While adjusting the valves on my iron headed hemi,I noticed a few drops of coolant on a piston.The plug looks like all the others.When starting up after sitting for a while,You have the smell of antifreeze from the exhaust for a moment.I just retorqued the heads,even though they have been on for almost 2 years and they were all good.I am trying to make to the end of this season before taking the engine out to freshen.So my question is,,,do I leave it alone,,,,or use some kind of cooling system sealer,and if so ,WHICH ONE?????????There are many to choose from

I use a can of Bars Leak every time I rebuild
(shouldnt use anti freeze in a race car)

My cometic gaskets will seep a little water with out bars leak

Moroso Ceramic seal

You really could leave it alone as long as you are not having to add to the radiator all the time.

Or you can use a radiator sealer that is compatible with antifreeze and does not require a fulsh afterwords. That leaves out any of the HD versions. They are real caustic and require flushing.

The one I used to use all the time was a wood pulp looking or looked kind of like sand mixed with water or BABY SHizzit. I used it routinely to prevent leaks in the Demon. I just added it and left it in there.

If you literally only saw a couple drops in there and the LAST time you drove the car you only started it to move it a 100 feet then it could have been condensation?

Oh, and another thing I forgot to mention.

Always crack the cap and release the pressure after running it.

I would do a cooling system pressure check with all of the spark plugs out for 15 or 20 minutes and see if it will fill a cylinder up enough to blow coolant out a spark hole on the starter. If so remove the head on that side and have it pressure check, most bad things don't fix themselves, they usually end up hurting somebody or some parts at the best

i am sure the bars leak will do the trick just fallow the directions so you wont have questions on how it works.you have a GREAT CAR.
