I'm sure that there are other topics about this but I can't seem to navigate to them ( new to forum ). Anywho my 6.0 leaks a small amount of oil on the rear of the motor on the drivers side by the bell housing only on cold start after it sits all night. And didn't bother me much until today I noticed this a.m when cranked it up and let it run before I left for work about 30 degrees this morning that now it has developed a small coolant leak on the rear of the block on the passenger side. Can't seem to pin point where it's coming from. Any help would be appreciated on the two. Thanks also forgot to mention after the truck warms up both leaks seem to go away
