glenwyatt is on a distinguished road
Hopefully the intake valve and seat is not damaged. A quick test- With both intake valves closed try putting a small amount of gas around the valves/seats and over time see if it leaks past into the cylinder. If it is sealed then soak up the gas afterwards. idealy, a leakdown test will tell you if the valves or other issues are now present in that cylinder though.
Good detective work BTW!
