you probably have a blown head gasket bro

dude, did you even read any of this??? I'm doing the head gasket friday morning
not to sound like a d!ck, but we all kinda came to that conclusion already, and talked a little about how I was gonna do it. wish me luck.

I was waiting for somebody to go off on him...

Good luck, bro...

hey what size socket am I gonna need for those head bolts?

[Inodoro Pereyra]

Head bolts are 13mm. But make sure you get a 12 point socket.

[myfirstmazda]

will do. thanks.

[Inodoro Pereyra]

Anytime.
Remember to clean up the threads in the block, and to lube the bolts before installing them (some people use engine oil, some grease. I use assembly lube, because I'm complicated... ), so friction won't throw your torque off.

Ideally, you should also replace the bolts, but, to be honest, I don't know if replacement bolts are even available...

[myfirstmazda]

the parts stores don't have them, and neither does the dealership, so I'm just gonna re-use the old ones. don't worry, I'll make sure it's all clean before it goes together.

[Inodoro Pereyra]

I just found them here!

Look them up. Ajusa and ARP have them.

wha? 13mm headbolts?

K series, and BP, and B6 headbolts are 12pt 12mm where I come from...

[Inodoro Pereyra]

You sure? I have a B8, disassembled right besides my bed (yep...), and it has 13mm... I know it's weird, because Mazda doesn't use 13mm anywhere else, but I checked it with my sockets, and the 12mm doesn't fit...

[myfirstmazda]

ok I wanna know for sure... is it 12 or 13? I'm buying the socket in the morning. and does it HAVE to be 12 pt. or can I do it with a 6?

[Inodoro Pereyra]

I just tried them again, in case I had made a mistake, and, sure enough, I did... Sorry.

It's a 12mm. Thank you Ryan for correcting my mistake.
You should use a 12 pt. socket. It's much more torque accurate than a 6 pt. one.

[myfirstmazda]

but a 6 will work if that's all I can find? the bolt's not 12 pt. is it?

[Inodoro Pereyra]

The bolt is 12 pt. You shouldn't have any difficulty finding 12 pt. sockets.
If you can't find it at your nearest auto parts store, go to Harbor Freight, if you have one where you live. You'll have plenty to choose from.
