I’m pretty sure it is grammatically correct with no comma. The version you provided is a comma splice.
To slightly change the tense, All the good faith that I had had no effect is grammatically correct with no comma, so the gerund form should also not need a comma.
Perhaps. Regardless it’s outlandish abuse of the tongue IMO and definitely would benefit from the comma because nobody’s going to just bang out 4 had’s in a row in speech without a pause without a justifiable slap across the chops and possibly a challenge to a duel.
“But your honour, he said ‘had’ four times on the trot without pause”
