The Stovebolt Site Forums The Shop Area Engine Shop torque wrench 4 the 235 manifold

Hi Everyone,
I was wondering, what tpye of torque wrench/breaker bar do you use to torque the bolts directly between the intake to head? (the center ones next to the carb)
Also what's the best wy without breaking these bolts off in the head when backing htem out?
TIA,
David

You can't get a torque wrench on those bolts. I do them by feel. Easiest thing is to practice on one of the bolts that is accessible, torque it down to the value needed for the interior bolt, the grab your end wrench and turn the bolt slightly. It might take a few times, but you can get pretty close that way.

If the manifold bolts are stubborn, soak them overnight with a good penetrating oil, I recommend Kroil or PB Blaster. Then warm the engine up and put on some gloves to remove the bolts.

Aloha! I use a snap-on "torque extension/adaptor", p/nFRDH181, it's 2-3/4" long, 3/8 drive on 1 end and 9/16 box wrench on the other, theres a formula to follow to make up for the longer length to apply to the setting on the torque wrench, it's complicated, and after i sat down and figured it out it only came out to few lbs below the normal setting so i don't bother doing it anymore, but if I install the extension/adaptor at a 90 degree angle to the wrench the wrench setting remains the same. Now I only use it because I happen to have it, otherwise I'd do like the above posting mentions. As for bolts I use some high heat anti-sieze on the bolt threads. Aloha and good luck, Mahalo

I forgot to mention, on removal of the bolts, like Fred T say's but if it isn't running use a heat wrench (torch) by warming up head area, not the bolt head, the head area surrounding the bolt, then remove.
