Compression Test

my 93 chevy 1500 4.3 218,000 miles did a compression test 5 out of 6 cly test at 200 - 210 psi the one low cly was 30 psi I pour some oil in the cly still 30 psi do I have a bad valve or what ?

[i would sure think so probably burnt.

Thanks how can you burn a valve?

[QUOTE=keneesha]couldnt tell you for sure looked up on internet and found stuff about rich mixtures?but not sure .i had the same problem on an engine and thats what it was it was missing about 1/8 of the valve either way the heads will have to come off and check it out. maybe bent pushrod but i doubt it either way again the only way to find out is pull out the tools..
