As luck would have it the two 8mm, I think, bolts that are on the opposite
side of the temp sensors in the thermostat housing sheared off due to being
seized in the holes due to lack of maintenance on my part. Anyhow I've
managed to drill them out to the point where I don't want to use a larger
drill bit and risk screwing up the threads. In fact in one of the bolts I
tried using an extractor type bit that broke off in the bolt too. Any sage
advice would be greatly appreciated. These are the last two stumbling
blocks, that I'm aware of now, standing in the way of me getting my engine
back in the van so we can go camping................
Help,
