Can anybody tell me the head torque specs on the 1.7? I'm burnin the midnight oil
trying to get this engine done for a friend and I misplaced my book. I think I remember something about not fully torqueing one side, but to evenly do each side at a time in like three steps. I'm staying up till this is done so please help a fool get some sleep. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |

23 foot/lbs. But make sure you follow the torque diagram.
And don't overtorque them. Some mechanics with lots of water cooled experience will look at the 23 foot/lbs. and say "Naaa.... that's gotta be a typo. Must be 83 foot/lbs." Then they promptly torque the hell out of the nuts. Bad thing. It can cause the head studs to pull out of the case when the engine gets hot. Trivia for the day.. From a cold start up to fully warmed up a 914/4 motor grows 1 inch wider. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) |

Cool, I remember it being really low. I'll divide that into three steps and torque both
heads evenly. My friend put this together last year with the head rings and #3 blew out. He kept driving it thinking it was an exhaust leak, so it melted the head and cracked the cylinder. |

23-24 is fine. I use 27, BTW. IMO, the head gasket probably blew because the head wasn't flat, not because it wasn't torqued properly. The Cap'n
