Well, after a glorious 210,000 miles, I have a bad main bearing that has damaged my crankshaft. So next week I will be putting in my order for an H22 from HMO. Swap should be done before January. I'm sad, not only because now I have to spend a bunch of money, but also because that H23 has been so good to me over the years. Its had a good life and will soon be broken down and sold for parts.
I will be happy to have an H22 though.
