Hey guys. Did a compression test tonight.

1 - 230
2- 220
3 - 205
4- 230


Thoughts ? Comments ?

 

umm from my understanding as long as they are with in near distance from each other you should be good?

 

I don't like that 205 :/ that's all. ESP 3.

 

The way to. Test that ring is take a bottle cap of motor oil and poor in to the number 3 and if it bumps u the comp on that one then oil ring is going

That number is too high to do the oil test. The extra oil alone will bump that number back up to normal whether your piston ring is bad or not. I suggest a leak down test. Have you done a valve adjustment recently?


I was pretty sure that I had a cracked ring but it turned out to be burnt/cracked valves. I had only 120psi on that cylinder.

 

Leak down test...
