Looks like she may have slipped timing. I really think that is the best of all evils. The fix is cumbersome with big heavy casting to remove but it's all in front and does not disturb any complicated components or head. A mechanic came over and they say that the rotor does not return to No. 1 every time. Like we thought we thought it did. He is coming back to check again and do a compression test.
Since it's hard for me to believe a low mileage 305 V6 has a stretched chain or broken gear, I guess it can be bad dizzy gear.
