YB200 crack from bolthole to waterjacket
Good evening everybody
Do any of you have had a crack between headbolt and waterjacket on your 205 or 200 block.... and had it repaired ??
Just discusing it with a friend, weather its possible and reliable enough on our 300-400 bhp Yb´s ????
Surely the block have to come out of the car and will have the deck refaced afterwards!!

Thank you for quick replies...
Sure it all depends. Some thread sealant would properly be adviseable too I guess, for better safety. Ofcause it should be welded by someone familiar with cast iron/welding.
Anybody did this and drive with it??

Yes I might as well say it as it is.. my block has cracked, correct. And serious biip biiiip bip biiiiiiiip crap!!!!!!
It was on ARP stud/nut. Its the third or firth time I use them, but this time the car ran 4-6km .. tadaaa.. capuccino oil .. end of this season (well, the season was already over)
The evening these things where fitted, where discused with my friend, and helper for the evening, that I did use TOOOO much oil on the thread, and I do remember I was generous with the oil, and didnt let the stud, how do you say, "drip of" enough. After some research this COULD be the problem.
As said I have fitted these bolt before wothout problems at all... I even found out I actually torqued them down with little torque!!

I had arp stud n nuts on a 205 block that got very hot/over heated.
1 of the studs snapped and another loosened itself off.
Also a friend had an escort on a 200 block that cracked the block while running in on a rebuild, that had std bolts.

About torque.. yes I am aware of that. As I recall it the stud only must be screwed down no more than fingertight.
Do YOU use any kind of threadlock/sealant in the block when fitting the stud ?
I am sure its my own fault , and its to bad as it was a very nice block with very healthy bores I might be subject to try and test later on.

Dry.. well why not, beside that I have never understood why the stud needed lube when going in the block. I just use moly or engine oil as advised from ARP.

I've always used ARPs on vauxhall and mini engines without a problem before I ever heard about the potential issue with YB's so by the time I had heard about it I was already using them without a problem, and Ive stuck with it since then on other YB's ive built.
But like I say I havent built enough to be able to say that doing them dry solves the problem.

No on the YB's Ive done with ARPs (which is only a handful to be fair so might not be indicative of what others do) Ive just put the studs in totally dry, and so far never had a problem.
