got sum new apex and corner seals from

hurley-engineering.ltd.uk .. and i specifically asked for 2mm seals for the 12a..


they friggen gave me 3mm..

i wonder why?

and the big question.. will it fit on my 12a?

is the 3mm a big difference? ie. is it better?

thanx guys

 

Arent all 12A seals 3mm? 2mm were on FC 13B's IIRC.

 

100% sure?

 

coz in the website theres a choice between 2mm and 3mm 12a

 

2mm seals are for Turbo aplication,if i remember correctly.

Karis

 

can anyone else confirm this?

 

oh crap i just remembered.. i am going turbo. thats the whole reason whil eim rebuilding my engine

 

2mm stock, 3mm are typically done for rebuilds, because the 2mm after so many miles can wobble in the slot, so the slot is milled out to 3mm. 3mm typically provides a better seal for turbo applications, but 2mm is more than satisfactory for N/A.

 

ahhhhh

 

WTF??? 12a's all came stock with 3mm. Maybe the 12aT's had 2mm(doubt it), but I know all of 'em over here were 3mm.

 

all 12a and 13b from 74 to 85 are 3mm 2mm are all 13b from 86 and up. so you dont get confused

 

All 12A's have 3mm seals standard except for the early twin-dizzy engines which had 6mm carbon. In other words, there's no such thing as a 2mm seal for a 12A. Hurley obviously knows this.

All 86+ engines have 2mm seals. You can put 3mm seals in these engines by milling the rotors. This is often done on turbo engines for extra protection against detonation or when the apex seal slot in the rotor is worn beyond spec.

 

2mm != 12a

 

no problemo..


thanx guys! for all your help

 

did you figure out how to change the oil yet timmy?
i would reccomend figuring out how do do that before you attempt a rebuild

haha

 

timmy, i hope those 2 thousand dollar apex seals you bought today make your car faster

*bows head in shame*

 

lol

 

Why'd you spend $2,000 for Apex Seals? You could've gotten two rebuild kits for that.

 

lol

 

I asked you a question.

 

Yeah, I won't even spend the normal amount for apex seals, that's why me and my dad are making our own! Are they ceramic? How'd you manage to spend $2000?

 

he spend 2300 AUD on apex seals
2300 is 17XX in american dollars

-greg

 

he called them "hurleys" the seals that is

-greg

 

$638.17 is the total for a 12a rebuild kit, you could've had two and still had ~$500 left over.
