Early-mid ‘90s Continental cylinders were well known to have problems, but most of that was the honing and early loss of compression. All Continental big bores have a reputation for poor valve guide life. Some of that from poor rocker geometry. The odd wear at the rocker support is a new one for me. That warrants inspection by a good cylinder shop. I’d appreciate hearing what they say.
Thanks for the input Stewart. As you mentioned with the honing, in theese cylinders you can easily see the wear with the bare eye. The only honing pattern left is at the very bottom where no rings go.. The rest is all mirror finish with clearly visible wear steps at ring reverse areas.
We will install new Cylinders, so maybe these will be machined and used as crankcase hold down plates for maintenance or something
