Hi,
Can anyone suggest, apart from pulling the Engine out how to repair a crack in Engine Block/Timing Case,the location being where the Alternator adjuster retaining Screw is tightened I noticed this as I was about to change the Belts,can anyone name a good Ally/Metal Bond Epoxy & what would the success rate would be?I'm guessing there is someone out there that has used such stuff ?

I'd use any of the magic metals.....I have a £500 tub of ceramic carbide I use for bodg...er repairing unique parts.....and a tig welder if I want a proper job.

Saw a Cosworth race head repaired with JB weld.....still running afaik.

Magic metals - might hold or might not? Can't say I've been impressed to date. Tend to think of it as an aesthetic bodge material and on an engine block (with heat cycles) I have serious doubts as to longevity of 'repair'. Not what you want to hear but I've got to be honest.

I would be tempted to drill it out and put a bolt through with a nylock nut and a washer at each side, as well as the magic metal stuff on the crack.

The nut/bolt/washers will spread the load around the hole rather than in it directly, hopefully making it last longer for you.

While the belts are off have a check for play in the crank pulley. Its usually that on its way out that kills off belts
