If there are no scars or if the scars are minimal and can be cured with a cylinder-hone, there is no need to replace the engine.

Aight just did a compression test and here are the numbers
Cylinder
#1 150
#2 0
#3 150
#4 145

Now remember number 2 cylinder is where the porcelin on the old plug was cracked and has oil on new plugs and didnt make no difference when i pulled the wire while running so could it be rings only or do u think anything could have happened to the piston? Im tryin to fix this ASAP cus the car is suppose to be sold. THANX

Re:What Happened?
 

Ive been talkin to a friend who thinks the valves could be stuck open in that cylinder, does anyone have an opinion on that?

Re:What Happened?
 

Pour some oil (about 4 or 5 cork full) through the spark plug hole into cylinder # 2 and then do another compression test. If the reading is higer, it is the rings. If the reading is the same, you have a sticking valve.

Re:What Happened?
 

4 or 5 what? and if it is the valves sticking can it be fixed or have to be replaced? could it be a possibly it could be both cus would it smoke out the valve cover and dip stick if it was a sticking valve and how can i tell w/o takin it to a machine shop? I just wanna see if i can find this out b4 i pull the piston but thanx for the info im gonna try that t/m to see if the comp. is diff.

I didn't read all the post.
First thing that came to mind when I read your post is...that you broke a ringland.

Re:What Happened?
 

Ive also been told that i should have atleast some compression if it were the rings or is the ringlands totally diff. and show no compression? i just wanna make sure its nothin is wrong with the head b4 i put it back on again.Thanx for the input
