Hi guys! I'm the proud owner of an '83 GL wagon, and I've been working on rebuilding the engine for a while now, but before I went to put it back together, I noticed some... cracks? Right at the top of the cylinder. I'm fairly new to engine rebuilding, and yes, I've heard that rebuilding the engines is a losing proposition for these cars, but I'm already elbows deep in this project......

 

Anyways, does anyone know if these need to be fixed before I start putting everything back together? And if so, does anyone have a good recommendation for a machine shop in the Portland area?

If the block material is weldable it will need to be welded. Some pics would help

This is what it looks like up close.

Looks like it needs a good cleaning. I'd want to be sure the aluminum surface is totally flat. The headgasket seals to the aluminum. The top edge of the cylinder liner doesn't matter so much.
