Hey guys, the accord v6 I have has 180K and the head gasket looks to be leaking on the rear driver's side corner. I usually don't like using stop leak products, but I was wondering if anyone has used BlueDevil Head Gasket Sealer? The product has good reviews, but I was wondering if it would plug up things like the radiator, heater core, etc. I was hoping to get another 2yrs. out of this car before buying another one.

Amazon.com: BlueDevil Head Gasket Sealer - 32 ounce(38386): Automotive


Thanks,
Tony

Honestly its not too hard to change the gasket all together all you really need is one of those 30$ socket sets, a torque wrench a few hours in the afternoon and a beer in the long run, you will need to do it eventually its also not that expensive >$100 Cheers, let us know what yo go with

The question is why is it leaking? If the gasket was eaten by electrolysis then putting the sealer in their is not the right solution. I would replace the head gasket and flush the cooling system.

Are you sure it's the head gasket and not the valve cover gasket.?

I don't think you'd see a head gasket leak from the outside. They usually blow and your coolant enters the combustion chambers.

How would a valve cover gasket leak coolant?

If the issue was caused by overheating, you can't simply replace the head gasket without checking to see if the head is warped. Check the block too... If warped, you then get to take it to a machine shop to have it resurfaced. Also a great time to replace thermostat, waterpump and check valve clearances.

Checking for warpage...

I've used Blue Devil twice for a head gasket leak. The first time was on my 96 Aerostar. The size of the hole where the coolant was leaking was too big for it to work so that was a failure. The 2nd time was on my neighbor's 07 Cebring and it worked great. It all comes down to the size of the breach. If I recall, the maximum gap it will fill is 1/16".
