Folks if you work on cars this is an easy DIY, I have done it 3 times, the first time I did not torque the bolts correctly and did not change the second seal which is on the OFH, there is one between the block and the OFH and a second between two parts of the OFH. You need to do both since they both go bad at the same time.

I always changed my gasket when I did the oil change and never had an issue with Coolant leaking out. One of the way to know your OFH is leaking besides the fact you have oil all over the front of your motor you will see oil in the coolant reservoir.
