What could have caused this?

Taking the head over to Marks tomorrow to take the valves out and pick up a set of Jackson Auto Machine std size valves. Then the head goes to Gosh on Mon. to see whats up with it and reassembly.

just a burned valve does it look broke or like it was cut with a torch

[mark4g63t]

Hard to say. Will know once it's out.

[golden763]

im gonna assume its a burnt valve don't usually just break little chunks off

[mark4g63t]

what causes a burnt valve? lean?

[golden763]

that or to little valve clearance sticking it open a little for some reason seems not possible with hydrolic lifters but who knows happens to saturns all the time

[mark4g63t]

My injectors ohm tested fine and look perfectly clean.

[mark4g63t]

The valve does have jagged edges where it broke.

[golden763]

than maybe a bad lifter pumped up and held the valve open a bit. what happens in saturns is there supposed to be adjusted and when people don't do it enough they wear out of clearance and hang a valve open and they burn just like that.

The cam cap bolt was a little loose.
