I haven't been on for a while, but i have come crawling back. My 72 k5 wouldn't pass emissions so it sat for about a month. Then I finally had it towed somewhere. The shop is reputable and they said my carb is a mess, my cam is totally flat, and the less than 90 compression in each cylinder has covered my spark plugs in oil. I was intending to drive the thing to CO for a few weeks, but that isn't happening. Normally it wouldn't be such a big deal, but my wife is on bed rest from her brain surgery and our copay on that surgery is about $8k give or take a grand. We are both students, so we are living on student loans anyways, and now I am just scratching my head trying to figure it all out. So the question is do I have it towed to a machine shop and have a leakdown test performed and pray that my piston rings are fine and just replace the cam / heads? Or do I replce the entire motor cause the PO was a wack and the other things are probably about to fail too? Do I just have a rebuild done? What would you do if you were in my shoes? Thanks.
