3.1l diesel. What is the correct head gasket?


no year? Jeep? one post, and no year.
is this WG jeep say in europe. ? we dont have WG here.
WG started in Europe in 1999.
on this usa forum or in our country no 3.1 VM diesels
i do have your FSM book.
and here is what it states. (different liners used etc)
"CYLINDER HEAD GASKETS
A one piece steel cylinder head gasket is used for
all five cylinder heads.
Cylinder head gaskets are available in three thicknesses.
Identification holes or notches in the right
front corner of the gasket indicate the thickness of
the gasket (Fig. 65).
CAUTION: Piston protrusion must be measured, to
determine cylinder head gasket thickness, if one or
more cylinder wall liners have been replaced.
NOTE: If cylinder wall liners have not been
removed; the same thickness head gasket removed,
may be used.
MEASURING PISTON PROTRUSION
(1) Use special tool VM.1010 with dial indicator
special tool VM.1013 (Fig. 66).
(2) Bring the piston of cylinder no. 1 exactly to top
dead center.
(3) Zero the dial indicator on the cylinder block
mating surface.
(4) Setup the dial indicator on the piston crown
(above the center of the piston pin) 5mm (1/8 in.)
from the edge of the piston and note the measurement
(Fig. 67).
(5) Repeat the procedure with the rest of the cylinders.
(6) Establish the thickness of the steel gasket for
all four cylinder heads on the basis of the greatest
piston protrusion (Fig. 65)
buy the book,end all guessing?

I have a 1997 Isuzu Rodeo 2.6L cylinders 2 & 3 won't fire after vehicle starts but will fire if I unhook cylinder 1 or 4 what will cause this


USA car? must I GUESS?
so you have 2 coil packs. ????
called wasted park
seems you typed the displacement wrong, !!! 2.2L is 4 banger...
1 and 4 fire as a pair
2 and 3 , fire as a pair , in series

so if the spark wires open , you loose a pair,
say #1 opens, you loose #4 with it.
they are wired in series.
if one spark wire grounds out , you lose only THAT spark plug.
but why would you get the odd pack to pack cross talk.
(assumes you have the HV wired right. correct?)
the packs cant be wired up willly-nillly.
this is the 2.2L coil pack.
and IS wasted SPARK system. for sure.
and can not be mixed up
the PCM is hard coded for 1,3,4,2 firing order.
and must be wired right. did you meddle here?
if you unplug the 2 one right , this must not make the 2 on left work.
pulling 1 wire, only kills the adjacent wire. normal.
see the pairs there, at the bottom see those hiddencoil packs mail coils molded to case?
if you are wired right and you have cross talk from 1/4 to 2/3 bank
the pack is bad.

25857019-xm4r4cd100gbehm3txueal2s-4-0.jpg by cross talk i mean, 1;3 effect 1/4 or the reverse.

Rav 4 turbo diesel 1 2 3 cylinders are all working when you take off connector when running no 4 nothing happens


There is a fault with no 4 cylinder. Could be: Faulty new injector, faulty ECM not firing injector, low compression on that cylinder. I'm assuming its a newer common rail model - I suggest getting the injector swapped to another cylinder and see if the problem moves. IE: swap no 2 and 4 injectors - if the problem moves to no 2 then the injector will need to be replaced.

What is diesel engine liner intrusion


You will have to give the make and model of the engine but generally it is the amount that the liner protrudes above the block to produce an effective seal with the head. Too far out and the head will not seal properly on the head gasket and not far enough will allow the liner to move with the piston and fail. It applies to wet liners or semi-wet liners mostly

Cambelt timing marks 4jx1


sounds like the injector sleeve O rings have failed this was common.
if you put a clear plastic piece of hose on supply line for diesel fuel filter to head fitting at front and fuel is not black but normal diesel colour thats good.
then put clear hose on return line fitting at rear of cylinder head and fuel is now darker, engine oil is by passing injector sleeve top O rings and entering into fuel gallery in head.
rocker cover, injector rail, injectors need removing and injector sleeves need replacing as well as O rings and seats.
a special tool is needed to remove the injector sleeves out of the head. you will also need to drain the cooling system before removing the injector sleeves, so coolant is also needed.
dealers have special tool for injector sleeves
