C4s are kinda leak-prone, especially if they sit too much.
I would STAY AWAY from stop-leaks.
The exhaust leak may be "cured" with getting the bolts to the right torque, but don't overdo it, you may hafta RnR it. Be sure you aren't feeling exhaust coming from a heat riser tube port that has no tube in it.
Type F is still available, I have gotten it at Wallet-Mart, AutoZane, O'Really's, Adverse Auto (haha) and is what yours was designed to use. You can use the Mercon Dexron type in a new build but I wouldn't mix the two for a top-off.
