Hey.

I hope you can give some advice.

I bougth JG Engine dynamic engine. I assemble block and head, I used oem GE overborred 84mm head gasket, arp head studs, I torque 65 torqeu with arp molly.

We out together everthing.

We drove at 5 psi, about 100km. I pull it too 6000 rpm, I did it some times.

It started too leak on the 3 cylinder, the hole road was full off white smoke.

I have good A/F about 12-12.5 and only 5 psi sleeved b18c jdm engine.

managment system is crome.

some idea??

Jg sleeved blocks have been known to never be right. I personally know 2 people who have had sleeves that were messed up and wouldn't seal. Good luck getting them to fix it too.

Yea with the moly it says on the paper in the box with the head studs.

blackeg

75 psi with the studs. i think i did the oem specs with an additional step to 75. (27,61,75??? i kinda forgot lol). yeah i stripped a headstud nut on the last step. the stud is fine.

anyway ive had similar problems but to a less extent with aebs sleeves. i had the **** decked out of the block and it fixed it. also new oe gasket helped as well with a brand new set of headstuds

It is a lot of work too deck the block.

I will try with a new gasket and 75 psi.
