new IM gasket but if you are absolutely cheap o like I was when I did one years ago...RTV that bad boy up and voila haha

OMG you didn't use a new gasket?? shame shame

I had no such problems.

i bought a new gasket for the y8 now and i put it in...its still ssucking air from those corners

imported_chris_v2

thats odd.... only thing i can think of is the flange is warped or damaged.

would getting a y7 gasket fit better? because it sits against the head flushed? where as the y8 gasket overlappes

imported_chris_v2

wait till bruno chimes in. he's done the mini-me. I would assume both gaskets are the same. But guess not.

I've noticed that there are four holes on the top of the manifold exposing the injectors i believe - after seeing this it seems as though this is the cause of the leak b/c that top section of IM does not sit flush against the head
*that part of the manifold is exposed - i've never seen this problem in all the forums...
for an easy swap this is becoming frustrating

weaksos bro... what kinda broke *** manifold did you get??

lemme try to get those pics for you



hmmmmm only relevant pic I could find. if you isht doesn't look like this, it's not a Y8 manifold. gasket I used was a Y8 prolly but I don't remember.

Cynikal.Mindset

those little holes are normal...are u torquing down the manifold bolts in an alternating sequence?

imported_tspoon

that manifold you got came off a 99+ civic si or an EL ...those cars have air injection into the injectors therefore you cannot use that manifold on a y7 head, try getting a 96-00 civic si or an older el w/o air injection IM

yup, what tspoon mentioned above is correct.

however, you can still use that IM with your Y7 head.
just cover/fill those holes with some JB Weld.

Hey James, Justin told me that smoke was coming out like mad today, is everything all good now???

J2000

ya...ahah the smoke was caused by the coolant in my engine(luckily avoided hydro lock)
man it was smokin' couldnt see anything across the street
ya everything's good now filled those holes good no leaks anymore

If you need a y8 IM, there is a 97 si civic at Standard Auto Wreckers with the motor in the car still. I was there on thursday.
