Yes, can happen when a spark plug is cracked when installed, I would remove the spark plugs for an inspection. Here is what it looks like when the spark plug is cracked. This guide can help as well:

Good day, we took it to 3 different mechanics.

1st one said it was the distributor cap rubber and ignition coil.

-so, we replaced it.

2nd said it was spark plug wires and spark plugs.

-this one tested compression, also replaced it.

3rd said the valves is probably burnt but can't confirm without taking out the head again.

--did another compression test.
