XE Engine block - Does it need welding?

Recommended Posts

Bought a caterham XE engine and was made aware of one of the 2 bolts linking the engine mount to the block (below the carbs) had previously broken.

 

To get the remaining part of the bolt out of the block, someone had cut a max 3mm line into the block to enable the broken bolt to be force screwed out.

 

I am concerned that this may now be a weak point when I fit the engine into my car.

 

2 Options and 1 Question:

 

1) I could purchase very serious high tensile bolts with a fixing agent to lock the bolts in (not fast, but IN!). Or

2) Ask a specialist to cut the 3mm area and weld it to stop any potential of cracking in the block. I would still look to do 1) also.

 

What would you (anyone) recommend?

There are various solutions to repairing cracked blocks which involve 'stitching' and can be done without heat. Something like 'Lock and Stitch'. Welding a block can introduce distortion - I think the whole thing has to be heated up and is not for the feint hearted.

 

Years ago my father had the water jacket repaired by stitcing on a Bristol engine - entitrely succesful.
