Help!

 

I'm putting everything back together after a head gasket change on a 96' 2.5L. Bolting on Camshaft Caps and sheared a couple of bolts.

 

They looked a little bit coroded at the top of the threads so I bought a new set of bolts from Subaru. Now bolting up again I have sheared two of the new bolts (and stripped a couple threads). I am torquing to 14 ft lbs (168 in.lbs.) I checked my torque wrench and it is good.

 

I am now backing off to 10 ft.lbs. Is this o.k? Has anyone else had this problem? What is up with Subaru bolts not withstanding specified torque? Do I have the correct torque spec for these?

 

Thanks,

Are you using a Hayes Manual? if so they are wrong on the torque spec for the front caps. It's 7.2 ft lbs. It is 14.5 on the center and rear. but they are tighten on a sequence to prevent shearing them off. See attached .pdf

That is a misprint in the manual. the larger cam bolts do take 14ft/lbs, the smaller ones that also hold the camshaft seals only take 7ft/lbs. This was corrected in a later revision of the manual. When I talked to a subaru specialist, he said that the factory manuals are notorious for errors like this.

Well thats a bummer.

 

All my bolts are the same size though.

 

I found a diagram in chilton that showed 7.0 ft.lbs for all bolts labeled T1 which was all the cam cap bolts.

 

I went and torqued all to 7.0 ftlbs.

 

Maybe I'll tighten up the middle and center a bit or go all the way up to 14 again on these and hope for the best?

 

Thanks for the info.
