S. C.: I had a cylinder 5 misfire code for the past few months. I changed plugs, coilpacks, O2 sensor, and cleaned the injectors. I finally noticed water on my spark plug, that turned out to be coolant.

I finally realized, it was a cracked head. The fix was more than the vakue if the car. I tried the Bars Leak and followed the complicated instructions. Now there is no more misfire and the car runs great again!

Endle Winters: ##UPDATE AFTER A FEW DAYS

Although this worked for a few days, the head gasket started leaking again so I am going to bite the bullet and pull the head. It was worth the $8.00 to give it a try. In my case, it did not work.

#####

When a head-gasket starts leaking, it can do different things depending on where the leak is. You might see coolant coming from your tail-pipe, or oil in your coolant reservoir, or even coolant leaking from underneath your engine.
I would be hesitant to use this stuff if there were oil seeping into my coolant, or if water was really gushing out of my tail-pipe (indicating a massively warped head or a badly damaged head-gasket).

In my case, my truck over-heated and after fixing the initial problem (water pump went out), I found I had a tiny amount of water coming from the tail-pipe, and one cylinder was misfiring from coolant seeping into it.

I know that the head needs to be pulled and taken to a shop; however, at the moment I am short on money and time to do that. I decided that this would be a good use-case for trying a head-gasket sealant, as I am not looking for a permanent fix but rather something to keep the truck...

gpslouis: 1999 Olds Intrigue with 3.5L engine, 162,000 mile. Head gasket leaks are very common with this engine. Had a very small head gasket leak, losing about 8 oz of coolant in 3000 miles. Could smell the leak but the coolant would boil away from the leak area before it had a chance to drip out.

I used the product as directed about two months ago. The leak stopped immediately and the fix appears to be lasting fine.

Keep in mind that using this product is a two day adventure. You must triple or quadruple flush the cooling system first. There are several lengthy run and cool cycles required. Then flush thoroughly again before adding coolant. Take your time, let the engine cool overnight in the final phase. In the end, your patience and work will pay off with a successful fix.
