Man you really need to trim the size down on those photos.
I have a Sony digital Mavica and I can put 15 high quality photos on one
1.44 floppy disk. Some of your shots are 2000K !!!!
Question!
Does your engine burn oil?
-----------------
Your mounts are sponge rubber looking, fractured bad and need to be
changed. The tranny mount is broken because all the oil leaking down
the back of the engine from the valve cover and then blowing back has
caused the rubber to disintegrate. Just an educated guess, but bet I am
right.
I would recommend rubber mounts and I would recommend you go to the
dealer for them. Ya I know, the '$tealer', but the stock mounts have
lasted this long, so.... I have torn 3 sets of aftermarket engine
mounts apart in 3 years and my local Jeep shop also recommended OEM
mounts for me.
Do you have oversized shackles on the springs? CJ ones are 3" I think
and YJ ones are 4" I think. Long shackles make a need for axle shims.
No way a 2.5" spring lift needs shims. That is what I have and I have
the YJ shackles that give an extra 1/2" lift.
Oh, CJ's have rock hard springs. I have new OEM springs arched to 2.5"
with the top leaf replaced with a tempered 'keeper' spring and they are
rock hard. The only soft bit I get is from the right air pressure in my
tires....
Steering....
Wheel bearings are a sneaky thing in the front. They need to be
repacked and retorqued on a regular basis. When water crossing or mud
running, I do mine twice a season.
If the wheel bearings are the slightest loose, the steering will
wander. To test them, jack it up and grab the tire at the top and
bottom and pull in and out. If you have play, the bearings need
servicing. They normally should be repacked with every brake pad change
if in normal duty.
A bad ball joint also can cause wander. To test, with the vehicle on
the ground, grab the top of the tire and pull it in and out hard! Get
the Jeep really rocking side to side and then feel for clunks or
shuffles.
Why do you think you need a new clutch?
The boot is real rubber and the oil leaking down from the valve cover
turns it to jelly. Mine was in shreds when I did my frame up rebuild.
Where does the clutch engage on the pedal?
The pedal should have about 3/4" of free, flop around play at the top,
then the clutch should grab about halfway along.
If yours sounds like that it is working perfect. If it grabs at the
very top and you have the top free play, it is worn out.
If no top free play, it needs adjusting. The 'book' adjustment is for
3/4" of free play up top.
With blown tranny and soft engine mounts, the clutch will act very
strange and sometimes grab up top, down low, grind, shudder bad on take
off, bitch and generally not act nice.
If you need a clutch, they are easy to do from the bottom if you don't
mind working under. I am tall and prefer to work from the top so I like
to pull the engine. Have a sweet big tree over my driveway for an
engine hoist anchor too. :-)
I just helped a guy do his in my driveway at -25C temps a couple weeks
ago. There is a post/thread about it here.
He is short and prefers working on his back so he dropped the skid plate
and tranny from the bottom.
I do not think you need to worry about that from your symptoms. Unless
there is more you haven't said?
Oh, the aluminum valve covers leak just as bad if not put on perfectly
clean eh!
My plastic one only has the two nuts up top holding it on! The engine
head isn't drilled and tapped for the side bolts!!!!
Still with only the two nuts and the plastic cover, no leaks because I
made it perfectly clean before setting the RTV in and let it cure!!!
The RTV also takes 24 hours to 'cure' so you don't add oil or go near it
for the 24 hours.

yes, I usually have to put about a quart in every 1500 miles,

Re: help with 81 cj-7 - engine, vibration, steering wander/over steer
I would just go for the valve cover leak and see what happens. Most
likely the bottom ones will go away, if not then you might think on a
rear seal.
It can be done with the engine in place. It is a two piece seal.
