K&W 401232 Permanent Head Gasket & Block Repair with Nanotechnology - 32 Fl Oz

works good and it help the problem thanks ...

I used this in my boat engine. It a 1987 OMC 4.3l. I was getting major water in my oil. I was told by multiple people I would need a new engine or at least a new to me. Well me, not wanting to drop 3-5 grand, I decided to give this a try. It F$&%ing worked perfectly . People who have give this product a crappy review either didn't do the right process or the damage was too great. Bottom line get this stuff it truly is miracle juice for your engine

This product did not work and I see this as a waste of Money, will never recommend this any one in the future

Followed instructions exactly, car was running fine, no white smoke, only had bubbling in the reservoir from the head gasket being blown and gases getting into cooling system. After using this car still has the same problem, PLUS started spitting out a ton of white smoke

I tried to use this product to fix a head gasket leak on my 2002 Dodge Caravan. I followed the manufacturer's instruction to the letter. That is; removed the thermostat and flushed the engine to completely remove all coolant from the system. I flushed the heck out of it too. Like five complete refills, starts and drains to ensure there was no coolant. I even had a new radiator installed prior too using the product.Now to be fair after this did not work I ended up trying K-Seal as well, which also did not work - although I did get some results using the K-Seal product. At this point I am rebuilding the upper half of the engine.So, I can't say 100% for sure that this product does not work, it just did not work for me. I don't know that anything would have. But if I had to do it again, I'd use the K-Seal to avoid having to flush the entire system. Although, if it's an old car and it's suffering from a semi-clogged radiator, you could be asking for trouble using any of these type products.I will also add having worked on cars my entire life, regardless of which product you use, these are not "permanent" repairs. I fully expected to have to change the head gasket at some point when the weather got better. So if you are buying this thinking you'll be good to go forever, you are kidding yourself. Just sayin.
