Looks promising. Took a look at timing and its right on. Parts are here and ready to install. Going to remove the oil pan tomorrow and clean out all the debree and get to installing the timing chain. Cant wait to see if this thing runs.

Glad to see it hasn't jumped, though your compression test confirmed it wasn't far enough to bend the valves.

Im a little worried about cylinder 6 but we will see what it does.

Yeah, it might start sealing up again when it runs a bit. If it sat a while with the exhaust valve open it may have built up some junk or rust.

Thats what im hoping for. I did spray some oil down the spark plug hole and try again but didnt change the compression so I know its not rings. Never thought about the valve getting crud on it.

Yeah, especially if it sat in a humid area.

Glad I pulled the oil pan. Thanks for all the help. This is great to have people who know these cars and are willing to share and help out. Appreciate it!

Glad you did. Not a bad job, unlike some other GM FWD engines that are 'lower the engine cradle' jobs.

CathedralCub 10-25-2018 03:45 PM

Blegh yeah glad you did too.

Well got it all back together and the car will run on starting fluid only. The gas tank is full of bad gas so now I have to get that pumped out and hopefully it will run all on its own. Im so happy I found the problem! All thats left to do is find an alternator, put on the water pump pulley, and slap the serp belt back on.
