What is the best sealant to use when putting in a dished freeze plug that has to be flattened out to seat and seal in the counterbore? This is a problem with a 3 times replaced plug that still leaks in a Chrysler L6 head. Bill Large

hi blarge Did you use any sealers? Did you clean the hole before installing the plug, also are there any deep pits or groves from removing the old plug ? you have to make sure there is none, which sealers did not work did you use JB WELD,let dry overnight, and only add water to the system for a few months, and maybe a little BAR LEAK, the CHEVROLET DEALERS sell a similar product.it come two tablets that each new car gets in the cooling system, so the cars that might have a leak will not, they sell this over the counter also, my 3 cents worth, 37RAGTOPMAN

Bill: A core plug that completely flattens out when it is driven in probably will always seep, as there isn't enough tension at the edges. You may be able to fix it with a plug that has a lip, as opposed to just a disc. Most good parts places, such as NAPA, stock a variety of plugs. We use black silicone on the edges, and install Barr's Leaks.

after you have cleaned everything, use old fashioned form a gasket and do not tap on the midle of the plug , only the edges
