Blue Devil Engine & Cooling Sealant

OK guys I have a 1989 Chevy 2500 5.7 V8 with blown head gaskets, I haven't driven it since the head gaskets blew. (about 4 months ago). But I am building my house addition and my buddy just took his trailer back that I was using behind my Explorer to get materials home with. Now I need my truck back on the road, I don't have the time to rebuild the engine at this point so I installed a can of this Blue Devi Sealant. Have you guys had any luck with this stuff. I don't plan on driving it every day and the lumber yard is only aprox 4 miles round trip.

Steve

If you ever find a mechanic in a can you better let him out.
Okay, I`ll edit this post and say, once we used Sodium Silicate, also known as "liquid glass" on blown head gaskets before, and it worked for about 6 months, this was on a 2.8 liter cavalier Z24, but there`s no way to promise it`ll work on all applications since there`s no way to know how bad the damage is, on a friends car which was a honda 4 banger with a cracked head it held about 3 months, which was a shock to us both, but in a small block chevy where the head was cracked in the chamber it didn`t work at all.

DO NOT USE THE BLUE DEVIL STUFF! I DID LAST YEAR AND I'M STILL PAYING FOR IT TODAY!

I used it to stop an imagined leak into a cylinder. Instead in plugged up my radiator and caused an overheating problem. I finally had my radiator rodded out, but I'm sure the block is still full of that crap. I should have known better 'cause I have seen a few engines in which that crap was used in and it just plugged them up. DON"T DO IT!!

sold the Blue devil several times, only had one complaint...and he had a crack approx 5 in long in the side of the block. Have used K & W block sealer on numerous occasions. If you read and follow the instructions, it will work. Like Double vision said.....ya better let him out. None of this stuff is a permanant fix, don't care what they say, however, if ya gotta get the truck going for a little while...you will fix it correctly later................right

Whatever engine sealant you choose to try, i would advise that first you remove the thermostat, then disconnect the hoses from the heater core and either plug them or hook them together. After you have run the engine enough to see if it works you can drain the cooling system and refill will 50/50 anti-freeze and water and put your thermostat back in and hook up the heater hoses. I have used liquid glass and some of the other sealers with good results, but like everyone says it is a temporary fix. The first time I did not do like I told you and my thermostat stuck and my heater core clogged up with sealer. Its really just a shot in the dark but it may buy you some time. In the end you will have to fix it right.

I know this is only a temp fix but I need the truck before I can fix it properly. And yes I will fix it properly, because I need this truck to be a driver, just don't have time right now to fix it properly. I am a auto tech and fix cars properly all day every day. This is my truck so it can get a band aid, if that band aid fails it will only be me that has to walk.

Just got back from a test drive and engine is not overheating, no white smoke from the tailpipe, no blowing coolant back in the over flow bottle.
I know this should not last for any length of time or millage, but like I stated above I need it to drive maybe 8 miles a weekend until I can fix it properly.

No, not still walking, just seen this post again. The truck is running fine, only has aprox 50 miles on it since I used the Blue Devil stuff. But it did stop the head gasket leak. Like I said in the earlier post I will not and do not drive this truck much. Its only being used to haul building materials to my house.

Still not Walking?

hey this question is for Steve. I just bought some of the blue devil stuff myself. but i am kind of skeptical about its reliability and have read it will clog up my engine and the residue that clogs up the engine will be darn near impossible to remove. Now that some time has passed can you give me some info on the eventual performance of your truck, and is it something you would recommend for a 2001 Mitsubishi Eclipse 6 cylinder 3.0L.

I'm thinking about buying it. My 99 Park Ave, which I bought from my friends uncle, started overheating a week after I bought it. Took it in and the shop suggested I go to a radiator shop, and they said they don't know if it's a head gasket or the head itself, but exhaust is getting into the oil. I have never heard of this. Please help guys. I don't have any other car I can drive daily and am broke as hell. -Alex

Oh , I see you aked the same question here. The problem is you wont seal the crankcase with blue devil if the the problem is combustion pressure is getting into the crankcase as it is NOT PART OF THE COOLING SYSTEM.get a grip on the dynamics of the situation here.
Blue Devil works good IF you do it correctly. Follow the instructions to the LETTER. ONCE AGAIN it will not seal a leak of combustion pressure into the crankcase.You had better check the engine compression and do a leak down test or your going to waste your time and money. I would not want to see you do that my friend.

It worked on my 78 Nova with a 305. I blew the head gasket when I started experimenting with timing and carburator tuning. I had my timing too advanced and I leaned out the primary jets. On. A hot AZ day I smashed the throttle and only heard "Nickels in a can" and I blew the head gasket. I was loosing about a gallon of coolant a week.


Its been about a year and still holding up to abuse. Just make sure you flush the system before using it and follow the instructions.

My answer to this is , its a chevy ,it should be an easy fix to put in head gaskets, shouldnt it?
Its not like its a 3.0 liter mitsu twin turbo rice grinder that is near impossible to even change a spark plug on.
If you fix it right the first time it will last.
