Somewhat of a teaser...

Slowly being taken apart for bigger and better things.

The chain and sprockets look great, Has the intake cam been advanced? Did the upper cover bolts break off or does the picture just look that way?

[dude8383]

pic just looks that way...nothing was blown of. It was a really smooth running motor, grandpa driven. Im assuming thats why the motor looks soo good.

How do i remove the camshafts??

Oh, the intake cam may have been advanced, i have no clue as i am tearing apart this motor for the first time. I got it with 140k, so i have no idea what its history is. I just know it wasn't driven hard!

To remove camshafts you have to remove sprocket (better mark their position)  and then unscrew camshafts.

With advanced intake camshaft you will loose all torque and HP over 5k rpm.
As you can see in http://www.catcams.com overlap is small, smaller than on stock engine.

those settings were there before i even got the engine...i only acquired it at 140k. Everything will be done according to spec once i re-install everything

I was referring to the position of the sprocket bolts relative to the slots in the sprockets. Exhaust bolts are centered, intakes are at the end of the slots. Does this mean anything? It looks as if it would effect the cam timing.

i realize that would effect cam timing...but can easily change that when im putting everything back together..

nice pic...a bit washed out, but nice and clear.  Now if we can only get someone to document a complete teardown and rebuild of an M42 then life would be complete.

hehe of course! I gotta get my friend to help me with the crankshaft nut..once i get that off, it goes to machine shop!

[tim_s]

you mean you didn't get the crankshaft nut off when the engine was in the car!? its waaay easier then!
what exactly are your plans for this engine?

haha yeh i shoulda thought of that when it was still in the car...but i know how im going to approach the situation.

Plans:

-engine is going to be bored out to a 2.0
-M50 Lifters
-M44 Valves

And...whatever else needs to be replaced, which i hope will be minimal!

That motor is CLEAN!!!  Nice work.  Replace only the "have to" stuff and get it back on the road!  

Should be good for another 140K.  Just make sure you follow BP's write up on the timing cases.  You want to use silicone gasket sealant along with new gaskets when you put the timing cases back.

yeh i wanted to do that just to be on the safe side...i want a perfect seal!

I can't wait to swap this motor...
