Is their a inherent problem with the head gasket in the Mitsubishi pajero's (NJ 1995, 3Lt).Have had 2 replaced in approx. 3 years and just went to do weekly oil/water
check and radiator was empty,oil on the dipstick was milky white, and under oil filler cap milky again.
Am i at fault or is it a pajero issue?, to save some dollars, is replacing the head gasket within the realms of the average guy and his workshop manual or do i pay for my mechanics xmas holiday!
Any usefull advice appreciated!
Paul

Yeah mate you can do a head gasket using the workshop Manuel, thou I am unfamiliar with the Pajero, Some engines can be easy and straightforward and others can be a real pain in the Arse to do.
I would read the Manuel first to see what is involved and get your heard around what you have to do and make sure you have everything you need before you start.
You want a Quality tool kit thou (Not a Cheepie from Super chit). aswell as a toque wrench 1/2" drive, as you don’t what to round any head bolts as if other outing measures fail tyring to drill em out is time consuming and you need to be very careful.
There is also correct loosing, re tightening and toqueing procedure to follow with head bolts the workshop Manuel will show this.
You will need to
check the top of block (deck) flatness with a straight edge and filler gaugers as
well as the head and it may need to be machined too.
If the head gasket has blown this many times there may be some underlying problem.

All of the above mate.
i have had quite a few pageros through my W/S & more than a few had head problems. Do it yourself by all means but dont cut corners & have the head crack tested & shaved before refitting dont just assume its ok most likely it is not. Use a quality replacement head gasket (acl, felpro) no need to buy genuine just dont get the no name brands from ebay ok.
Try to get a mono torque type gasket (set & forget) & remember clean , clean , clean, if you wont eat of it its not good enough!
Follow your work
shop manual to the letter if you are new to this kind of thing & dont be smart thinking you know better, just follow it(the manual) & you will be fine.
before you start make sure you have the correct tools. again read manual (not cheap bleep e that bends like liquorish) & do not skimp on a torque wrench. At least get a kingchrome one but better yet get a REPCO brand type cheap but good quality. Or if you are really keen a warren & brown but your starting to talk dollars there.
Lay all your parts in order of disassembly & put all bolt & nuts back in original holes if possible while waiting for your parts & head (just a couple of threads is fine) mark everything if your unsure.
This is a little rooting around but it will help you out a lot for reassembly specially if your new to this game.

As noted above , the V6 PJ's do tend to have a weak spot when it comes to blowing head gaskets. Mind you , I'm told , they aren't the only ones , the V6 Hilux's had a similar problem.
It may not be helped by driver error , but its certainly not totally drive fault.
Its not at all helped when running a V6 on gas.
