Nickmow Posted February 29, 2012 Share Posted February 29, 2012 (edited) Shortly after I got my jeep last year I discovered the block had a crack in it. It had been rather well glassed over. this weekend I took time out to strip the remaining resin off and discovered a fairly large bodged up weld job. It all underneath the distributor. Not stitched that I can see, but some of the weld is now cracked too :embarrassed:. Bodged up a repair with a bit of JB weld and it's stopping the water leaking for now. Question is what are my options ? If its a case of a replacement block any ideas where I would look for one ?

A fairly common problem, if your block is otherwise ok and not leaking internally, ie water in the oil best seek a professional repairer and see if its repairable with stich/welding, don't attempt to weld it yourself, you'll cause more damage, good Jeep blocks are very scarce, been a few on ebay but there is always the risk buying one in worse state with internal cracks. the alternative is to buy an ex French army Hotchkiss new recon engine available from various dealers Edited February 29, 2012 by Nick Johns Quote Link to comment Share on other sites More sharing options...
MHillyard Posted February 29, 2012 Share Posted February 29, 2012 universal jeep supplies recommend the hotchkiss ones and apparently they are very popular compared to the old ones because they are better built or something and less liable to crack, they would also fit the original head. But that depends on if you want to compensate with a hotchkiss engine and have people at shows saying that you have the wrong engine.

I wrote a detailed post on here when I first joined but have no idea how to find it.Do it yourself and save £. p.m me if you want a detailed advice on how to do this, John.

paulbrook Posted February 29, 2012 Share Posted February 29, 2012 There are plenty of folks who offer stitching services and the results are excellent. For a really good welded repair (but you will need to rebore and deck) then try Cast Iron Welding in Liecester. Depending on the location of the crack and its severity it can be stick welded. Remember dont panic - its a jeep engine not a faberge egg. Heres a tractor block that I did recently with a cheap arc welder and a few quids worth of the right rods: Quote Link to comment Share on other sites More sharing options...

Nickmow Posted February 29, 2012 Author Share Posted February 29, 2012 Thanks for the advice chaps, as imple search revealed this thread http://hmvf.co.uk/forumvb/showthread.php?5204-Cracked-block Which has some good advice too. Think I'll have to get an expert to have a shufty at it. No intention of welding, but wonder if the bodged up repair didn't do more damage, whenever it was done.

deadline Posted February 29, 2012 Share Posted February 29, 2012 The secret to cast iron welding is proper heat up, weld with the proper filler, stress relieve and cool down. Its quite simple if you have the ovens to do it. Quote Link to comment Share on other sites More sharing options...

Pete Ashby Posted February 29, 2012 Share Posted February 29, 2012 Iv'e used Slinden Services (look them up on the web) with good results, it will cost you £50 to ship your block to them and they will undertake a free feasibility study and give you an estimate before undertaking the work then they carry out a full pressure test and arrange shipment back to you. I would not recommend you try to weld the block yourself, the cast is very thin and without proper temperature stabilisation both up and down you will set up all sorts of stress in the block.
