Thanks Barney that's good to know , I went in for kseal but was handed "holts sealit" which is for blocks , haven't used it yet just drained the cooling system as I had only water in it till I got the leaks fixed and it's getting cool some nights now and don't need any bigger cracks .My local mechanic suggested getting it welded by the guy who fixed my cam bearing probably from the inside so would have to take the liners out etc .Problem is you have to build it all up to see if it's fixed .

    Seems a common gti problem looking at resto threads surprised there are any blocks left now ,guess too many had leaks /busted heater matrix etc and left the antifreeze out .I know a mate did that years ago and it went for scrap after .

You'll find the crack will be due to corrosion inside the water jacket that has thinned the area. Remember the head bolts put a lot of load into the block in this area.
I'm not saying if couldn't be welded, but I've tried and failed in the past.

I see Tom, I thought it was frost damage , I haven't seen inside the engine but its been without water for possibly 10 years now so could be a right mess inside.

No problem, Leslie - it's not ideal but it has bought me a few months (of hard use!) until the winter and a block change can take place at my leisure.

 

I torqued my head bolts up as per the manual, but having read more on here realise that it's probably excessive, so will be using one of the guides this time - far less stressful on a 30-year old block.

 

If I were you I'd continue the search for a short/long block rather than attempting a repair - they're still out there.

Leslie, here is a pic of the corrosion in one of the blocks I stripped- as Tom says it can be quite bad even with a serviceable replacement.

 

I had to reject this one for a rebuild even though it was a known good engine.
