ok are you sayting you have a D15 block w/ a D16Y7/8 head? that's what I know of as a mini-me setup.
you should use the Y8 Gasket as it is a little better metal gasket then a Z6 gasket some use w/ a mini-me.
Are you reving the motor extremely high or anything?
Good luck and hope you find a cure/answer.

maybe you need new head bolts maybe invest in some arp head studs?

LShatchie

do u rev ur motor to like 8k or somthing? the metal headgasket shouldnt be blowing like that

get the head resurfaced.

might be warped.


boosted D's have problenms with head lifting.

SOHCD16y8

try some arp head studs, or at least new bolts, did you have the block resurfaced too, that could be your problem also

RedDC5

I agree, resurface and new head bolts.

Exactly. You are supposed to have the head resurfaced every time you change the gasket.

do i need to acctually take the block out of the car to get it resurfaced? that sounds a little too much of a mission to do. the block has 70k miles on, i wouldn't think thats necessary. what do you think?

I heard the d-series heads are prone to warping when removed from the block. You gotta make sure the motor is cold before you try removing it from the block. Try getting it milled.

LShatchie

yes your supposed to get the head milled everytime you change the headgasket, usually the block you dont do, unless it really needs it.. there is a test to see if its warped you basically take a straightedge and u put it on the block in a few different spots and you put a light on the other side and check if you can see light..

the way i always saw it was that as long as you have one perfect surface (the head) the gasket is made to take a litle imperfections left (on the block)

awsome very helpful information thank you very much im gonna get the head milled

Any body from S FLA knows a good/honest machine shop to get this done? i know brads performance any body else?

gabspeed

anybody knows whats the difference from a d16y8 head and a d16z6? how can you tell the difference?

civicminded92

You can tell which head by the head code:

Might want to check the block also, as it may need resurfacing. Are you cleaning both surfaces well before putting the new gasket on? And, if so, how are you cleaning it? That could be your problem right there.

Very good info thanks alot
i clean the block with degreaser with what im i suposed to clean it with?

civicminded92

If you don't get all the old gasket material off, it will cause weak spots in the seal of the new gasket. As long as you can see it's all off, degreaser should work ok. I used really fine grit sandpaper (1200+) to get all mine off. You can also use a scotchbrite pad - anything that's only VERY MILDLY abrasive. I just don't know if degreaser alone will get all of it off...


I was really just hoping you weren't going to say something like a grinder or sander. That would be bad, mmmmkkkk?

At this point though, I'd get the deck check on the block and the head. There's a section in Helms that shows you how to do that with a machinist's straight edge and a feeler guage.



Only shows the head, and it's for the 5th gen cars, but I'll be it will be very similar for your setup.

Hope this helps....

gabspeed
