i am wondering if it is a merc ?

anyways i have extracted all the studs now and anything else that bolts into the block.... all went well except one stud which i have sheered off in the block... guess iam stronger than i thought ! on a positive note at least it pulled now before i had gone through countless gaskets and frustration !


GIT !!!!


next step is to get it chemically cleaned and the cam bearings pressed out (and new ones put in)

get the block drilled out now darnit....


bring home, paint and pollish the faces etc prior to rebuild.

You can often get the broken part out by welding a nut on the stud, the heat will expand the stud then when it cools may break its hold on the thread and unscrew, nothing to loose really.

i sheared a bolt trying to get a brake drum off a churchill gearbox today and ended up using the tried and tested nut and weld trick, trouble is everytime i tried to undo it the weld broke and the nut just came off the stud, i'll try again tomorrow when i've more time.

my only concerns with this method in this case is the amount of heat i would need to put into the metal to make it work may cause issues with the casting.

I am going to pop up to a local engineering firm where i used to get my race stuff done so i am sure they can remove it for me before honing and cleaning the block

i was gobsmacked that the engine only has 3 mains !!!! my mini had three mains and the crank was half the length of the V8... under load the engines were prone to crank flex which funnily enough used to blow out the center and furthest main away from the clutch !!! and i even had an end cap let go on the rolling road... we used to fix this issue by milling the center main and putting a strap and ARP bolts on. although overkill i may do this with this engine too. i have seen the strap mods for the V8's before and when it comes to these things i am a bit of a belt and braces kinda geek.

What about 'Spark Erosion' to remove the stud? There must be someone up norf! Ron

Smiles, Rosalind Rebores, British engines, to name but a few... the block has to go in for honing and steam clean anyways so will get them to drill out the stud

The amount of heat from arc welding a nut on the stud is unlikely to harm the block, but will be enough to release the stud.

Where there is swing room like you have I drill a length of flat and weld it onto the stud, it's easier to get a good weld, then use a light hammer to tap the strap this also helps gently break the hold after the heat has done it's part.
