#1 Cylinder no compression

I am disappointed that's there is no discussion about this. Talking to the service manager this is a very common problem. #1 cylinder has no compression. The other 3 seem normal. This car has 180,000 interstate miles. He explained that it had to do with the instant start feature, #1 cylinder is engineered with higher compression. Said I could replace with a crate engine. I want to see why. Disassembly will begin in the coming days and weeks.

Re do the compression test. On the cylinder with no compression, pour a table spoon of oil in it. If that raises the compression, rings are bad. If no change you most likely have a burnt valve or a valve hung open.
