RogerH Posted February 7, 2012 Report Share Posted February 7, 2012 Hi Ash, yes!! I had a look at that. Is it the large(ish) black smear. I'm not sure if it is cracked. It would need MPI testing to say for sure - it looks ugly though. Roger Quote Link to post Share on other sites
Ashley James Posted February 7, 2012 Report Share Posted February 7, 2012 Roger I'm referring to the hole on the left. If you look carefully, there appears to be a couple of cracks, one towards the centre of the engine and another opposite and heading outwards. Quote Link to post Share on other sites
RogerH Posted February 7, 2012 Report Share Posted February 7, 2012 Hi Ash, I see the thing you are refering to. It looks cracklike, but the surface is rather mucky. It needs cleaning and MPI. Roger Quote Link to post Share on other sites
TR 2100 Posted February 7, 2012 Report Share Posted February 7, 2012 Now, back to the crank - solder and a couple of 2BA screws I think Roger Roger - the crank is very hard to drill and tap. Recommend a couple of self-tappers - same as your hip replacement! AlanR Quote Link to post Share on other sites

AlanR Self tappers just aint goin to work on the crank. If ya gona do it proprley Proply correctly then ya gonna need Araldite.

2long Posted February 22, 2012 Author Report Share Posted February 22, 2012 So, to follow through on this thread - the block is toast. The "edm", or spark erosion method would have likely worked. However, the projected cost of the edm process, as well as the cost of cleaning out the byproduct of the edm process, and then specialist welding tactics for the multiple cracks on the stud boss (and possibly elsewhere on the block), basically brought me to my knees. Plus no guaranty there are not other structural problems. So it is a bloody shame, but now its on to the spare block. I will keep my original block as a relic to stay together with the car. So much for my bragging about numbers matching originality! Suggestions for the old block are welcome - so far I have considered adding a glass top for a table, some dirt for a planter, or a stout doorstop. Dan Quote Link to post Share on other sites
