coolant leak

[7duster4]

I posted a while back about a small coolant leak towards the rear of the block, engine/passenger side. Many here thought the last exhaust manifold stud would be the issue. It does make sense being it goes into a water jacket. Unfortuantley dosn't look to be the case. There is still a small leak but I don't think it's coming from there. Last time I was under it looked like between the head and block was slightly wet. Just a small spot though. I only have 10,000 miles on this engine I wouldn't expect a head gasket to be going bad on me. Do the head bolts ever come loose over time? It only leaks if it sits overnight after a drive. I also wanted opinions on stop leak. Such as bars radiator stop leak. Does the stuff really work? I have seen the bottles and it looks like a thick sand material. I'd be nervous dumping that in my radiator.

Any info would be appreciated. Thanks

Well…. It may not look like that is the leak but that doesn't mean it isn't.

I would pull that bolt and put some sealer on it before I do anything else.

Don't "Band-Aid" it with crap in the cooling system.
