So, my 99 maxima still blows a little smoke and i’m pretty sure it is a head gasket issue, does anyone recommend Bar’s Leaks Engine Repair 2 part formula? Also, cleaned off 250k of grime with Gunk and my have watered the injectors…I let it sit for a couple of days to dry after noticing knocking immediately after Gunking. I was going to add Sea Foam, any concerns there either? Thanks for any input… ---

An additive may help a head gasket coolant leak in cases where the combustion chambers are not breached but I’m not a believer at all that any additive will help in cases where they are. SeaFoam is a great product but I don’t see that SF is going to help much of anything here. If water is suspect then the spark plugs, wires, and so on need to be dried out. ---

Thanks for the input ok4450, I appreciate it. So, putting the stuff in cannot hurt but may not solve the problem…
