The time and cost involved with the repair of a head gasket get the head checked for cracks etc on my little truck compared to the money I paid for blue devil was a no brainer.sure I took a punt most of these products don't work, I picked the most expensive one which had really good reviews I only needed half so I have another repair in the cupboard if I need it.it worked the truck is running very well I'm very happy
We had a blown head gasket on a supercharged jk wrangler... it was blowing white smoke from the exhaust. And leaking water out onto the ground.. hard to start and running with a miss... also engine light was on... we followed the instructions and it worked... well worth the money... cheaper than pulling it all apart.
