Camaro compression test....burnt valves???

I just did a compression test on my camaro, a some of the cylinders read around 150 or so, a few read 95-100. Those low ones could have burnt valves, correct? if so im gonna pull a head off and look. the motor has all new internals ect ect, 1000miles on motor, but it did run low on oil once (long story) wasnt my fault though.

Here is a quick and easy way to figure out if it is a bent/burned valve or rings. Add a little oil to the low cylinder and retest them, if the numbers come up then it is the rings, if the numbers are still low it is a valve problem. Try this before you pull the heads, if it turns out to be the rings then you have no reason to pull the heads, until you are going to rebuild the engine.

Hope that helps, good luck

Have you been having this problem since fired up?

I'll be curious to see how your new comp. test turns out.
