ZZ4 lower head bolt leaking water.

[lone73]

I just noticed a water leak on one of the lower head bolts on my zz4 motor on the left bank near the front of the motor. It's also leaking a black goo.

I got a half inch wrench on it and was able to tighten it a bit. Should I just re-torque it down or should I pull it out and reapply some sealer, then torque it.

What do I torque it down to?

Thought I'd post it here since the L98 is similar to the ZZ4 motor.

Thanks

Yes!!!!!!!!!! get a torque wrench and do the bolts over in the proper sequence. They have been known to come loose.

(happened to me)
