Even the impressive TH400 cases had porosity cited "in the books" since the year they came out.
"Check case for evidence of porosity". about as uncommon as re-building Planetaries. |

My experience with both brands of blocks suggests they both have problems and you need to work with the mfg directly. I have used both Bars & Moroso Ceramic sealer to fix some leaks with excellent results. We currently run 5 different block/head combos so I'm speaking from experience. Like John said this race stuff isn't perfect and I can't afford perfect.

here is a thought -- how about the damn manufacture do a good pressure test on the block BEFORE its sent out -- a little QC would go a long way to save your customer and your reputation. Bottom line is -- If they cant do it right -- maybe they shouldn't be doing it at all.

I don't think the issue then (15+ years ago) or now is so much about problems with either block.
The issue is (and always has been) whether or not the respective manufacturers of each have stood behind their product when there was an issue. If you did your research, Mark...like you suggest the rest of us do...I think you'll find tons of anecdotal evidence of who is firmly standing behind their product, and who isn't.

I'm a hack; but;
That Bars leaks stuff is like mud. I have fixed a SINFUL amount of cracked blocks and heads with this stuff: K&W Metallic Block Seal. https://www.amazon.com/CRC-401016-Me...72848705&psc=1 It's not like mud and works like magic. |

All I'm going to say is engine blocks "break for a reason"... and the "leak for a reason".

And by the same token I'm sure that I've used Bars Leak to repair a slew of cracked heads, blown headgaskets, even external gasket leaks with it. I'm not saying K&W is bad, or doesn't work. I do know from years of using Bars Leak that it does work and GM recommends it, and uses the pellets in most of their new cars, plus they sell it in their parts network. My own 6.5 dually diesel has had it in the cooling system for the last 2 1/2 years, no ill effects whatsoever. The external leak sealed in probably 15 minutes and is dry to this day. The thermostat gasket was leaking and I stopped and grabbed a bottle because I was going to a location about 50 miles away for a meeting, and didn't have time to replace the gasket. These products are fundamentally different in how they work, but to condemn one over the other because you don't like the way it pours out of the container has zero to do with how efficiently it does the intended job. If I remember correctly, K&W will not work with antifreeze, necessitating flushing the cooling system before a repair, and has to cure 24 hours before refilling the system. Not everyone has the luxury of taking that much time away from the vehicles operation. If you go on Amazon (your link) and read the 1 star reviews, there are plenty of people that the K&W did not work for. A few of the reviews said it was solidified in the can. FWIW, not one of the stop leak products Amazon sells has a 5 star rating, and they all have reviews where the products didn't work at all. It isn't a foolproof science, your chances it will work are probably 75% in favor of it working, at least worth a try over a mechanical repair. The one customer said he's in a battle with CRC (parent company for K&W) trying to get his money back from the implied "money back guarantee" on the can. Evidently he didn't get the can with the magic in it. Not sure how many people know this, but if you pour regular table pepper in a cooling system it will seal a leak. I had a Fiero with a leaking heater core that I just grabbed a pepper shaker from a restaurant and poured the entire contents into the radiator. It held for about a week, bought me enough time to buy a heater core until I had enough time to install it. Ground flax seed, as I previously mentioned is what radiator shops pour in the radiator before the send it out the door. Flax seed is also used to lower cholesterol.................  No stop leak is magic, they have their place, and as I eluded to if Bars Leak doesn't work after I tried it 2 times, you're looking at a mechanical repair. It is well worth the effort to at least try it before spending a good deal of money and time for a mechanical repair. If it doesn't work you're out less than 20 bucks and some time spent.

Right on Brad.
A little joke I used to tell my friends about stop leak: "just put rice in there" "Does that work?" " No but you'll have something to eat while you're waiting for the truck." |

There's a dam big difference between fixing a block leak with bar's leak which may hold up fine in a every day stocker but not in a race motor that takes a pounding!
A leak at a casting seam needs to be treated as you would a crack before you fill it by whatever means.

Good luck with your block situation. Maybe kre will do something for you. These threads always seem to end up in the crapper
