hello everyone i have a 95 2.2 ohv motor and am putting the crank/ timing assembly back together and had a few questions before i button up the lower end.

1. i noticed a oil filter adapter gasket in the fel pro kit i don't use that right? whats it for exactly???

2. is there a easy way to tighten the crank or cam pullies to spec on a motor stand or will i have to wait until i put the flexplate on?

3. i noticed that on the trans side ( mines a auto) of the motor there are 2 fairly big sized bolt holes that go 1. right above the rear cam seal and one right below the rear cam seal, what are they for, it looks like oil goes through them, as it appears that bolts cannot go through them because the triangle plate that holds the rear of the cam would get in the way of driving bolts in them.

Thanks in advance for the help as i am looking to be done with the lower end this week and these are the only things that i have to solve.

the 2 holes on the back are oil galleys' make sure they are plugged. i normally just tighten the cam by holding the crank and the crank by an impact

pics of gasket and holes would be helpful to verify what was said above.

I agree with what was stated above on tightening.

ok the machine shop must have taken them out and discarded them, does any one know the thread pitch and head size with torque spec??? i googled it and came up with a gm part number 140331197 but no picture i think those are freeze plugs could someone verify??


thanks

I've just used an impact-wrench to tighten the cam-bolt on my LN2 in-car when I changed the timing-set in bolt my trucks, once I got them started-in about so-far by hand (As far as you can turn it by hand, that is), and then just slipped a large socket that slid over the crank-snout & a hammer to drive the crank-sprocket back as far as I realistically could then install the timing-cover and slip the crank-pulley flange in place, ran the center-bolt in as far as possible by hand & drove it down with an impact on the lowest setting once, then again with the pulley bolted in place.

Do it just like that & be careful not to cross-thread the bolt by hand or impact, or else you'll need to get a blind-hole tap & chase the threads in the hole & run a die down the bolt, like I did once.

And if you do find yourself chasing the threads in the hole, coat the flutes (Slots on the sides) of the tap with heavy grease (Like the kind used for greasing bal-joints) for the first run-through & then wipe the tap off thuroughly & clean the hole with a bit of brake-clean spray (Flush it!) for the second pass to be sure you've gottren to the bottom, and flush the hole again.


Go beyond the "bolt-on".
