Thank you anyway. And particularly for the best M96 rebuild thread by far !
Haha, I did think about taking it apart to inspect it but then I think it's probably not needed.

There is no plug at the bearing end once the bearing is removed it's open, the plug is at the other end which slots into the oil pump!

We are discussing "The Solution" by Raby/LN. I respectfully suggest you reconsider your comment about the plug Duncan and I discussed.
"Factory IMS shafts are not plugged, which is why we have to supply a specially manufactured plug with the IMS Solution" ,So said Jake Raby

The plug is installed with the IMS Solution only. This is done to keep the IMS tube from filling with oil, thereby reducing available oil within the engine by 3/4 of 1 quart.

Watch the IMS Solution installation video at www.theimssolution.com to see how this is installed.

Default Torquing the head bolts

The head bolts are torque-to-yield and are $12 each (you need 24 bolts) so better not make any mistakes!



In Jake's class we used a Snapon digital angle gauge. Here I just used a long 1/2" ratchet and a simple Lisle angle gauge to save some $. Worked like a charm albeit more time to setup.



Tape at 70 degrees to aid reading



All the bolts are marked and sanity checked at the end after each round of angle torquing (total 2 rounds)



Set at 0 degree at the beginning with some torque applied to take up any slack (not shown)

Default Lifter cradle, cams and cam cover



Lifter cradle ultrasonically cleaned by Len



Cam cover ultrasonically cleaned by Len. The cams were cleaned and polished by a local machine shop.




The 3 o-rings behind the lifter cradle...very easy to forget.



Cradle installed
