Am I Checking the Turn too Much?

[toss]

2 Loose Limpers, I Raise AQ of hearts from MP1, BB and loose lippers call. 4 to the flop for 8.5 SBs.

Flop is JT6 with with two hearts. Checked to me, I bet, only one of the loose limpers call. Villain will call with any piece of the board.

Turn is an 8, villain checks, I check.

Any reason not to take a free card? Villain will doesn't bluff to frequently and for the most part is passive.
