Just wanted to let you guys know that this stuff really works.
We have a 2003 Nissan Altima 2.5 that has 193,000 miles and it started having a really rough idle on a cold start. It threw a CEL for misfire code. Pulled it in the garage, pulled the plugs and when I looked inside the #4 cylinder, there was coolant pooling in. Literally saw coolant filling the cylinder. It's a common issue with these motors above 150k. Since it needed tires as well, we weren't sure about putting money into her. The interior and body are in great shape so I was torn. Looked into replacing the head gasket and the cost would've been about $400, but I was worried about getting the block decked as well since it had an aluminum block and I only saw MLS hg's for this application. We decided to try Blue Devil, $40 plus new thermostats and gaskets, $25. To my surprise, it worked! This was two weeks ago. No rough idle, CEL went away on its own and it drives like a champ.
I personally wouldn't use this on my dsm, but for any other car, I'm willing to give it a shot.
True mechanic in a bottle!
