Make sure you either anneal, or use new copper exhaust gaskets.

Otherwise, the torquing will be for naught.

BTW, where do you keep your 914 in NYC? It has been a long time since I've seen a teener running around Manhattan.

I don't believe any torque spec is in the Haynes manual. I thought that the exhaust studs were torqued to 14 or 14.5 ft/lbs (because they're going into aluminum and the copper nuts that hold the HEs on were 12 ft/lbs.

Someone please render a decision.

Cool, I was in Park Slope for a few years but my teener never saw the mean streets (kept in storage, upstate).

Loved P. Slope and Prospect Park.

I am about 16 mi west of the city, let me know if I can help out. I've been through most everything on 914s, just never rebuilt the transmission.

probably will, just put the rocker assembly back in with new screw, the h.e'. and the flapper box and it's running again. gonna pick up a new carb linkage na dtry to put together a wrenching party, maybe with ray mital in n.j. will let you know. if you come to manhattan, i have a southwestern/mexican restaurant on the upper east side, 914 owners eat free

I am in Manhattan everyday, and I love Mexican/southwestern food.

Let me know when the wrenching party is, I'll try to be there, or I can offer my garage if that works for you all.

(IMG:style_emoticons/default/agree.gif) That's right. M8 into aluminum is only 14 ft-lbs. Remember that though the nut is steel (copper-plated only!) the torque is distributed down the length of the stud, and the other end goes into aluminum.

I have the Bentley manual for VW T4, and it states 14 ft-lbs also, IIRC.

Interestingly, M9 into aluminum is about 17 ft-lbs, which is about the same as M8 into steel, so if you're running 9mm/8mm step studs, both ends can handle 17 ft-lbs, and you can go a but tighter.

Someone correct me if I'm wrong, but didn't the 1.8 came from the factory with the 9mm/8mm step studs. My theory is that this was part of the reason. Similarly, the rocker studs are 8mm/7mm step studs, with the big end going into the aluminum head- same reason? Who knows!

i torqued them down at about 15 lbs (tough to be accurate stuffed under the car), ran it for an hour nothing flew out of the valve train. just might get it off the jack stands this week (IMG:style_emoticons/default/driving-girl.gif)
