[DeTomaso] Oil Leak Fixed. What Torque?

[Himes, Terry (397C)]

Doug (et al),

Lots of great feedback.  I have tightened them all down (no torque wrench) and this weekend
I'm going to clean up the excess oil.  It's not a lot, so it should be an easy job.

My new engine seems to be well broken in and running fantastic.

As everyone has said many times.  These cars are a blast to drive, and turns heads everywhere they
are seen.  The sound catches everyone off guard.  Love it  ;-)

Thanks to everyone!

Terry

Terry,

My 1970 Ford Service manual lists 3 - 5 ft-lbs  for  the Cleveland valve cover bolts which differs from the 10 ft-lbs someone else posted.

Despite the torque spec, I just use a nut driver to snug them up by hand then follow up a week later with another by-hand snug-up and they never loosen after that.

Not exceeding the 5 ft-lbs max is VERY important with the stock stamped steel valve covers as they will easily deform with too much torque.
Cast aluminum aftermarket valve covers are much more forgiving if over torqued.

I use Gaskacinch  to glue the gaskets to the covers then apply a light coating of my favorite Mobil 15W50 motor oil to the gasket surfaces that mate with the heads.  The covers always come off easily after that via a light tap with a rubber mallet without tearing the gaskets.

Hey Pantera Guru's,

I finally got to my Pantera last night. (work is getting in the way of my fun!!)

Simple fix.  ALL my valve cover bolts were loose.  Every one of them.  I tightened them all but didn't want to over tighten them.  Anyone know what the correct torque should be?

I have roller rockers and the taller Ford Racing valve covers for clearance.

Your thoughts?

Terry
