I have a 99 tacoma 3.4L engine. My number 3 spark plug already had a heli coil . Well it popped out and now the #3 hole is to large to put another one in. What is my options now?
If i need to change my head what else would be wise to do to it,like replace water pump,belts,gaskets etc. Thanks

Timing belt, tensioners, etc. I probably wouldn't bother pulling the other head and swapping the HG unless it looks pretty gnarly on the head you have to pull. But if it looks iffy, you're already mostly there.

Replace the knock sensor wire. They get incredibly beat up by the heat. Oh, and reseal the coolant bypass tube. I'd not be surprised if you find some coolant in the valley between the heads.
