How to remove/install a 4 cylinder jeep Yj

PCV bad. (or its hose pinched, clogged or even backward)

1. PCV is failing fix this first for $5 or remove it and see how bad blow by is. visually. (remove only valve covers side to test )
2. or cracked or collapsed piston.
3. or cracked head gasket, compression tests pass?

yes one of the best jeeps are YJ, not full 10 stinking married computers , wish every day I never sold my 2002,
2002 is the last good jeep IMO

blow by is most mostly past bad piston rings, even warped cylinder from past overheated engine,

The YJ used a 2.5 L AMC 150 I4 or optional 4.2 L AMC 258 I6 until 1990

which one, 4 or 6 cylinders.???

YJ jeep Jurassic Park

1992 Jeep Wrangler YJ Sahara models
all are great.

1995 YJ if still stock all that is ONE PART, see FSM quote below.
is the fluid dropping, day by day, week by week???
y/n?
yes, then either the slave or mc are bad.
sometimes both can fail, (rust happens inside and is progressive)
what I do , is this. (if not wanting to change out both)
1: look at the MC, if it done leak down either side of the fire wall
it might be good (dont mean the piston seals good but its not leaking, so if fluid drops , (every week say) the the MC is ok
and for sure the slave leaks.

2: so where is your slave. have you looked,? (swaps happen)
most leak and can not be detected as that leak landed on the road to work.
for sure its just 2 parts, here, you know the clutch is ok.
because it works with fluid in the system and bled.
now ILL PASTE THE FSM words out of a real factory service manual.
they are clear.
FSM words, QUOTE:
CLUTCH HYDRAULIC LINKAGE REMOVAL
The clutch master cylinder, slave cylinder
and connecting line are serviced as an assembly
only. The linkage components cannot be
overhauled or serviced separately. The cylinders
and connecting line are sealed units. Also
note that removal/installation procedures for
right and left hand drive models are basically
the same. Only master cylinder location is different.
(1) Raise vehicle.
(2) Remove fasteners attaching slave cylinder to
clutch housing.
(3) Remove slave cylinder from clutch housing (Fig.
9).
(4) Disengage clutch fluid line from body clips.
(5) Lower vehicle.
(6) Verify that cap on clutch master cylinder reservoir
is tight. This is necessary to avoid undue spillage
during removal.
(7) Remove clutch master cylinder attaching nuts.
Note that one nut is accessible from engine compartment
and one nut is accessible from under instrument
panel (Figs. 10 and 11).
(8) Remove clip securing clutch master cylinder
push rod to pedal and slide push rod off pedal pin.
(9) Disconnect clutch pedal position switch wires.
(10) If pedal pin is equipped with bushing, inspect
condition of bushing and replace it if worn or damaged.
(11) Remove clutch hydraulic linkage through engine
compartment.

might have air and may need to be bleed cable or linkage damaged or require adjustment or clutch burnt out needs replacement

this is a faulty clutch master cylinder

The clutch hydraulic control unit cylinder seals have failed. It is inside the bell housing and will need to be replaced.

If you go to this page... then allow pop ups and enlarge the image it is upper right in the picture here:

Here is a parts source.... the cylinder is 3/4 of the way down the page scrolling.

What ever you do... verify that the part is actually leaking. It could be a leaking line and these are NOT cheap to replace. Jeep finally figured out in 1994 they should once again be using a slaved cylinder.

Thanks for using FixYa.

What size engine? 6 or 4 cylinder. Comment back for a solution,thanks.

Check the clutch master cylinder, the line to the slave cylinder on the bellhousing and the slave for leaks. If fluid is low there is a leak. Master can "bypass" as well similar to a brake master in which case it wont leak but the slave won't move when the clutch is applied. If that system is working then the clutch likely has worn out.

no, there is no clutch adjustment. the clutch is hydraulic, and self adjusting, there are several things that can go wrong with these. with normal wear the fluid can run low allowing air into the system, causing a weak peddle. they can also develop leaks in the master and slave cylinders resulting in fluid loss also causing a weak peddle leading to an inopperative clutch. check the fluid level in the clucth master cylinder(next to the brake master cylinder. if it is empty, refill it(it takes brake fluid) then cycle the clutch peddle a few times and check for leaks. if there is air trapped in the line the clutch will need to be bled. there is a bleeder screw on top of the slave cylinder, bleed it just like bleeding brakes.

check for leak at the push rod for the clutch master under the dash and also the slave cylinder and replact the leaking part

slave cylinder needs replaced
