HC-AZ Posted January 11, 2005 Posted January 11, 2005 I need to get a 76mm head gasket for my D16z6. I thought I could either get one from Golden Eagle or have them make me one, but they are out of stock and will not make any right now. Any idea where I can get one or have one machined? Quote
bernardo Posted January 12, 2005 Posted January 12, 2005 are you talking about thickness? if so try Cometic i think the thickest they make now is 75mm. They aren't real fast if it's not in stock, or you can make it yourself, just make sure you turn all the pieces the right way. bernardo Quote
bernardo Posted January 12, 2005 Posted January 12, 2005 Cometic, also has that. Probably in stock. bernardo Quote
HC-AZ Posted January 12, 2005 Author Posted January 12, 2005 Are the Cometic gaskets as good if not better then oem? Quote
bernardo Posted January 13, 2005 Posted January 13, 2005 yes their very good gaskets. Just out of curiosity, you over bored 1mm I don't have a Z6 I have a A6 and our stock gaskets are 75.9 mm stock, yours are probably the same, i can't see why you need a 76 if that is the case. bernardo Quote
HC-AZ Posted January 13, 2005 Author Posted January 13, 2005 I put the oem gasket on the block and it looked close. I just didn't want to take a chance of any of the gasket eventually breaking off into the combustion chamber. There were slight edges around the cylinder wall, so I was just trying to play it as safe as possible. Quote

Danny - I talked to the guys at the machine shop and my Honda shop and they both said that it would probably be ok as long as there wasn't (much if any) material hanging over the cylinder walls. However, I'm with you. I still would rather play it safe, but I'm not sure where to get what we need. Also, I thought that you'd said something about using copper spray on the head gasket, but my machine shop guy said not to use anything at all on the head gasket because the head needs to be able to move around on the gasket, so you don't want any kind of sealant that would keep that from happening. Just thought I'd pass along the info. Let me know if you find somewhere that can get the size head gasket we need. - Scott Quote

I don't think that would be very good for our CR. BTW - It looks like you may have been right on with Cometic. http://www.importperformanceparts.net/imports/cometic_acura.html Looks like they have one that lets you go up to 78mm bore. Thanks for the tip Quote
HC-AZ Posted January 14, 2005 Author Posted January 14, 2005 Golden Eagle put the sohc gaskets back into production, so I went with one of those. Golden Eagle bores the oem Honda gaskets and I know Honda makes good head gaskets. I would not run any gasket that hangs over whatsoever. That can easily become a point of detonation. Regarding the copper spray, I know of some very very good engine builders that use copper spray when building Honda engines. The machine shop saying the head needs to move doesn't make and sense to me since there are dowel pins that hold the head in an exact spot. I think the head moving around at all would cause more problems then less. We will just see who’s engine is faster Quote

I think the machine shop guy meant that the head and block expand at different rates as they get hot since they're not the same type of metal. Thus, there has to be play for the different expansion rates. I'm sure if you know people who use it, it's fine. I just thought I'd pass along the (mis?)information. So, did you have to send a head gasket to Golden Eagle, or are they just sending you one pre-bored? We will just see who’s engine is faster Let's see how fast your precious motor is with sugar in the gas tank! Quote
HC-AZ Posted January 15, 2005 Author Posted January 15, 2005 They are sending me one pre-bored. Lets see what happens when you put sugar in my tank... I remember how much you weigh. Quote
