[626]95-GSR

Changing my headgasket very soon..
i just have one question before i go to Honda and pick up a headgasket. Will the Y8 headgasket fit the d16a6 head and match all the coolant and oil passages with NO modification? In other words, is this a straight swap? or should i just buy the d16z6 headgasket?
also, anything else you guys recommed i do at this time? and suggestions on removing the head? thanks

need to know

crxgator

it will fit and should bump compression...you should get new head studs and your head milled...

[626]95-GSR

still need to know

The present head is milled already, so the head studs are an idea.

the y8 HG will fit with no problem. the only differences are some of the coolant passages in the y8 gasket are holes where they are slotted in the a6 HG. i just slotted them so that its the same...but i dont know if it is really necessary. it only takes about 10 minutes to do with a dremel.

also consider the 2-layer y8 HG (0.025" vs. 3-layer 0.037")...should bump the compression by about another 0.2 points depending on setup.

the z6 HG is the same thickness as the y8 3-layer but costs twice as much...i dont know why though.

u contradicting urself.... if they are diff tickness... and then they are not

Bottom line. the Y8 headgasket bumps compression a lil more than the Z6.... the Z6 is ticker period

from the info that i have the crushed headgasket thicknesses are the following:
D16A6 - 0.048"
D16Z6 - 0.037"
D16Y8 3-layer - 0.037"
D16Y8 2-layer - 0.025"

i know that the D16A6 and D16Y8 3-layer measurements are correct because i have double checked them by measureing myself.

i dont know where i am contradicting myself...and if the Z6 headgasket is thicker what is the thickness?

also when you dremel out the 3-layer Y8 HG you are only removing material from the middle layer...and its only 3-4 sections that are different. if there is a chance that that somehow "***** up" the headgasket then dont do it, since i added that i dont know if it is necessary.

i modified my 3-layer D16Y8 headgasket and it didnt harm it in any way... i have about 5-6k hard miles on it and i havent gone through a drop of coolant or oil or had any problems at all with it. but maybe its just waiting to blow? dont dremel it then....problem solved.

sorry if i posted missinformation...i just figured since i have experience with this i would post. as for the HG measurements...my bad for assuming the info was correct. if anyone has a used Z6 and used 2-layer Y8 HG, send them to me and i will measure them and post the correct info.

when you are speaking of the 2 layer y8 headgasket, are you talking about removing a layer or the gasket? will this ruin the overall structural integrity of the gasket?
also, thanks for the info guys.. looks like im going to pick up a Y8 hg today.

there is "supposedly" a 2-layer Y8 head gasket from Honda. i dont know what the part number is and ive never seen one since i didnt find out about this until after i had mine back together and running again.

i may be wrong about this also since i make the mistake of assuming certain things on the internet are true...see if anyone else has personal experience with the 2-layer gasket or call honda and see if they know what the hell you are talking about.

Hmm... I thought that the Y8 headgasket that I purchased from Honda was a 2-layer, but I didn't actually look at it to make sure! It did look different than the Z6 headgasket I had laying around though.

I guess I had always assumed that any Y8 headgasket was a 2-layer. Perhaps certain years of the Y8 HG change from the 2-layer to 3-layer (ie 96-98 = 2-layer, 99-00 = 3-layer). &lt;--- This is just an assumption.

http://www.hondaautomotiveparts.com has the same part number (18140) for 96-00 civic ex head gasket (yes i checked them all). that is were i ordered mine from and it was a 3-layer. also i pulled a head from a 97 auto d16y8 and it had a 3-layer. so i guess ??? on were to get the 2-layer. unless its just luck of the draw or a local dealer might have it listed.

well ill go to honda and check it out.. it doesnt make sense as to why Honda would actually make a 2 layer headgasket though. Shouldnt all the d16y8 headgasket be the same? I got a qoute from Honda today that a headgasket for a 95 Civic would be $57.

get the price from http://www.hondaautomotiveparts.com and see if they will pricematch it. ive heard of someplaces doing that. and the y8 is 96-00...the 95 would probably be the z6 and is about double the price. my y8 headgasket only cost a little over $20.

i have a d16a6 and am using a 3 layer z6 head gasket and no problem, the y8's are the same 3 layers also, i was just at honda today.

id also like to know about removing the center layer in the y8 H.G.

i got one for my a6 and need the extra .2 compression with my setup.
