Anyone use K&W fiber head gasket repair?

Look,IVE BEEN through all of this crap before, gasses in the coolant or water in the oil means the head gasket is blown and needs replacing , or the head is cracked,or rarely the block is cracked. I think based on what he said and on the cylinder that is problematic that it is a cracked or warped head or blown gasket. there is nothing you can do but fix it right or junk it/sell it

I've used it as a youngster and it ruined my engine. I understood how it supposedly worked and doubted it, but was desperate and broke. If you've got a leak in the radiation or water jacket to oil passages, an egg in the radiator will seal it up , but it clogs up the radiator too and makes the coolant system not work well

I have as well. I believe it is a very slight leak, as I have no steam in the tail pipe, no coolant in the oil (moving past rings while sitting), and slight bubbling in the over flow. Hell, if it can get me a couple more months its all good, will have picked up a pre owned cert vehicle. May trade this is in to the dealer (stealer)... hahaha...

Supposedly this stuff is brand new. I have used bars, and all the other crap, but found that the K&W was actually interesting... hell, if it works it works, if not, oh well...

Well, like i said, I am telling you here and now believe what you want but it won't work for long. I'm not sure I understand what you are saying, you say there is a gurgling sound which indicates a combustion leak, but gasses are no longer coming from the overflow tube,is this correct?

If so I dont know what to tell you other than good luck

If youve got no coolant in the oil and it isn't losing coolant that fast, change the spark plug in the cylinder that is misfiring and don't do anything. I've driven cars like that without fixing them at all. The misfire is caused by fouling of the plug by coolant more than likely if you're not seeing steam in the exhaust it isn't enough to short the plug from firing from just the small amount of coolant leaking into the cylinder. It's got gunk on it.

I think I understand now. You have loosened the radiator cap to prevent pressuring up the system and the gasses are sscapig there instead of the overflow. thats it.

Temporary solution, how does it compare to Blue Devil?

You already know what you have done then. How many hours would it have taken to fix it right and keep from spending that 10 or $20k for another car?

Thanks everyone...

On a side note, thoughts on fixing this or getting a cheap pre owned cert car? Was looking at a hyundai, a few years old, that comes with a 100K/10 year warranty. Is a 2013 with 7,500 miles for around $14K...

I don't think the Honda is worth fixing, though the tires are relatively new, and I changed out all the struts and shocks here about a month ago... ugh...

I know the auto tranny is not going to last forever, sure that might be coming soon...

All in all, if it is worth $2k, do you think selling it out right for $1k, while telling the person it has HG issues, would be reasonable? I don't want to give it away, nor do I want to be dishonest... thoughts? Thanks.

Yea, but other things I'm sure will fail, at some point, a car can nickel and dime you to death, been there, done that... never again...

With a blown gasket, it's worth scrap. Don't be a shitbag.

This is not true. If it is in pretty solid shape otherwise it is worth at least 1000 dollars. hondas are almost always worth fixing to someone because they last so damn long. You seldom see on in a wrecking yard because some kid buys them to fix up.

A lot o things have changed technology wise over the years but one thing that never seems to change is the market for "motor honeys" and "tune ups in a can" and he shysters that sell this crap ought to be in jail because they always make big claims and the stuff never works. Anyway, the Dupont product is for coolant leaks only, I looked it up. And yes, this could work.

It won't seal a combustion chamber that has blown across the gasket to the water jacket. Not gonna happen

IDW - thanks. Would you get the vehicle fixed, and then sold, or just sell as is and ask for $1000? It is in solid shape. New brakes, tires, rack and pinion, struts/shocks (all OEM) only a couple of dings on the body, paint is still good, etc. Thanks again!

Hard to say. If you're pressed for money the smart thing to do is fix it and keep it.I have a car with 389,000 miles on it and I would trust it over one i got off a used car lot with 100,000 miles on it because I know it and what is wrong with it. If the head isn't cracked , have it milled and cleaned for about 40 or 50 dollars, get a gasket set, and make friends with someone who is mechanically inclined and you should be able to fix it in one day for a total of about 250 dollars. Thats for head gasket set, head bolts m head milling , oil and filter , and a gallon of coolant.

If you don't have the time or money to fix it ,get it running as good as possible and put it in the free trader.thrifty nickle and sell it to some kid. Tell him what you know about it. You can get 1200 for it running, even if it does have a mechanical issue. My first car only had one brake working, the seats were rotted and you could see the road going by through the floorboards. It got about 4 miles to the gallon and I had to work on it more hours than I drove it, but I was glad to have it.

I've used K&W Heavy Duty Block Sealer three times in the past.

It did not clog either radiator.

This particular sealer required all antifreeze to be removed and also required about 12 hours of air dry, system drained, after the leak stopped.

One engine was used in a race car, actually sealed the leak while racing, the engine outlasted three cars. The crack in the side of the block was fairly large, it had frozen in winter temps. It stopped leaking in about 5 laps.

Another was a daily driver that ran three more years with plenty of miles. One day on the interstate, she let go in a cloud of steam.

The third was a slight crack beside a drain plug, again, frozen in winter. Never had a bit of trouble with that one, still running 20 years later.

The stuff can work, and on some pretty severe cracks. Most of the .. "you'll clog your radiator" ... comments come from people using sealer repeatedly on leaks that won't seal.

Sorry, didn't read all your thread, can't handle any more experts today.

Good luck!

If you are mechanically inclined, why don't you replace the head gasket? It isn't that hard if you have some good tools and a service manual.

Thanks. I have the money but not the time. Been restoring an older vehicle, now going on a year, getting to the point that my "love" is slipping... hahahaha... anyways, I found a pre owned cert Hyundai Accent with 7K miles for $12K bucks.

I am just wondering if at what point the Honda, yes could keep going, but could crap out, ie transmission, or something, else...

I have a call into someone to see what the cost will be to fix the headgasket, if its relatively cheap, I may get it fixed and sell it to a family member...

No time... plus I'm in the middle of a classic car restoration.

I have the tools, and know how, just don't have the desire, nor the time... mostly desire. Burnt out on cars...
