Make sure you clean out the cooling system properly before you do the treatment. Follow the instructions properly. You dont just chuck it in. Has to be added the correct way for the correct time along with the correct driving during treatment & then flushed out. You can leave it a little longer to make sure its properly sealed.
Good Luck !

thanks layback40.......well I got the chemiweld today read the destructions ....... engine flush coming up then I will chuck it down its neck and see what happens it wont take much for the xj to get hot running on water only lol if it buys me a few months great as I only do 11.5 k a day down the river and it is not over heating just surging and sluggish when cold but temps spike if you push it a bit I will eventually pull the head as I want to keep the xj
so I will let everyone know how things go in the next few days ..........................now more beer

well I think I am going to chicken out on the chemiweld I have read so many reviews my head is spinning....or is it the homebrew
needless to say about 70% say its shit hot if the directions are followed...and about 30% say its trouble if you intend to keep the engine/car..................
my cooling system is newish all under 3 yrs old and I don't want to chance gumming it up .... I think I might get a compression tester off ebay only around $20 and test my compression see if the gasket has let go between cylinders
I will post my results of the compression test in the mean time I only drive it 11.5 k a day so I will nurse it but today when trying to get down the river it rained too muddy river mud like glue 20kph in 4x4 sideways it ran perfectly? and on the highway no surging at all? so I think I will start with a compression test
and while the plugs are out crank it and see if any coolant spits out ...............

Save yourself the time,money, and grief and get a quality tester. Had nothing but trouble from eBay test gear. Mityvac is worth the extra little bit imo

I have had a little luck with leaky HG by one at a time loosening each head bolt & re-tightening, if you go an extra 45 degrees after you tighten to spec, this may close a leak. Wont help if you have a crack though.
You do it in the normal tightening order with everything cold if thats what is recommended for head tightening. Dont loosen any more than 1 at a time though.
Its not as good as Chemiweld though.
You may not see much with a compression test, nor turning over without plugs. The color & condition of the plugs is a better indicator.

Chemiweld will plug a leak very well, sets super hard. BUT the collateral damage can be a bit expensive. 1985 new Western Star with Cummins developed a slight coolant weep under front head, Cummins sent a bottle of Chemiweld & said put this in, it won't cause any problem & we'll fix it next time your in. Stopped the leak within 1hr. Next day temps started to come up quickly on a pull, until then it held a constant 80c no matter how hard it was working. Drained coolant & refilled with new & temps kept rising so we decided to pull top tank off rad, about half the tubes were plugged full length. result was a brand new Modine 1600 sq/in hd radiator & never use any thing like it again.

UPDATE
Time moves slow in the outback when you are a pensioner $$ But its Christmas and after much research rockauto gets my business top end gasket set $ 120 ish and new head bolts about $25 but its ....drumroll $114 postage all up about $230 ish couldn't find it or find it cheaper in AU so that's what santa is bringing me ho ho ho
I think I may as well after 380000 k a headjob would freshen the engine up
