Greetings all and Happy New Year!
This weekend, I will attempt to remove the head from the engine on my 1951 XK120 OTS. The car has been in storage for many years and the engine is well and truly frozen. I have used a borescope to examine the cylinders and nothing looks amiss. All piston tops appear to be in good shape and the bores appear to have light surface rust only. Despite that, any attempts to turn the engine are futile. The bores have been soaked with a 50/50 mix of acetone and ATF for a couple of weeks. The engine is destined for a complete rebuild and must come out. Once out, I’ll find a way to unstick things. Of course, the head must also come off which brings me to my quandary. In the current position, I cannot get to the the camshaft sprocket bolts to remove them. What is the process for head removal in this case? I found one thread that suggested cutting the timing chain - which is not a problem, it will be replaced anyway. But if there is a less destructive way, I’m interested.
