I have a 1990 Honda Civic Hatch and the second to the left piston has no compression at all. Couple of my friends said are either the piston ring or a valve is burned. What Do Yall Think?

To find out why your cylinder has lost compression, remove the spark plug and pour a little bit of motor oil into the cylinder. Check the compression after you have poured some oil into it. If the pressure goes up, the piston rings have gone out. If the pressure stays the same, you have a head problem with the valves or head gasket.

ask a good mechanic in your area the repairs will probably be more than the car is worth unless you can do it yourself.good luck maybe trade it in

i own a repair shop,and i think it might have burnt a hole in the piston on it,,i have seen this happen a few times,,and it only knocks the compression out on one cylinder when it does this,,you might want to pull the head and look at it,,this is about the only way you,ll ever know for sure,good luck with it,i hope this help,s.,,have a good x-mas.

Do what the first guy said to see if it is your rings.If you have access to a little mini LED light or a mini mag that you can get a look down through the spark plug hole and take a look at the top of the piston...you might be able to get a visual on a hole in the piston or something.

I just went through this in November. I'd bet that you have little tono compression in the third piston either. The Cylinder Head and/or Gasket likely has a crack or flaw. Very pricy job. Best soultion, or at least what I did, was to find a used engine and do a swap.The costs of changing the head is usually more than a used engine by the time a shop is done with you. My car is also a 1990 Civic Hatchback 1.5l 16 v. I'd bet you can still drive the car but it goes to a " Fill the oil and check the gas " car in short order. Best of luck.
