Very slight coolant leak. When pressurized, you can see a small amount of coolant drip off the oil filter.

Anyone got a clue where this is coming from??

 

I have an 02 and my coolant leaks at the reservoir.

 

could be from a hose with a wear spot or the water pump possibly...

 

heads maybe

 

Or it could be from the cross over built into the bellhousing. There are 2 plates bolted back there on the top slants, one goes to the oil filter housing and the other is blocked off. Had a coolant leak on mine and it ended up being a broken bell housing

 

Some good places to look. Thanks for the replies. I know it's not the water pump because that's what I thought it was and why I pressurized it. It's coming from somewhere in the rear of the motor and it's just barely dripping when under pressure.
