SOURCE: bolt torque specs

I have used Haynes service manuals for (hate to admit it) many decades and I recommend you check to see if this one:

http://www.amazon.com/Haynes-Toyota-Automotive-Repair-Manual/dp/1563923513

doesn't cover your engine.

I have found darned few 'holes' in their coverage.

Auto parts stores carry these and I suspect that even though sealed, the sales people will not give you too hard of a time if you explain you want to insure you are getting what you need.

Haynes is not the same as it was 20 years ago before they were acquired by Chilton but the price/utility ratio is still pretty good.
Mostly I'm annoyed by the move to cheaper paper (newsprint)that is fussier, picks up dirt, tears more easily than the better paper of yore.

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

I really really really hope you turned the bolts an additional 90 degrees after torquing to 22 Ft-lbs. Otherwise, you may be taking that head off again.

Best of luck,

You take the head off, remove the crank case cover, take the bolt off the piston journal on the crank shaft, push the piston out of the top of the engine. To get it back in you are going to need a ring compressor and should use plasti-guage to check clearance on the crank

What are the torque specs on intake manifold on Briggs & stratton


if there is thread locking compound on bolt or threads it must be removed, use a tap to clean the threads and a wire brush to clean the bolts. Use a thread locking compound (blue) when reassembling, torque the bolts to 30 ft. lbs. alternating bolt to bolt in 7-10 lb. increments. Recheck the torque after the engine has been ran up to op temp.

Head bolt torque for 16hp horizonal shaft engine


Anywhere from 35 lbs to 220 lbs, depending on the series of your engine. For your engine, the head bolt torque should be 190 lbs.

But I've attached a chart for you to utilize to make sure of your exact engine model series, just in case there was a transposed number, etc.

http://www.small-engines.com/torque.html

Here's the official Briggs & Stratton chart for all versions of their engines, which confirms the 190 lbs torque spec.

Hope you found this Very Helpful and best regards!
