Maybe steam or pressure wash motor and then do a coolant pressure test.
Might have more than just that one leak.

finally found more time to work on my truck.....the rough idle at start-up is back...it's not as bad as before...but it's back. I noticed when you first start it, there is a little black smoke out the tail pipe, and it smells rich. I asked a friend that works on toyotas, and he said it sounded like an injector was "leaking"....I am going to try and replace the injectors...My question is....would you buy the re-man injectors or get OEM????
