MD2020.....quit while I'm ahead?

Sorry to hijack the thread, but do you also think this is likely the cause, please?

I think it was just a standard elbow, but cost could have been an issue. That said, to make the spacer would have taken a fair bit of time and would have cost something.

the problem is that even if I manage to shift the bolts, there is the issue with the metal missing from the block, you can see the threads of the manifold bolt where the cast iron used to be!

Actually I'm thinking 2030. Don't think there's an HR version for the 2020. Sorry, and good luck!

I'm assuming that if you remove the spacer then the elbow hits something so it's not just a matter of extending the flexible hose?

I think that you do need to remove the bolts to see what you're dealing with. Use heat and penetrating oil if the bolts are too stiff. If the manifold is too badly damaged it might be possible to replace it if it isn't part of the crankcase casting or have it built up with a welder and ground back. This could probably be done in situ.

Those exhaust elbow bolts aren't coming off for love nor money! I stopped short of snapping them this evening. However, the good news is that I removed the exhaust hose, had a good dig around and took some pictures, and the elbow itself appears to be remarkably clean. As it appears that it won't clog up in the short term, I'm going to service the engine and leave well alone (and start saving for a new engine)!

I'll let you know once it's all back together and running.

That sounds like a good plan as shearing the bolts would lead to a much bigger job.

It sounds as if the bolts were not coated with copper grease and were then over-tightened whereas, with the correct gaskets fitted, they only need to be nipped up as they are not load bearing. It's an extremely familiar story.

I'm leaving them tappets alone at the weekend!
