well after another two days of work on the datto turns out monotourque head gaskets are not cut properly!! they have been cut and stamped back to front and wont seal properly also they are only set up for early a series with the small hole for oiling not the round the bolt oiling

where wont it seal properly?

can't say i've ever had an issue with them, all the holes lined up ok...

have you got pictures??

I never use them for that reason, i've blown a few monotorque head gaskets but haven't since i stopped using them! espeically with a forced fed set-up. Go for a Nismo gasket, you can't go wrong! make sure the head is dead flat and it should be all good.

yea well i cant justify $180 for a fibre head gasket when i could make copper ones for less, the hole for the bolt that there is supposed to be oil feed past is tight on the bolt so oil would struggle to feed past. and all the silicon sealant for the aluminium side is printed on the wrong side of the gasket.

I have been using them on my racecar engines for years without any probs. Unless this is a new issue with the gasket manufacturing process, i had always given them the thumbs up.

yes the Nismo ones for balls out, and even GX ones for hotties, but monotorque all day for everything else,

do you have pics of the faults? have you told ACL?

why is the silicone supposed to go up? there's just as much underneath the gasket??

I used monotorque on my A14 for a few seasons of supersprints and never had a drama, I used a chinese one once and it shat itself big time. But never had a drama with the ACL ones. Use a nismo one now due to 79mm offset bores.

acl is subbying out a lot of there stock
gaskets,pistons,ect

I think ACL have gone broke
