When using a d16z6 head on a d14z2 block which head gasket has to be used?
The oem number for d14z2 is: 12251-p2j-004
The oem number for d16z6 is: 12251-p08-004

or are these gaskets the same?

i think yes but wait for Joris to verify

the d16y8 one and d14a4 are equal. three layer gasket. anyway, you can use the one you want, they both fit, but dont know for sure if those two are the same, Cheers

i remember Joris saying that he purchased a d16 gasket while he could be using a d14 one. They must have the same pattern even though not vtec.

I can confirm that you can use both gaskets. First time when I build my engine I had used d16z6 gasket, second time I used D14Z2 gasket.

Lets clearify:

D14A3/A4... etc. are the same as D16Y8. Three-layer metal sheet.

The D16Z6 is different but can be used as well, but is the metallic compound stuff, the stuff that is hard to get rid of when changing gaskets. The three-layer steel gasket is I believe stronger and way way way easier to remove may a failure happen, please go for the D14A3/A4/Z1/Z2 type.

thanks for clarifying =)

so if using a z6 gasket and it is not fully removed when changing gaskets, you may have sealing issues right?

you can use the 0,65mm metal gasket on every d series except the dohc ones.

good for some more compression increase

@ Polivias, strictly speaking yes. But removing the gasket is not so difficult, it is just messy.
