Cylinder head gasket

Piston height was ok when assembled?

Yes, and coolant was disappearing after rebuild then I'm guessing the 3rd cylinder hydro locked at start and bent the rod.

Head is removed so the crank should manually bar over with little effort and rotate smoothly and not bind at any point. If a rod is bent it will likely bind up at the same crank position(s) for every rotation.

Yes, can be blown head gasket. Check compression on those two cylinders. The sealers almost never work.

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?

with this issue , fouling can mean many things, i,ll assume, & i don,t like assuing at all, ? i,ll assume you mean missfiring inderperforming two different issues, two answers, (1) missfiring ,ok change all plugs and remove and overhaul number two injector, replace it,, (2) fouling,? under performing, this can have a few causes i,ll list all, pressure loss in cylinder due to either worn piston rings or valve seatings, or head gasket,?(a) piston rings, luckily this is probably not the problem as usually all 6 cylinders would be effected, (b) valve seatings , hope its not this as it,s a major opperation involving removing the cylinder head an totally reconditoning it, all valves cleaning and reseating, replacing vavle seals , new head gasket ,inlet manifold gaket , exhaust manifold gasket, a good mechanic can get away with changing only the head gasket, but that ain.t you,unfortunatly, so hope its (a) peter.

cylinder replacement ????? this could refer to the cylinder liners, but you would only do this for a diesel engine if at all......as long as the cylinder head is serviced (machined and pressure tested), and all top engine seals are replaced with new ones, you should not have any further issues.......make sure a compressioin test both wet and dry are carried out to ensure that the head is the only problem

Priority Action Part Type Cause 1 Inspect Head Gasket Head Gasket Leaking Coolant into Cylinders. 2 Inspect Engine (DOMESTIC ONLY) Cracked Cylinder Block Leaking Coolant into Cylinders.

Yuo have engine oil into the coolant system.If your engine is diesel you have two opportunity.First is engine oil cooler/top of oil filter/ and second-cylinder head gasket.If petrol engine-only cylinder head gasket.Any way-change them.

how did the diesel get in there? are you sure its diesel fuel or is it motor oil? then it could be head gasket problem. Or trans fluid, which would make it milky pink? Then it could be the trans cooler in the radiator leaking. If someone accidently put diesel fuel in it then just flush it out. If it has been in there long enough to start ruining hoses then replace those. why does he say gaskets? how does it run? does it overheat? then maybee head gaskets. and resurface heads.

you really need to have your cylinder head opened and checked. Your mechanic is right. The cylinder head might have warped due to overheating or might have a hairline crack were water can seep through. You will be lucky if the head gasket is the only problem.

If this is a gas engine You have probably blown a head gasket. If its a diesel engine of later years 03 or later you probably have an injector failure and or a injector pump failure. I hope this helps.
Thank You,
