Yep, typical print-o-seal felpros... They've been going belly up now for nearly 20 years. If anyone's running them on their street engines I highly recommend you replace them ASAP. They've also leaked in the Chebbies I've built years ago. I can't imagine how a "knowledgeable" engine builder would ever use them...

So sorry to see that Chas. It would appear you pretty much have a basket case. The block may be sleevable but trauma like that often travels through an engine in ways that aren't readily apparent.
